4014ba376c Revert "Revert "nvram: increase NVRAM size to 64 KiB""
This reverts commit r45579.

With the latest change r46251 ("nvram: fix "Segmentation fault" caused
by setting memory out of buffer") nvram utility shouldn't crash anymore.

It was tested on 3 brcm47xx devices:
1) Unknown with 0x10000 NVRAM size (0x8000 offset)
2) Linksys E1000 V2.1 with 0x10000 (0x8000 offset)
3) Linksys WRT300N V1 with 0x10000 (0x8000 offset)

And 3 bcm53xx devices:
1) Buffalo WZR-600DHP2 with 0x160000 NVRAM size
2) Buffalo WZR-1750DHP with 0x10000 NVRAM size
3) Netgear R6250 V1 with 0x180000 NVRAM size
(all using 0 offset)

This is an important change as it allows reading whole NVRAM. This may
critical when reading some basic configuration (e.g. switch ports).

9f15849910 nvram: fix "Segmentation fault" caused by setting memory out of buffer
Some MTD partitions with NVRAM have content starting in the middle. In
such case offset is set and nvram_header returns pointer to the middle.
It means we have to respect offset when calculating remaining space.

By the way use real MTD partition size (nvram_part_size variable) as we
may want to bump NVRAM_SPACE in the (very near) future.

63bb07b28c Revert "nvram: increase NVRAM size to 64 KiB"
This reverts commit ff84c27a281bc19df19bc62ee8688cca5586f6e3.
This tool has really broken size handling (many values hardcoded), it
crashes right now in case of NVRAM not filling whole MTD partition.

The loop was giving up too early as it never expected NVRAM smaller
than 0x10000.

7e3272f422 nvram: increase NVRAM size to 64 KiB
For years Broadcom devices use 64 KiB NVRAM partition size and some of
them indeed have it filled in more than 50%. This change allows handling
whole NVRAM e.g. on Netgear WNDR4500 and Netgear R8000.

The same fix was applied to kernel in upstream commit 6ab7c29.

d94fb398f6 nvram: drop check for WGT634U using /proc/diag/model
We don't have broadcom-diag for months or years now and the correct
solution is to simply don't have "nvram" partition on WGT634U anyway.

0c4c05f0e7 nvram: use correct variable name for MTD partition size
Sytax of /proc/mtd is following:
dev:    size   erasesize  name
which means that sscanf "mtd%d: %08x" reads size, not erasesize.

c10d97484a Add more license tags with SPDX identifiers
Note, that licensing stuff is a nightmare: many packages does not clearly
state their licenses, and often multiple source files are simply copied
together - each with different licensing information in the file headers.

I tried hard to ensure, that the license information extracted into the OpenWRT's
makefiles fit the "spirit" of the packages, e.g. such small packages which
come without a dedicated source archive "inherites" the OpenWRT's own license
in my opinion.

However, I can not garantee that I always picked the correct information
and/or did not miss license information.
