A bug has plagued bl2 which caused failure to boot and bricked Linksys
E8450 and Belkin RT3200 devices in case of correctable bitflips being
detected during a read operation. A simple logic error resulted in read
to be considered errornous instead of just continueing in case of
correctable bitflips.
Address this by importing a patch fixing that logic error.
The issue, which has been dubbed as the "OpenWrt Kiss of Death", and is
now a thing of the past.
Users should preemptively update bl2 to prevent their devices being at
risk.

Import pending patches to set pinconf settings for SPI-NAND pins on
MT7622 identical to what the old proprietary preloader did.
Should further increase the reliability of some SNFI-attached SPI-NAND
flash chips.

With recent updates of TF-A the previously already fixed bug slipped
back into the source tree. Again, reorder bl2 init for MT7622 and
initialize WDT only after DRAM init has completed to avoid the
notorious hang.

Always enable built-in 2.5G PHY on MT7988 for now, so that it can be
used. In future it would be nice to be able to switch power and MDIO
access via address 0 at run-time in Linux, both, to be able to use
external PHYs at address 0 and to reduce power consumption on systems
not using the built-in 2.5G PHY.

MediaTek's ARM Trusted Firmware v2.7+ allows the images inside a FIP
structure to be compressed. Make use of that for boards with NOR flash.

The updated sources bring support for the MT798x Filogic SoC family.
Add builds for MT7986 with most supported storage types, each for DDR3
and DDR4 configurations.
A better solution for skipping bad blocks on SPI-NAND connected via the
SNFI interface has been implemented upstream, so drop local patch.
Add pending patches [1] and [2] to fix boot on existing MT7622 boards.
Tested on BananaPi BPi-R64 (SDMMC, eMMC, SPI-NAND), Linksys E8450 and
Ubiquiti UniFi 6 LR as well as upcoming Bananapi BPi-R3 board for which
support will be added in future patches.

Add patch to skip bad blocks when reading from SPI-NAND. This is needed
in case erase block(s) early in the flash inside the FIP area are bad
and hence need to be skipped in order to be able to boot on such damaged
chips.

Use bl3 size of 0xa0000 instead of 0x80000 in NOR flash.
This results in bl3 ending at 0xc0000 which is where the legacy
bootchain typically puts U-Boot environment.

Add patches for mkimage to allow using it instead of the binary-only
'bromimage' tool to generate bl2 for MT7622.

All necessary blobs are now contained in the upstream repository, no
more wild replacing of blobs needed.
This new version also contains new storage drivers for (SPI-)NAND which
already comes with support for FM35Q1GA, so that patch can be dropped
as well.
Tested on:
* Bananapi BPi-R64
- sdmmc-2ddr
- emmc-2ddr
* Linksys E8450
- snand-1ddr
All works fine (booting Bananapi BPi-R64 from SD Card does NOT require
a signed image, so patch arm-trusted-firmware-mediatek to allow doing
that).

The Linksys E8450 aka. Belkin RT3200 comes with a rather fresh brand
of SPI NAND storage. Add support for it to the nandx driver in
arm-trusted-firmware-mediatek, so we can boot from that chip.
