01a1e21863 kernel: mtdsplit_uimage: replace "openwrt, okli" parser
The only difference between the "openwrt,okli" and the generic
parser is the magic.  Set this in device tree for all affected
devices and  remove the "openwrt,okli" parser.

0988e03f0e ath79: Add support for OpenMesh MR1750 v2
Device specifications:
======================

* Qualcomm/Atheros QCA9558 ver 1 rev 0
* 720/600/240 MHz (CPU/DDR/AHB)
* 128 MB of RAM
* 16 MB of SPI NOR flash
  - 2x 7 MB available; but one of the 7 MB regions is the recovery image
* 3T3R 2.4 GHz Wi-Fi (11n)
* 3T3R 5 GHz Wi-Fi (11ac)
* 6x GPIO-LEDs (2x wifi, 2x status, 1x lan, 1x power)
* 1x GPIO-button (reset)
* external h/w watchdog (enabled by default))
* TTL pins are on board (arrow points to VCC, then follows: GND, TX, RX)
* 1x ethernet
  - AR8035 ethernet PHY (RGMII)
  - 10/100/1000 Mbps Ethernet
  - 802.3af POE
  - used as LAN interface
* 12-24V 1A DC
* internal antennas

Flashing instructions:
======================

Various methods can be used to install the actual image on the flash.
Two easy ones are:

ap51-flash
----------

The tool ap51-flash (https://github.com/ap51-flash/ap51-flash) should be
used to transfer the image to the u-boot when the device boots up.

initramfs from TFTP
-------------------

The serial console must be used to access the u-boot shell during bootup.
It can then be used to first boot up the initramfs image from a TFTP server
(here with the IP 192.168.1.21):

   setenv serverip 192.168.1.21
   setenv ipaddr 192.168.1.1
   tftpboot 0c00000 <filename-of-initramfs-kernel>.bin && bootm $fileaddr

The actual sysupgrade image can then be transferred (on the LAN port) to the
device via

  scp <filename-of-squashfs-sysupgrade>.bin root@192.168.1.1:/tmp/

On the device, the sysupgrade must then be started using

  sysupgrade -n /tmp/<filename-of-squashfs-sysupgrade>.bin

bcb311497d ath79: consolidate common definitions for OpenMesh devices
The shared image definitions for OpenMesh devices are currently
organized based on device families. This introduces some duplicate
code, as the image creation code is mostly the same for those.

This patch thus derives two basic shared definitions that work for
all devices and only requires a few variables to be moved back to
the device definitions.

4fbdadc0bf ath79: apply Engenius ECB1750 style to OpenMesh MR900 RGMII cfg
The OpenMesh MR900 is a modified version of the Exx900/Exx1750 family.
These devices are shipped with an AR803x PHY and had various problems with
the delay configuration in ar71xx. These problems are now in the past [1]
and parts of the delay configuration should now be done in the PHY only.

Just switch to the configuration of the ECB1750 to have an already well
tested configuration for ath79 with the newer kernel versions.

CPU:         Atheros AR9342 rev 3 SoC
RAM:         64 MB DDR2
Flash:       16 MB NOR SPI
WLAN 2.4GHz: Atheros AR9342 v3 (ath9k)
WLAN 5.0GHz: QCA988X
Ports:       1x GbE

Flashing procedure is identical to other ubnt devices.
https://openwrt.org/toh/ubiquiti/common

Flashing through factory firmware
1. Ensure firmware version v8.7.0 is installed.
   Up/downgrade to this exact version.
2. Patch fwupdate.real binary using
   `hexdump -Cv /bin/ubntbox | sed 's/14 40 fe 27/00 00 00 00/g' | \
    hexdump -R > /tmp/fwupdate.real`
3. Make the patched fwupdate.real binary executable using
   `chmod +x /tmp/fwupdate.real`
4. Copy the squashfs factory image to /tmp on the device
5. Flash OpenWrt using `/tmp/fwupdate.real -m <squashfs-factory image>`
6. Wait for the device to reboot
(copied from Ubiquiti NanoBeam AC and modified)

Flashing from serial console
1. Connect serial console (115200 baud)
2. Connect ethernet to a network with a TFTP server, through a
   passive PoE injector.
3. Press a key to obtain a u-boot prompt
4. Set your TFTP server's ip address, with:
   setenv serverip <tftp-server-address>
5. Set the Bullet AC's ip address, with:
   setenv ipaddr <bullet-ac-address>
6. Set the boot file, with:
   setenv bootfile <name-of-initramfs-binary-on-tftp-server>
7. Fetch the binary with tftp:
   tftpboot
8. Boot the initramfs binary:
   bootm
9. From the initramfs, fetch the sysupgrade binary, and flash it with
   sysupgrade.

The Bullet AC is identified as a 2WA board by Ubiquiti. As such, the UBNT_TYPE
must match from the "Flashing through factory firmware" install instructions
to work.

Phy0 is QCA988X which can tune either band (2.4 or 5GHz). Phy1 is AR9342,
on which 5GHz is disabled.  It isn't currently known whether phy1 is
routed to the N connector at all.

51360a913b ath79: make Engenius fakeroot partitions read-only
For:

 - ENH202 v1
 - ENS202EXT v1

These boards were committed before it was discovered
that for all Engenius boards with a "failsafe" image,
forcing the failsafe image to load next boot
can be achieved by editing the u-boot environment like:

  `fw_setenv rootfs_checksum 0`

So it's not necessary to delete a partition to boot to failsafe image.

0070650df4 ath79: move small-flash Engenius boards to tiny
This moves some of the Engenius boards from generic to tiny:

 - EAP350 v1
 - ECB350 v1
 - ENH202 v1

For these, factory.bin builds are already failing on master
branch because of the unique situation for these boards:

 - 8 MB flash
 - an extra "failsafe" image for recovery
 - TFTP does not work (barely possible with 600 MTU)
 - bootloader loads image from a longer flash offset
 - 1 eraseblock each needed for OKLI kernel loader and fake rootfs
 - using mtd-concat to make use of remaining space...

The manual alternative would be removing the failsafe partition.
However this comes with the risk of extremely difficult recovery
if a flash ever fails because TFTP on the bootloader is bugged.

The phy label/node name should correspond to the reg property.

While at it, use more common decimal notation for reg property itself.

* 64 MB of RAM
* 16 MB of SPI NOR flash
  - 2x 7 MB available; but one of the 7 MB regions is the recovery image
* 2x 10/100 Mbps Ethernet
* 2T2R 5 GHz Wi-Fi
* 6x GPIO-LEDs (3x wifi, 2x ethernet, 1x power)
* 1x GPIO-button (reset)
* external h/w watchdog (enabled by default)
* TTL pins are on board (arrow points to VCC, then follows: GND, TX, RX)
* 2x fast ethernet
  - eth0
    + builtin switch port 1
    + used as LAN interface
  - eth1
    + 18-24V passive POE (mode B)
    + used as WAN interface
* 12-24V 1A DC
* internal antennas

WAN/LAN LEDs appear to be wrong in ar71xx and have been swapped here.

Flashing instructions:
======================

Various methods can be used to install the actual image on the flash.
Two easy ones are:

ap51-flash
----------

The tool ap51-flash (https://github.com/ap51-flash/ap51-flash) should be
used to transfer the image to the u-boot when the device boots up.

initramfs from TFTP
-------------------

The serial console must be used to access the u-boot shell during bootup.
It can then be used to first boot up the initramfs image from a TFTP server
(here with the IP 192.168.1.21):

   setenv serverip 192.168.1.21
   setenv ipaddr 192.168.1.1
   tftpboot 0c00000 <filename-of-initramfs-kernel>.bin && bootm $fileaddr

The actual sysupgrade image can then be transferred (on the LAN port) to the
device via

  scp <filename-of-squashfs-sysupgrade>.bin root@192.168.1.1:/tmp/

On the device, the sysupgrade must then be started using

  sysupgrade -n /tmp/<filename-of-squashfs-sysupgrade>.bin

d0a9cf662e ath79: increase openmesh sysupgrade copy block size
The upgrade script for the openmesh sysupgrade procedure used always an 1
byte block size. This made it easier to seek the correct position in the CE
image and to make sure the right amount of data was copied. But this also
meant that the reading/writing of data required an excessive amount of
syscalls and copy operations.

A 5.4MB big sysupgrade image on an OM2P-HS v3 needed roughly 120s for the
write operation (170s in total) during the sysupgrade.

But it is possible to reduce this overhead slightly:

* index access to read the file size can be done in single 8 byte chunk
  (while doing the seek with byte granularity) because each size entry is
  example 8 bytes long
* the fwupgrade.cfg can be read as one block (while seeking to its position
  using its actual byte offset) because it should be rather small and fit
  into the RAM easily
* the kernel can be read in 1KB blocks (while seking to its positions using
  its actual byte offset) because the the size of the kernel is always a
  multiple of the NOR flash block size (64KB and 256KB)

This results in a sysupgrade write time of roughly 90s (140s in total).

This could be reduced even further when also using larger chunks for the
rootfs. But the squashfs rootfs image is at the moment always

  (256KB or 64KB) * block + 4 bytes

long. It would be expected that the time for the sysupgrade write could be
reduced to roughly 30s (80s in total) when busybox's dd would support
the iflag count_bytes.

9d96b6fb72 ath79/mikrotik: disable building NAND images
The current support for MikroTik NAND-based devices relies on a
gross hack that packs the kernel into a static YAFFS stub, as the
stock bootloader only supports booting a YAFFS-encapsulated kernel.

The problem with this approach is that since the kernel partition is
blindly overwritten without any kind of wear or badblock management
(due to lack of proper support for YAFFS in OpenWRT), the NAND flash
is not worn uniformly and eventually badblocks appear, leading to
unbootable devices.

This issue has been reported here [1] and discussed in more detail
here [2].

[1] https://forum.openwrt.org/t/rb433-bad-sector-cannot-start-openwrt/71519
[2] https://github.com/openwrt/openwrt/pull/3026#issuecomment-673597461

Until a proper fix is found (or the stock bootloader supports other
filesystems), we disable building these images to prevent unknowing
users from risking their devices.

Thanks to Thibaut Varène for summarizing the details above.

1fb40a72da treewide: use more descriptive names for concatenated partitions
A few devices in ath79 and ramips use mtd-concat to concatenate
individual partitions into a bigger "firmware" or "ubi" partition.

However, the original partitions are still present and visible,
and one can write to them directly although this might break the
actual virtual, concatenated partition.

As we cannot do much about the former, let's at least choose more
descriptive names than just "firmwareX" in order to indicate the
concatenation to the user. He might be less tempted into overwriting
a "fwconcat1" than a "firmware1", which might be perceived as an
alternate firmware for dual boot etc.

This applies the new naming consistently for all relevant devices,
i.e. fwconcatX for virtual "firmware" members and ubiconcatX for
"ubi" members.

While at it, use DT labels and label property consistently, and
also use consistent zero-based indexing.

      only use it to flash Original firmware from Engenius
      or risk kernel loop or halt which requires serial cable

  Method 1: Firmware upgrade page:

    OEM webpage at 192.168.10.1
    username and password "admin"
    Navigate to "Upgrade Firmware" page from left pane
    Click Browse and select the factory.bin image
    Upload and verify checksum
    Click Continue to confirm and wait 3 minutes

  Method 2: Serial to load Failsafe webpage:

    After connecting to serial console and rebooting...
    Interrupt uboot with any key pressed rapidly
    execute `run failsafe_boot` OR `bootm 0x9f670000`
    wait a minute
    connect to ethernet and navigate to
    "192.168.1.1/index.htm"
    Select the factory.bin image and upload
    wait about 3 minutes

Return to OEM:

  If you have a serial cable, see Serial Failsafe instructions
  otherwise, uboot-env can be used to make uboot load the failsafe image

  *DISCLAIMER*
  The Failsafe image is unique to Engenius boards.
  If the failsafe image is missing or damaged this will not work
  DO NOT downgrade to ar71xx this way, it can cause kernel loop or halt

  ssh into openwrt and run
  `fw_setenv rootfs_checksum 0`
  reboot, wait 3 minutes
  connect to ethernet and navigate to 192.168.1.1/index.htm
  select OEM firmware image from Engenius and click upgrade

Format of OEM firmware image:

  The OEM software of EAP350 is a heavily modified version
  of Openwrt Kamikaze. One of the many modifications
  is to the sysupgrade program. Image verification is performed
  simply by the successful ungzip and untar of the supplied file
  and name check and header verification of the resulting contents.
  To form a factory.bin that is accepted by OEM Openwrt build,
  the kernel and rootfs must have specific names...

    openwrt-senao-eap350-uImage-lzma.bin
    openwrt-senao-eap350-root.squashfs

  and begin with the respective headers (uImage, squashfs).
  Then the files must be tarballed and gzipped.
  The resulting binary is actually a tar.gz file in disguise.
  This can be verified by using binwalk on the OEM firmware images,
  ungzipping then untaring.

  The OEM upgrade script is at /etc/fwupgrade.sh

  Later models in the EAP series likely have a different platform
  and the upgrade and image verification process differs.

  OKLI kernel loader is required because the OEM software
  expects the kernel to be no greater than 1024k
  and the factory.bin upgrade procedure would
  overwrite part of the kernel when writing rootfs.

Note on PLL-data cells:

  The default PLL register values will not work
  because of the external AR8035-A switch between
  the SOC and the ethernet PHY chips.

  For AR724x series, the PLL register for GMAC0
  can be seen in the DTSI as 0x2c.
  Therefore the PLL register can be read from uboot
  for each link speed after attempting tftpboot
  or another network action using that link speed
  with `md 0x1805002c 1`.

  uboot did not have a good value for 1 GBps
  so it was taken from other similar DTS file.

Tested from master, all link speeds functional

4d0c442a0a ath79: expand factory.bin support for some Senao Engenius boards
Newer EnGenius software that still uses the tar.gz platform
  instead of the custom header requires more checks for upgrading,
  but their script includes a way to skip them...
  the existence of a file in the tar.gz called failsafe.bin

  Their upgrade script has these lines:

  \#pass check when upload with full image file
  [ "${errcode}" -eq "1" ] && [ -f failsafe.bin ] && errcode="0"

  This overrides the script's "errcode" variable
  which can be set if any of the following actions/checks fail:

  - untarring of the upload

  - magic number for kernel: "2705"

  - magic num for rootfs: "7371" or "6873"

  - md5sums for each file in the format
	filename:md5

  - existence of a file matching FWINFO*
	that it has boardname in the name somewhere (grep)
	that the 4th field of separator "-" is at least 3 (version)

  Otherwise we would need to generate md5sums in this strange format
  and touch a file with specific requirements in the name.

  This does not effect boards where the advanced checks do not apply.

  otherwise, uboot-env can be used to make uboot load the failsafe image

  *DISCLAIMER*
  The Failsafe image is unique to Engenius boards.
  If the failsafe image is missing or damaged this will not work
  DO NOT downgrade to ar71xx this way, it can cause kernel loop or halt

  ssh into openwrt and run
  `fw_setenv rootfs_checksum 0`
  reboot, wait 3 minutes
  connect to ethernet and navigate to 192.168.1.1/index.htm
  select OEM firmware image from Engenius and click upgrade

TFTP recovery:

  rename initramfs to 'vmlinux-art-ramdisk'
  make available on TFTP server at 192.168.1.101
  power board
  hold or press reset button repeatedly

  NOTE: for some Engenius boards TFTP is not reliable
  try setting MTU to 600 and try many times

Format of OEM firmware image:

  The OEM software of EnStationAC is a heavily modified version
  of Openwrt Altitude Adjustment 12.09. One of the many modifications
  is to the sysupgrade program. Image verification is performed
  simply by the successful ungzip and untar of the supplied file
  and name check and header verification of the resulting contents.
  To form a factory.bin that is accepted by OEM Openwrt build,
  the kernel and rootfs must have specific names...

    openwrt-ar71xx-enstationac-uImage-lzma.bin
    openwrt-ar71xx-enstationac-root.squashfs

  and begin with the respective headers (uImage, squashfs).
  Then the files must be tarballed and gzipped.
  The resulting binary is actually a tar.gz file in disguise.
  This can be verified by using binwalk on the OEM firmware images,
  ungzipping then untaring.

  Newer EnGenius software requires more checks but their script
  includes a way to skip them, otherwise the tar must include
  a text file with the version and md5sums in a deprecated format.

  The OEM upgrade script is at /etc/fwupgrade.sh.

  OKLI kernel loader is required because the OEM software
  expects the kernel to be no greater than 1536k
  and the factory.bin upgrade procedure would otherwise
  overwrite part of the kernel when writing rootfs.

Note on PLL-data cells:

  The default PLL register values will not work
  because of the external AR8033 switch between
  the SOC and the ethernet PHY chips.

  For QCA955x series, the PLL registers for eth0 and eth1
  can be see in the DTSI as 0x28 and 0x48 respectively.
  Therefore the PLL registers can be read from uboot
  for each link speed after attempting tftpboot
  or another network action using that link speed
  with `md 0x18050028 1` and `md 0x18050048 1`.

  For eth0 at 1000 speed, the value returned was
  ae000000 but that didn't work, so following
  the logical pattern from the rest of the values,
  the guessed value of a3000000 works better.

  later discovered that delay can be placed on the PHY end only
  with phy-mode as 'rgmii-id' and set register to 0x82...

727eebbad1 ath79: Fix fallback to bootloader cmdline on empty DT bootargs
The MIPS code is supposed to fall back to u-boots bootargs whenever the
/chosen/bootargs property is missing. But this feature was accidentally
disabled when the boot_command_line was initialized with an empty space
just to work around problems with early_init_dt_scan_chosen.

But this feature is necessary for some boards which have a dualboot
mechanism and whose u-boot is calculating the correct partition at runtime
without writing this information back to the u-boot-env.

7073ebf0f9 ath79: add support for Senao Engenius ECB350 v1
FCC ID: A8J-ECB350

Engenius ECB350 v1 is an indoor wireless access point with a gigabit ethernet port,
2.4 GHz wireless, external antennas, and PoE.

**Specification:**

  - AR7242 SOC
  - AR9283 WLAN			2.4 GHz (2x2), PCIe on-board
  - AR8035-A switch		RGMII, GbE with 802.3af PoE
  - 40 MHz reference clock
  - 8 MB FLASH			25L6406EM2I-12G
  - 32 MB RAM
  - UART at J2			(populated)
  - 2 external antennas
  - 3 LEDs, 1 button		(power, lan, wlan) (reset)

**MAC addresses:**

  MACs are labeled as WLAN and WAN
  vendor MAC addresses in flash are duplicate

  phy0	WLAN	*:b8	---
  eth0	WAN	*:b9	art 0x0/0x6

**Installation:**

  - if you get Failsafe Mode from failed flash:
      only use it to flash Original firmware from Engenius
      or risk kernel loop or halt which requires serial cable

  Method 1: Firmware upgrade page:

  OEM webpage at 192.168.1.1
  username and password "admin"
  Navigate to "Firmware" page from left pane
  Click Browse and select the factory.bin image
  Upload and verify checksum
  Click Continue to confirm and wait 3 minutes

  Method 2: Serial to load Failsafe webpage:

  After connecting to serial console and rebooting...
  Interrupt uboot with any key pressed rapidly
  execute `run failsafe_boot` OR `bootm 0x9f670000`
  wait a minute
  connect to ethernet and navigate to
  "192.168.1.1/index.htm"
  Select the factory.bin image and upload
  wait about 3 minutes

**Return to OEM:**

  If you have a serial cable, see Serial Failsafe instructions
  otherwise, uboot-env can be used to make uboot load the failsafe image

  *DISCLAIMER*
  The Failsafe image is unique to Engenius boards.
  If the failsafe image is missing or damaged this will not work
  DO NOT downgrade to ar71xx this way, it can cause kernel loop or halt

  ssh into openwrt and run
  `fw_setenv rootfs_checksum 0`
  reboot, wait 3 minutes
  connect to ethernet and navigate to 192.168.1.1/index.htm
  select OEM firmware image from Engenius and click upgrade

**TFTP recovery** (unstable / not reliable):

  rename initramfs to 'vmlinux-art-ramdisk'
  make available on TFTP server at 192.168.1.101
  power board while holding or pressing reset button repeatedly

  NOTE: for some Engenius boards TFTP is not reliable
  try setting MTU to 600 and try many times

**Format of OEM firmware image:**

  The OEM software of ECB350 v1 is a heavily modified version
  of Openwrt Kamikaze. One of the many modifications
  is to the sysupgrade program. Image verification is performed
  by the successful ungzip and untar of the supplied file
  and name check and header verification of the resulting contents.
  To form a factory.bin that is accepted by OEM Openwrt build,
  the kernel and rootfs must have specific names
  and begin with the respective headers (uImage, squashfs).
  Then the files must be tarballed and gzipped.
  The resulting binary is actually a tar.gz file in disguise.
  This can be verified by using binwalk on the OEM firmware images,
  ungzipping then untaring.

  The OEM upgrade script is at /etc/fwupgrade.sh.

  OKLI kernel loader is required because the OEM software
  expects the kernel size to be no greater than 1536k
  and otherwise the factory.bin upgrade procedure would
  overwrite part of the kernel when writing rootfs.
  The factory upgrade script follows the original mtd partitions.

**Note on PLL-data cells:**

  The default PLL register values will not work
  because of the AR8035 switch between
  the SOC and the ethernet port.

  For AR724x series, the PLL register for GMAC0
  can be seen in the DTSI as 0x2c.
  Therefore the PLL register can be read from u-boot
  for each link speed after attempting tftpboot
  or another network action using that link speed
  with `md 0x1805002c 1`

  However the registers that u-boot sets are not ideal and sometimes wrong...
  the at803x driver supports setting the RGMII clock/data delay on the PHY side.
  This way the pll-data register only needs to handle invert and phase.

  for this board no extra adjustements are needed on the MAC side
  all link speeds functional
