fd5ced246a mediatek: fix Ubiquiti UniFi 6 LR LED
When adding Kernel 5.10 support, the kernel configuration did not

74f15628dd mediatek: add support for Buffalo WSR-2533DHP2
This adds support for the Buffalo WSR-2533DHP2.

The device uses the Broadcom TRX image format with a special magic. To
be able to boot the images or load them they have to be wrapped with
different headers depending how it is loaded.

There are multiple ways to install OpenWrt on this device.
Boot ramdisk from U-Boot
----------------------------
This will load the image and not write it into the flash.

1. Stop boot menu with "space" key
2. Select "System Load Linux to SDRAM via TFTP."
3. Load this image:
   openwrt-mediatek-mt7622-buffalo_wsr-2533dhp2-initramfs-kernel.bin
4. The system boots the image

Write to flash from U-Boot
-----------------------------
This will load the image over tftp and directly write it into the flash.

1. Stop boot menu with "space" key
2. Select "System Load Linux Kernel then write to Flash via TFTP."
3. Load this image:
   openwrt-mediatek-mt7622-buffalo_wsr-2533dhp2-squashfs-factory-uboot.bin
4. The system writes this image into the flash and boots into it.

Write to flash from Web UI
-----------------------------
This will load the image over over the Web UI and write it into the flash

1. Open the Web UI
2. Go to "管理" -> "ファームウェア更新"
3. Select "ローカルファイル指定" and click "更新実行"
4. Load this image:
   openwrt-mediatek-mt7622-buffalo_wsr-2533dhp2-squashfs-factory.bin
5. The system writes this image into the flash and boots into it.

Specifications
-------------------
* SoC:       MT7622 (4x4 2.4 GHz Wifi)
* Wifi:      MT7615 (4x4 5 GHz Wifi)
* Flash:     Winbond W29N01HZ 128MB SLC NAND
* RAM        256MB

85b1f4d8ca treewide: remove execute bit and shebang from board.d files
So far, board.d files were having execute bit set and contained a
shebang. However, they are just sourced in board_detect, with an
apparantly unnecessary check for execute permission beforehand.

Replace this check by one for existance and make the board.d files
"normal" files, as would be expected in /etc anyway.

Note:

This removes an apparantly unused '#!/bin/sh /etc/rc.common' in

dfa0a38d1f mediatek: rework support for BananaPi BPi-R64
**What's new**

 * Bring support for the Bananapi BPi-R64 to the level desirable for
   a nice hackable routerboard.
 * Use ARM Trusted Firmware A from source. (goodbye binary preloader)
 * Use Das U-Boot from source. (see previous commit)
 * Assemble SD-card image using OpenWrt image-commands.
   (no gen_sd_cruz_foo.sh added, this is not Raspbian)
 * Updated kernel options to support root filesystem.
 * Updated DTS to match OpenWrt LAN ports, known LEDs, buttons, ...
 * Detect root device, handle sysupgrade, config restore, ...
 * Wire up (known) LEDs and buttons in OpenWrt-fashion.
 * Build one set of images from SD-card and eMMC.
 * Hopefully provide a good example of how things can be done right
   from scratch.

**Installation and images**

 * Have an empty SD-card at hand
 * Write stuff to the card, as root (card device is /dev/mmcblkX)
   - write header, gpt, bl2, atf, u-boot and recovery kernel:
     `cat *bpi-r64-boot-sdcard.img *bpi-r64-initramfs-recovery.fit > /dev/mmcblkX`
   - rescan partitions:
     `blockdev --rereadpt /dev/mmcblkX`
   - write main system to production partition:
     `cat *bpi-r64-squashfs-sysupgrade.fit > /dev/mmcblkXp5`

 * Installation to eMMC works using SD-card bootloader via TFTP
   When running OpenWrt of SD-card, issue this to trigger installation
   to eMMC:
   `fw_setenv bootcmd run emmc_init`
   Be prepared to serve the content of bin/targets/mediatek/mt7622 on
   TFTP server address 192.168.1.254.

**What's missing**

 * The red LED is always on, probably a hardware bug.
 * AHCI (probably needs DTS changes)
 * Ship SD-card image ready with every needed for eMMC install.
 * The eMMC has a second, currently unused boot partition. This would
   be ideal to store the WiFi EEPROM and Ethernet MAC address(es).
   @sinovoip ideas?

Thanks to Thomas Hühn @thuehn for providing the hardware!

Use an all-UBI layout instead, storing the kernel+dtb+squashfs in
uImage.FIT standard format in UBI volume 'fit', the read-write
overlay in UBI volume 'rootfs_data' as well as reduntant U-Boot
environments 'ubootenv' and 'ubootenv2', and a 'recovery'
kernel+dtb+initramfs uImage.FIT for dual-boot.

** WARNING **
THIS PROCEDURE CAN EASILY BRICK YOUR DEVICE PERMANENTLY IF NOT CARRIED
OUT VERY CAREFULLY AND EXACTLY AS DESCRIBED!

Step 0

 * Configure your PC to have the static IPv4 address 192.168.1.254/24
 * Provide bin/targets/mediatek/mt7622 via TFTP

Now continue EITHER with step 1A or 1B, depending on your preference
(and on having serial console wired up or not).

Step 1A (Using the vendor web interface (or non-UBI OpenWrt install))

In order to update to the new bootloader and UBI-based firmware,
use the web browser of your choice to open the routers web-interface
accessible on http://192.168.1.1

 * Navigate to
   'Configuration' -> 'Administration' -> 'Firmware Upgrade'

 * Upload the file
    openwrt-mediatek-mt7622-linksys_e8450-ubi-initramfs-recovery.itb
   and proceed with the upgrade.

 * Once OpenWrt comes up, use SCP to upload the new bootloader files to
   /tmp on the router:
    *-mt7622-linksys_e8450-ubi-preloader.bin
    *-mt7622-linksys_e8450-ubi-bl31-uboot.fip

 * Connect via SSH as you will now need to replace the bootloader in
   the Flash.

    ssh root@192.168.1.1
    (the usual warnings)

 * First of all, backup all the flash now:

    for mtd in /dev/mtdblock*; do
     dd if=$mtd of=/tmp/$(basename $mtd);
    done

 * Then use SCP to copy /tmp/mtdblock* from the router and keep them
   safe. You will need them should you ever want to return to the
   factory firmware!

 * Now flow the uploaded files:
    mtd -e /dev/mtd0 write /tmp/*linksys_e8450-ubi-preloader.bin /dev/mtd0
    mtd -e /dev/mtd1 write /tmp/*linksys_e8450-ubi-bl31-uboot.fip /dev/mtd1

   If and only if both writes look like the completed successfully
   reboot the router. Now continue with step 2.

Step 1B (Using the vendor bootloader serial console)

 * Use the serial to backup all /dev/mtd* devices before using the
   stock firmware (you got root shell when connected to serial).

 * Then reboot and select 'U-Boot Console' in the boot menu.

 * Copy the following lines, one by one:

tftpboot 0x40080000 openwrt-mediatek-mt7622-linksys_e8450-ubi-preloader.bin
tftpboot 0x40100000 openwrt-mediatek-mt7622-linksys_e8450-ubi-bl31-uboot.fip
nand erase 0x0 0x180000
nand write 0x40080000 0x0 0x180000
reset

Now continue with step 2

Step 2

Once the new bootchain comes up, the loader will initialize UBI and the
ubootenv volumes. It will then of course fail to find any bootable
volume and hence resort to load kernel via TFTP from server
192.168.1.254 while giving itself the address 192.168.1.1

The requested file is called
openwrt-mediatek-mt7622-linksys_e8450-ubi-initramfs-recovery.itb
and your TFTP server should provide exactly that :)
It will be written to UBI as recovery image and booted.
You can then continue and flash the production OS image, either
by using sysupgrade in the booted initramfs recovery OS, or by using
the bootloader menu and TFTP.

That's it. Go ahead and mess around with a bootchain built almost
completely from source (only DRAM calibration blobs are fitted in bl2,
and the irreplacable on-chip ROM loader remains, of course).
And enjoy U-Boot built with many great features out-of-the-box.

You can access the bootloader environment from within OpenWrt using the
'fw_printenv' and 'fw_setenv' commands. Don't be afraid, once you got
the new bootchain installed the device should be fairly unbrickable
(holding reset button before and during power-on resets things and
allows reflashing recovery image via TFTP)

Special thanks to @dvn0 (Devan Carpenter) for providing amazingly fast
infra for test-builds, allowing for `make clean ; make -j$(nproc)` in
less than two minutes :)

198385b69d mediatek: switch to use seperate ramdisk for initramfs images
MediaTek targets always use U-Boot's modern uImage.FIT format which
allows bundling several blobs into a single file including hashes,
descriptions and more. In fact, we are already using that to bundle
the Flattened Device Tree blob with the kernel on this and many
other targets.
In the same fashion, we can now make use of the newly introduced
support for building seperate ramdisk to uImage.FIT with a dedicated
initrd blob checked and loaded by U-Boot instead of embedding the
cpio archive into the kernel itself.
This allows for having larger ramdisks, choosing ramdisk compression
independently of kernel compression (while only kernel is decompressed
by the bootloader) and for more easily replacing or modifying the
filesystem contained in an initramfs image.
