This enables building BCM4908 "raw" image that can be flashed using
bootloader web UI. It requires serial console access & stopping booting
by the "Press any key to stop auto run".
It's easy to build vendor like CHK image but it can't be safely flashed
using vendor UI at this point. Netgear implements method called "NAND
incremental flashing" that doesn't seem to flash bootfs partition as
provided.
Above method seems to update vmlinux.lz without updating 94908.dtb. It
prevents OpenWrt kernel from booting due to incomplete DTB file. Full
Netgear R8000P support can be enabled after finding a way to make vendor
firmware flash OpenWrt firmware including the 94908.dtb update.

bcm4908img is a tool managing BCM4908 platform images. It's used for
creating them as well as checking, modifying and extracting data from.
It's required by both: host (for building firmware images) and target
(for sysupgrade purposes). Make it a host/target package.

This device is a Senao-based product
using hardware and software from Senao
with the tar-gz platform for factory.bin
and checksum verification at boot time
using variables stored in uboot environment
and a 'failsafe' image when it fails.
Extremely similar hardware/software to Engenius EAP1200H

Use a similar upgrade method for sysupgrade.bin, like factory.bin,
for Senao boards with the tar.gz OEM upgrade platform,
and 'failsafe' image which is loaded on checksum failure.
This is inspired by the OEM upgrade script /etc/fwupgrade.sh
and the existing platforms for dual-boot Senao boards.
Previously, if the real kernel was damaged or missing
the only way to recover was with UART serial console,
because the OKLI lzma-loader is programmed to halt.
uboot did not detect cases where kernel or rootfs is damaged
and boots OKLI instead of the failsafe image,
because the checksums stored in uboot environment
did not include the real kernel and rootfs space.
Now, the stored checksums include the space for both
the lzma-loader, kernel, and rootfs.
Therefore, these boards are now practically unbrickable.
Also, the factory.bin and sysupgrade.bin are now the same,
except for image metadata.
This allows for flashing OEM image directly from openwrt
as well as flashing openwrt image directly from OEM.
Make 'loader' partition writable so that it can be updated
during a sysupgrade.

ath79/tiny kernel config has
CONFIG_MTD_SPI_NOR_USE_4K_SECTORS=y
from commit
05d35403b2
Because of this, these changes are required for 2 reasons:
1.
Senao devices in ath79/tiny
with a 'failsafe' partition and the tar.gz sysupgrade platform
and a flash chip that supports 4k sectors
will fail to reboot to openwrt after a sysupgrade.
the stored checksum is made with the 64k blocksize length
of the image to be flashed,
and the actual checksum changes after flashing due to JFFS2 space
being formatted within the length of the rootfs from the image
example:
0x440000 length of kernel + rootfs (from sysupgrade.bin)
0x439000 offset of rootfs_data (from kernel log)
2.
for boards with flash chips that support 4k sectors:
saving configuration over sysupgrade is not possible
because sysupgrade.tgz is appended at a 64k boundary
and the mtd parser starts JFFS2 at a 4k boundary.
for boards with flash chips that do not support 4k sectors:
partitioning with 4k boundaries causes a boot loop
from the mtd parser not finding kernel and rootfs.
Also:
Some of the Senao boards that belong in ath79/tiny,
for example ENH202,
have a flash chip that does not support 4k sectors
(no SECT_4K symbol in upstream source).
Because of this, partitioning must be different for these devices
depending on the flash chip model detected by the kernel.
Therefore:
this creates 2 DTSI files
to replace the single one with 64k partitioning
for 4k and 64k partitioning respectively.

By using the same custom kernel header magic
in both OKLI lzma-loader, DTS, and makefile
this hack is not necessary anymore
However, "rootfs" size and checksum
must now be supplied by the factory.bin image
through a script that is accepted by the OEM upgrade script.
This is because Senao OEM scripts assume a squashfs header exists
at the offset for the original "rootfs" partition
which is actually the kernel + rootfs in this implementation,
and takes size value from the header that would be there with hexdump,
but this offset is now the uImage header instead.
This frees up 1 eraseblock
previously used by the "fakeroot" partition
for bypassing the OEM image verification.
Also, these Senao devices with a 'failsafe' partition
and the tar-gz factory.bin platform would otherwise require
flashing the new tar-gz sysupgrade.bin afterward.
So this also prevents having to flash both images
when starting from OEM or 'failsafe'
the OEM upgrade script verifies the header magic numbers,
but only the first two bytes.
Example:
[ "${magic_word_kernel}" = "2705" ] &&
[ "${magic_word_rootfs}" = "7371" -o "${magic_word_rootfs}" = "6873" ] &&
errcode="0"
therefore picked the magic number
0x73714f4b
which is
'sqOK'

...and max flash offset
The mtdsplit parser was recently refactored
to allow the kernel to have custom image header magic.
Let's also do this for the lzma-loader
For example:
When implemented together,
this allows the kernel to "appear" to be a rootfs
by OEM software in order to write an image
that is actually kernel + rootfs.
At the same time,
it would boot to openwrt normally
by setting the same magic in DTS.
Both of the variables
have a default value that is unchanged
when not defined in the makefiles
This has no effect on the size of the loader
when lzma compressed.

Most (all?) of the realtek devices have two u-boot config partitions
with a different set of variables in each. The U-Boot shell provides
two sets of apps to manipulate these:
printenv- print environment variables
printsys- printsys - print system information variables
saveenv - save environment variables to persistent storage
savesys - savesys - save system information variables to persistent storage
setenv - set environment variables
setsys - setsys - set system information variables
Add support for multiple ubootenv configuration types, allowing
more than one configuration file.
Section names are not suitable for naming the different
configurations since each file can be the result of multiple sections
in case of backup partitions.

This way MTD "bootfs" partition will be always 8+ MiB. This should be
enough for any custom / future firmware to fit its bootfs (e.g. big
kernel) without having to repertition whole flash. That way we can
preserve UBI and its erase counters during sysupgrade.
