0415aba6a9 uboot-mediatek: add missing 'memory' nodes to downstream boards
Among the patches adding support for MT7988 also came the switch to
use fdtdec_setup_mem_size_base() and no longer rely on CFG_SYS_SDRAM_BASE.
Take care of our downstream boards which did not have a 'memory' node in
their device trees.

42eeb22450 uboot-mediatek: fix factory/reset button
U-Boot commit ea6fdc13595 ("dm: button: add support for linux_code in
button-gpio.c driver") makes it mandatory to specify linux,code for all
buttons. As that broke handling of the reset button in U-Boot with the
update to U-Boot 2023.04, add linux,code for all butons.

50f7c5af4a uboot-mediatek: update to v2023.04
Update to next U-Boot timed release.
Remove now obsolete patch
100-01-board-mediatek-add-more-network-configurations.patch
Default IP addresses are now dealt with in Kconfig, no longer in board-
specific C header files.

Add patches to restore ANSI support in bootmenu which was broken upstream,
always use high-speed mode on serial UART for improved stability and fix
an issue with pinconf not being applied on MT7623 resulting in eMMC
being inaccessible when booting from micro SD card.

In order to keep the size of the bootloader on MT7623 below 512kB remove
some unneeded commands on both MT7623 boards.

Tested on:
 * BananaPi BPi-R2 (MT7623N)
 * BananaPi BPi-R3 (MT7986A)
 * BananaPi BPi-R64 (MT7622A)
 * Linksys E8450 (MT7622B)

1613e3340b uboot-mediatek: add support for Xiaomi Redmi Router AX6000
U-Boot flash instructions:

0. OpenWrt U-Boot does not support stock layout, it comes with recovery
boot support, automatic tftp recovery and never blocks UART.

A new flash layout is introduced, we call it OpenWrt U-Boot layout,
stock flash layout and the old OpenWrt layout are not supported.

During the whole flash procedure, please do not reboot or power off
unless requested explicitly, or you will break your device.

1. Your device should already running OpenWrt.
If not, follow the instructions to flash OpenWrt:
https://github.com/openwrt/openwrt/pull/11115

2. Backup BL2 Nvram Bdata Factory and FIP in case you break something or
in case you want to go back to stock firmware one day.

cat /dev/mtdblock0 > /tmp/BL2.bin
cat /dev/mtdblock1 > /tmp/Nvram.bin
cat /dev/mtdblock2 > /tmp/Bdata.bin
cat /dev/mtdblock3 > /tmp/Factory.bin
cat /dev/mtdblock4 > /tmp/FIP.bin

And save all whose bin files to somewhere safe.

Then backup your configurations, since ubiformat for entire mtd device is
required to create new ubootenv volume for OpenWrt U-Boot.

3. Run the following cmd to boot into an initramfs with the new OpenWrt
U-Boot layout that expand ubi partion to the end of flash:

ubiformat /dev/mtd7 -y -f /tmp/ax6000-ubootmod-initramfs-factory.ubi

4. After boot into initramfs, check mtd partion info.
The ubi partion should be mtd5

root@OpenWrt:~# cat /proc/mtd
dev:    size   erasesize  name
mtd0: 00100000 00020000 BL2
mtd1: 00040000 00020000 Nvram
mtd2: 00040000 00020000 Bdata
mtd3: 00200000 00020000 Factory
mtd4: 00200000 00020000 FIP
mtd5: 07a80000 00020000 ubi

5. Load kmod-mtd-rw to temporarily make the bootloader partions writable.
The kmod-mtd-rw is from the feeds, it is not packed in initramfs-factory
by default.

To install kmod-mtd-rw via opkg:

opkg update && opkg install kmod-mtd-rw

Or, download kmod-mtd-rw.ipk from OpenWrt server and install it manually
e.g:
https://downloads.openwrt.org/snapshots/targets/mediatek/filogic/kmods/
Select your OpenWrt release version and kernel version accordingly.

Load kmod-mtd-rw:
insmod /lib/modules/$(uname -r)/mtd-rw.ko i_want_a_brick=1

6. Run the following cmd to clean all pending crash dumps in pstore,
or OpenWrt U-Boot may boot into NAND recovery or tftp recovery.

rm -f /sys/fs/pstore/*

7. Format ubi and create new ubootenv volume:

ubidetach -p /dev/mtd5; ubiformat /dev/mtd5 -y; ubiattach -p /dev/mtd5
ubimkvol /dev/ubi0 -n 0 -N ubootenv -s 128KiB
ubimkvol /dev/ubi0 -n 1 -N ubootenv2 -s 128KiB

8. This is optional. Skip this if you do not want to have NAND recovery
boot feature offered by OpenWrt U-Boot. Don't worry, you always have
automatic tftp recovery feature enabled.

ubimkvol /dev/ubi0 -n 2 -N recovery -s 10MiB
ubiupdatevol /dev/ubi0_2 /tmp/ax6000-ubootmod-initramfs-recovery.itb

9. Now, flash new U-Boot. Bye-bye ugly stock U-Boot.

mtd write /tmp/ax6000-ubootmod-preloader.bin BL2
mtd write /tmp/ax6000-ubootmod-bl31-uboot.fip FIP

10. Flash the squashfs-sysupgrade.bin as usual:

sysupgrade -n /tmp/ax6000-ubootmod-squashfs-sysupgrade.itb

Enjoy!
