The vendor firmware checks for a bmt header in the last 528 erase blocks
of flash. The OpenWrt partition table did not respect that requirement,
and therefore the vendor and openwrt chainloader fight over those blocks
on every boot, potentially corrupting data stored in UBI blocks there.
This commit increases the size of the reserved_bmt partition to avoid
that fight.
Although the vendor bootloader only seems to touch the final 250 erase
blocks[1], the original vendor firmware system partition ended at
0x1be00000[2], so to be conservative, the consensus is to use that as
the end of mtd2 (ubi) partition and leave the last 528 blocks for mtd3
(reserved_bmt).
From https://openwrt.org/toh/gemtek/mxf-w1700k:
[1] OEM bootlog: [ 5.324337] bmt pool size: 250
[2] OEM bootlog: [ 5.478927] 0x000008600000-0x00001be00000 : "system"
Adds a compat_version to warn users to re-install to accomodate the
shrunken mtd2 ubi partition.
Fixed two nits suggested by Claude, zero padding a hex value and removed
an extra space.
Removed the wildcard setting of compat_version for other boards, as
suggested by Robert Marko, set compat_version only for the w1700k.

Due to issues surrounding the implementation of the vendor BMT/BBT
on Airoha, upstream ATF + uboot has switched to UBI flash partitions.
However, some devices shipped on this platform are bootloader locked,
and thus it is impossible to replace ATF + uboot.
During testing for the Gemtek W1700K (#17869), sysupgrades from Linux
(which is unaware of the underlying BMT/BBT) would occasionally write
data into blocks which were remapped by the vendor uboot when it was
read on the following reboot, causing a soft brick.
An acceptable workaround [1],[2] was discussed where an intermediate
uboot would be written by the vendor uboot (which is aware of Airoha
BMT/BBT). This chainloader would then ignore the regions of flash
used by the vendor uboot, and store all relevant data inside of UBI.
UBI would then be used to handle bad block management. As the vendor
ATF + uboot do not read or interact with the UBI region, we would avoid
unwanted remaps from BMT/BBT.
This commit introduces support for building such a chainloader, by
packaging u-boot and DTS into a FIT image; to be flashed like a kernel.
Configuration for the Gemtek W1700K is provided as an example of how the
chainloader is used.

It is more accurate to describe the contents of the FIP as
compressed, instead of the FIP itself becoming compressed.
Update variable naming accordingly.

Changes:
* update to v2026.01 (this brings up EN7523 SoC support)
* drop upstream patches
* refresh and adapt an7583 support patches (changes based on
https://github.com/Ansuel/openwrt/commits/main-airoha-6.12/)
* add ethernet switch mdio support from upstream U-Boot
Notable changes:
* make an7583 memory initialization similar to an7581 one
* add an7583 scu/chip_scu helpers to access scu/chip_scu regmaps.
* fix misprint in an7583 'system-controller@1fb00000' node name
* always use board dts for nand partitioning
Notes about en7523 support
--------------------------
This set of patches brings up more or less complete support of EN7523 SoC.
Unfortunately, building of en7523 bootloader will require en7523-bl2.bin
and en7523-bl31.bin blobs which is not available at the moment.
This is the only known blocker for adding en7523 bootloader support.

This patch removes dirty hack used to:
* operate with flash
* pass flash page settings to linux driver via SNFI registers
It has been proven that spinand flash page size is actually unnecessary.
We can get all required data from dirmap requests. Thus this patch
series drops the hack and do things properly.
After this fix (and corresponding linux fix) the hack is not needed
anymore.

Introduce support for U-Boot for Airoha EN7581/AN7583. For EN7581
initial patch are already in U-Boot mainline and doesn't require
backport, for AN7583 some patch are still pending but already posted
upstream.
Also add for now, precompiled binary for ATF BL2 and BL31. Support for
ATF is planned and will come later.
