cc00e22029 uboot-mediatek: add TP-Link TL-XDR4288 and TL-XDR608x
TP-Link TL-XDR608x comes with locked vendor loader. Add U-Boot build
for replacement loader for both TL-XDR6086 and TL-XDR6088. The only
difference at U-Boot level is the different filename requested via
TFTP, matching the corresponding OpenWrt build artifacts for each
device.

The TP-Link TL-XDR4288 has the same hardware as the TP-Link TL-XDR6088
except for the wireless part. Also create a uboot for the TP-Link
TL-XDR4288.

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.

00a240e77f uboot-mediatek: fix build for RAVPower RP-WD009
Updating to U-Boot 2023.04 broke the build for the RAVPower RP-WD009
MT7628 board. This was due to upstream conversion of CONFIG_* to CFG_*
which was not applied to our downstream patch adding support for the
RAVPower RP-WD009 device.

Apply CONFIG_* to CFG_* converion analog to what has been done also
for mt7928_rfb upstream.

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!

c2bc1bd99a uboot-mediatek: add support for Bananapi BPi-R3
The Bananapi BPi-R3 board can boot from eMMC, SD card, SPI-NAND and
SPI-NOR, depending on the position of switches controlling the BOOTSEL
bootstrap pins as we as hard-wired chip-select lines. The position of the
chip-select switch SW6 decides whether either SD card or eMMC can be
accessed, SW5 selects either SPI-NAND or SPI-NOR.

Generate U-Boot for all 4 boot options. The SD card version allows
installation to SPI-NAND and SPI-NOR (eMMC cannot be accessed
simultanously with the SD card), the SPI-NAND version allows installation
to eMMC.

uboot-mediatek: several fixes for MT7622
* ! Behavior change !

   Old behavior: If the Reset button is held down during power-on
   do factory reset and try booting recovery from TFTP forever.
   If valid recovery is received via TFTP, write it to flash and boot.

   New behavior: If the Reset button is held down during power-on
   do factory reset, then try TFTP *once*, then try booting on-flash
   recovery, then keep trying via TFTP forever until a valid image is
   received.
   Only if there is no bootable recovery stored on flash, store the
   downloaded recovery. Then boot it.

 * Set loadaddr to 0x48000000 in order to allow booting images larger
   than ~47MB (reported by Oskari Lemmelä). Setting loadaddr to
   0x48000000 gives us 384MB on devices with 512MB RAM, which should be
   more than enough as a maximum size for uImage.FIT to be loaded.

 * Widely unify device-specific default environment in preparation to
   auto-generate it from parameters.

 * backport upstream commit fixing MBR/DOS partitioning

uboot-mediatek: add build for Ubiquiti Networks UniFi 6 LR
Add U-Boot build for the Ubiquiti Networks UniFi 6 LR access point.
This allows updating the bootchain to modern ARM Trusted Firmware 2.4
and U-Boot 2021.04 while keeping as much of the existing flash layout
as possible (u-boot-env, factory and eeprom partitions are retained),
gaining robust recovery vs. production dual-boot mechanism.
Add info for the Winbond W25Q512JV SPI NOR flash used in the device
and wait for GPIOs to settle after reset before checking for reset
button.
I2C connected LED controller is not supported yet.
Writing large amounts of data to SPI flash currently doesn't work due
to watchdog timeout causing reset before data write completes.
