fce35bce0f config: support new symbol intro'd in kernel 4.12
Symbol CONFIG_INITRAMFS_FORCE allows to ignore the value passed by the
bootloader.

By default, all symbols containing INITRAMFS are wiped from the final
config and then re-added conditionally.

Add support for this symbol, as the build will stop otherwise
questioning the user about this option:

* Restart config...
*
*
* General setup
*
Cross-compiler tool prefix (CROSS_COMPILE) []
Compile also drivers which will not load (COMPILE_TEST) [N/y/?] n

...

Initial RAM filesystem and RAM disk (initramfs/initrd) support
(BLK_DEV_INITRD) [Y/n/?] y
Initramfs source file(s) (INITRAMFS_SOURCE) []
Ignore the initramfs passed by the bootloader (INITRAMFS_FORCE)
[N/y/?] (NEW)

589621b1c0 config: make CONFIG_ALL_* select other CONIFG_ALL_* options
Select the other CONFIG_ALL_* options in the hierarchy when the master
option is selected. Currently CONFIG_ALL_KMODS is not selected when the
build bot selects CONFIG_ALL_NONSHARED for example.

Now the rtc kmods should get build when CONFIG_ALL_KMODS,
CONFIG_ALL_NONSHARED or CONFIG_ALL and CONFIG_RTC_SUPPORT are selected
like it is done by the build bots for targets with rtc support.

ab20c638b6 x86: Set default baud rate on Geode images to 115200
Prior to commit 1496b95a0 ("x86: clean up default grub baudrate
settings") we had three different baud rates for the Geode targets:
19200 for net5501, 38400 for alix2, and 115200 for Geos.

It doesn't seem that there's a very good reason for varying from our
default 115200 baud, so let's make the Geode target do that instead.

4cc1f1ac1c x86: revert default root size back to 256 MB
2 GB is overkill and was only added to allow unlimited ext4 resizing,
which is a pretty rare use case. 256 MB allows resizing up to 256 GB,
which should be good enough for almost all users.

A lot of this is mostly irrelevant anyway, since you can just use
squashfs + ext4 overlay.

dc6cc04016 config: ext4: increase x86 rootfs size to 2GB to support online resize2fs
The current default rootfs size of 256MB in conjunction with 4K blocks
produces an ext4 filesystem which lacks the appropriate amount of backup GDT
entries to support online-resizing.

For x86 targets, increase the default rootfs size to 2048MB which allows
online resizing the filesystem to up to 2TB which is the current theoretical
maximum for LEDE, due to missing GPT support on the root block device.

Note that the filesystem artefact will not occupy 2GB on the build system as
the make_ext4fs utility uses sparse files to generate the filesystem images,
so the actual disk usage is much lower. Furthermore the filesystem images
are gzip compressed, shrinking them to only a few megabytes on the download
server.

config: enable shadow passwords unconditionally
Configurations without shadow passwords have been broken since the removal
of telnet: as the default entry in /etc/passwd is not empty (but rather
unset), there will be no way to log onto such a system by default. As
disabling shadow passwords is not useful anyways, remove this configuration
option.

The config symbol is kept (for a while), as packages from feeds depend on
it.

3242c07649 mvebu: add sdcard image creation script
Added gen_mvebu_sdcard_img.sh to facilitate creating an fixed-size sdcard image,
adding the bootloader and populating it with actual data.

Added the required rules for creating a 4GB sdcard image according to this layout:
p0: boot (fat32)
p1: rootfs (squashfs)
p2: rootfs_data (ext4)
This should be generic to any mvebu boards that can boot from block storage.

Added the new sdcard image to the Clearfog image profile.

08257a4053 apm821xx: use lzma compression for the initramfs images
The MR24's u-boot takes it sweet time decompressing the
LZMA-packed initramfs image. A user reported that
compared to the old gzip method in v2: it "takes a ton
longer to decompress like 4\x the old boot time for
decompression".

This patch also fixes a issue with the WNDR4700's initramfs
image getting to big and causing the following u-boot crash
during the decompression:

"Uncompressing Multi-File Image ... Error: inflate() returned -5
out-of-mem or overwrite error - must RESET board to recover"

This patch fixes both issues by reverting the MR24's initramfs
compression method back to gzip. And choosing to compress the
initramfs within the initramfs image as LZMA by default.

33beafa8d8 Configure IPv6 kernel options in config/Config-kernel.in
Revision 46834 changed IPv6 support from a module to builtin. But
since the configuration of the IPv6 kernel options was left in
package/kernel/linux/modules/netsupport.mk, this means that an
empty kmod-ipv6 module was still being generated (not packaged).

This patch moves the configuration of the IPv6 kernel options to
config/Config-kernel.in to remove this last bit of the module.

Note that CONFIG_IPV6_PRIVACY was dropped (enabled by default
since Linux v3.13), so this option is no longer needed.
