The vendor u-boot knows nothing about UBI, and we used to have a
fixed-size kernel partition for vendor u-boot and UBI for rootfs.
However, that fixed partition becomes too small eventually, and
expanding it requires complicated procedure.
This commit changed the flash layout and added a second u-boot
where the kernel supposed to be.
Now the vendor u-boot chainloads our mainline u-boot, and our
u-boot reads kernel+rootfs from UBI, verifies it, and boot
into OpenWrt.
There are two possible ways to convert from the old fw:
Flash the factory image using mtd (provided by @rany2):
mount -o remount,ro /
mount -o remount,ro /overlay
cd /tmp
dd if=factory.bin bs=1M count=4 | mtd write - kernel
dd if=factory.bin bs=1M skip=4 | mtd -r write - ubi
Or, flash the 2nd u-boot via mtd and upload the firmware
to the 2nd u-boot using tftp:
1. prepare a tftp server at 192.168.1.254 to serve the
sysupgrade image:
openwrt-mediatek-mt7622-xiaomi_redmi-router-ax6s-squashfs-sysupgrade.itb
2. upload the ubi-loader.itb to OpenWrt /tmp, and flash it to
the old kernel partition:
mtd -r write openwrt-mediatek-mt7622-xiaomi_redmi-router-ax6s-ubi-loader.itb
3. The router should reboot and flash the sysupgrade image via TFTP.
Procedure for flashing from vendor firmware shouldn't change.

Most mt7622 devices use the mt7531 switch, which have been
switched to dsa driver for a long time. So use dsa as the
default configuration and configure these rtl8367s devices
separately. This reduces the amount of code.

Move fip and factory into UBI static volumes.
Use fitblk instead of partition parser.
!! RUN INSTALLER FIRST !!
Existing users of previous OpenWrt releases or snapshot builds will
have to **re-run the updated installer** before upgrading to firmware
after this commit.
DO NOT flash or run even just the initramfs image unless you have
run the updated installer which moves the content of the 'factory'
partition into a UBI volume.
tl;dr: DON'T USE YET!

Flashing via uBoot:
- Open the case, connect to the UART console
- Set your IP address to 10.10.10.3, subnet mask 255.255.255.0. Connect to one of the LAN interfaces of the router
- Run a tftp server which provides openwrt-mediatek-mt7622-dlink_eagle-pro-ai-r32-initramfs-kernel.bin.
- You can rename the file to iverson_uImage (no extension), then you don't have to enter the whole file name in uboot later.
- Power on the device and select "1. System Load Linux to SDRAM via TFTP." in the boot menu
- Enter image file, tftp server IP and device IP (if they differ from the default).
- TFTP download to RAM will start. After a few seconds OpenWrt initramfs should start
- The initramfs is accessible via 192.168.1.1, change your IP address accordingly (or use multiple IP addresses on your interface)
- Create a backup of the Kernel1 partition, this file is required if a revert to stock should be done later
- Perform a sysupgrade using openwrt-mediatek-mt7622-dlink_eagle-pro-ai-r32-squashfs-sysupgrade.bin
- Reboot the device. OpenWrt should start from flash now
Revert back to stock using the Recovery Web Interface:
- Set your IP address to 192.168.0.10, subnetmask 255.255.255.0

- Compile a binary from the downloaded file, e.g. gcc m32-firmware-util.c -lcrypto -o m32-firmware-util
- Run ./m32-firmware-util R32 --DecryptFactoryImage <OriginalFirmware> <OutputFile>
- Example for firmware R32A1_FW103B01: ./m32-firmware-util R32 --DecryptFactoryImage R32A1_FW103B01.bin R32A1_FW103B01.decrypted.bin
Revert back to stock using uBoot:
- Open the case, connect to the UART console
- Set your IP address to 10.10.10.3, subnet mask 255.255.255.0. Connect to one of the LAN interfaces of the router
- Run a tftp server which provides the previously created backup of the Kernel1 partition.
- You can rename the file to iverson_uImage (no extension), then you don't have to enter the whole file name in uboot later.
- Power on the device and select "2. System Load Linux Kernel then write to Flash via TFTP." in the boot menu
- Enter image file, tftp server IP and device IP (if they differ from the default).
- TFTP download to FLASH will start. After a few seconds the stock firmware should start again
There is also an image openwrt-mediatek-mt7622-dlink_eagle-pro-ai-r32-a1-squashfs-tftp.bin which can directly be flashed via U-Boot and TFTP.
It can be used if no backup of the Kernel1 partition is reuqired.
Flahsing via OEM web interface is currently not possible, the OEM images are encrypted. Creating images is only possible manually at the moment.
The support for the M32/R32 already includes support for flashing from the OEM web interface:
- The device tree contains both partitions (Kernel1 and Kernel2) with conditions to select the correct one based on the kernel command line
- The U-Boot variable "boot_part" is set accordingly during startup to finish the partition swap after flashing from the OEM web interface
- OpenWrt sysupgrade flashing always uses the partition where it was initially flashed to (no partition swap)

If the board comes up with OpenWrt that means that the bootloader is
recent enough and knows about the new device tree overlays.
Using /etc/board.d/ is not enough in this case because it doesn't
overwrite existing configuration which may exist (and is fine to exist)
if the user updated with 'sysupgrade -F *.itb' and has kept
configuration. They would still need to manually set compat_version
even though the fact that the bootloader env has been updated can be
implied by the fact that the system has started.
Hence we can always set compat_version=1.1 for those two boards using
uci-defaults.

Known Limitations:
* The 2.5G WAN port labeled 'wan' only works for speeds up to 1G at the
moment. If connected to a multi-gig port the speed has to be manually
set to 1G/full either for the switch port or in OpenWrt. For example
add the following to /etc/rc.local to set it on boot:
/usr/sbin/ethtool -s wan speed 1000 duplex full

**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!

The vendor flash layout of the Linksys E8450 is problematic as it uses
the SPI-NAND chip without any wear-leveling while at the same time
wasting a lot of space for padding.
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 :)

Opening the case
----------------
Opening the case is not a nice task, as itis glued together. Insert a
flat knife between the front and back casing below the ethernet port.
Open up a gap this way and insert a flat scredriver, remove the knife.
Work your way around the casing by applying force to seperate the front
and back casing. This losens the glue and opens the plastic clips. Be
gentle, as these clips are very cheap and break quickly.
Installation
------------
1. Connect to the booted device at 192.168.1.20 using username/password
"ubnt".
2. Transfer the OpenWrt sysupgrade image to the device using SCP.
3. Check the mtd partition number for bs / kernel0 / kernel1
$ cat /proc/mtd
4. Set the bootselect flag to boot from kernel0
$ dd if=/dev/zero bs=1 count=1 of=/dev/mtdblock6
5. Write the OpenWrt sysupgrade image to both kernel0 as well as kernel1
$ dd if=openwrt.bin of=/dev/mtdblock8
$ dd if=openwrt.bin of=/dev/mtdblock9
6. Reboot the device. It should boot into OpenWrt.

This splits some base-files across subtargets, as done previously
on ath79 and ramips and also introduced for mt7629 subtarget here
already. Most of the existing base-files content is specific to
mt7623.
While at it, apply the following fixes:
- Remove lots of trailing whitespaces
- Remove wildcard on unielec,u7623-02-emmc-512m
- Remove inconsistent quotation marks in cases
