mediatek: MERCUSYS MR90X v1: add OpenWrt U-Boot (UBI) layout
This commit adds OpenWrt U-Boot (UBI) layout support for MERCUSYS MR90X
v1.
Stock U-Boot UBI size: 50 MiB
OpenWrt U-boot UBI size: 126 MiB
Install
-------
1. Perform steps 1-14 of the OpenWrt installation guide (use OpenWrt
initramfs-recovery.itb instead of initramfs-kernel.bin at the step 10,
12 and 14).
Link: https://openwrt.org/toh/mercusys/mr90x_v1#installation
2. Make backups:
```
cat /dev/mtd0 > /tmp/boot.bin
cat /dev/mtd5 > /tmp/tp_data.bin
```
Copy /tp_data dir content, /tmp/boot.bin and /tmp/tp_data.bin and to
your PC using scp. You can also backup the remaining partititons. Copy
backups to a safe place, they are required for the next steps and stock
firmware recovery.
3. Reboot to OpenWrt initramfs:
```
reboot
```
4. Copy OpenWrt ubi-bl31-uboot.fip, ubi-preloader.bin,
ubi-squashfs-sysupgrade.itb and MT7986_EEPROM.bin, default-mac (from
/tp_data backup) to the /tmp folder of the router using scp.
5. Prepare UBI:
```
ubidetach -p /dev/mtd3; ubiformat /dev/mtd3 -y; ubiattach -p /dev/mtd3
ubimkvol /dev/ubi0 -N fip -t static -s 1MiB
ubiupdatevol /dev/ubi0_0 /tmp/ubi-bl31-uboot.fip
ubimkvol /dev/ubi0 -N ubootenv -s 0x1f000
ubimkvol /dev/ubi0 -N ubootenv2 -s 0x1f000
```
6. Install kmod-mtd-rw and unlock partitions:
```
opkg update && opkg install kmod-mtd-rw
insmod mtd-rw i_want_a_brick=1
mtd unlock boot
mtd unlock bl2
mtd unlock factory
```
7. Prepare "factory" partition:
```
dd if=/dev/zero bs=$((0x8000)) count=1 | tr '\000' '\377' > /tmp/factory.bin
dd if=/tmp/MT7986_EEPROM.bin of=/tmp/factory.bin conv=notrunc
dd if=/tmp/default-mac >> /tmp/factory.bin
```
8. Write "factory" partition:
```
mtd erase factory
mtd write /tmp/factory.bin factory
```
9. Write preloader partition:
```
mtd erase bl2
mtd write /tmp/ubi-preloader.bin bl2
```
10. Write OpenWrt sysupgrade image:
```
sysupgrade -n /tmp/ubi-squashfs-sysupgrade.itb
```
Recovery
--------
1. Place OpenWrt initramfs-recovery.itb image (with original name) on the
tftp server (IP: 192.168.1.254).
2. Press "reset" button and power on the router. After ~10 sec release the
button.
3. Use OpenWrt initramfs system for recovery.
BL2 and FIP recovery
--------------------
Use mtk_uartboot and UART connetion if BL2 or FIP in UBI is destroyed:
Link: https://github.com/981213/mtk_uartboot
Link: https://openwrt.org/toh/mercusys/mr90x_v1#serial
Return to stock:
----------------
1. Copy "boot" partition backup (boot.bin) to the /tmp dir of the router
using scp.
2. Install kmod-mtd-rw:
```
opkg update && opkg install kmod-mtd-rw
```
3. Restore stock U-Boot:
```
insmod mtd-rw i_want_a_brick=1
mtd unlock boot
mtd erase boot
mtd write /tmp/boot.bin boot
```
4. Erase UBI and reboot:
```
mtd erase ubi
reboot
```
5. Open U-Boot web recovery, upload stock firmware image and start
upgrade.
Link: http://192.168.1.1
6. Complete steps 1-9 of the OpenWrt installation guide to get root
rights.
Link: https://openwrt.org/toh/mercusys/mr90x_v1#installation
7. Upload "tp_data" partition backup (tp_data.bin) to the /tmp folder of
the router using scp.
8. Restore stock calibrations:
```
mtd write /tmp/tp_data.bin tp_data
reboot
```
9. Perform "factory restore" via stock firmware web interface.

mediatek: fiilogic: device tree switch@1f fix
Quite a few `fiilogic` devices use the `mt7531` switch.
Some of them have a DT node that looks like:
```
switch: switch@0 {
compatible = "mediatek,mt7531";
reg = <31>;
...
};
```
This commit changes the DT node name to `switch@1f`.

mediatek: fix the name of buswidth to bus-width
Fix the issue of dts buswidth cannot be applied properly with spi driver. Fix the name of buswidth to bus-width in dts in order to fit the format in linux spi kernel[1] so that spi-tx-bus-width & spi-rx-bus-width can be parsed properly.

Serial console (UART)
---------------------
V
+-------+-------+-------+-------+
| +3.3V | GND | TX | RX |
+---+---+-------+-------+-------+
|
+--- Don't connect
The R3 (TX line) and R6 (RX line) are absent on the PCB. You should
solder them or solder the jumpers.
Installation (UART)
-------------------
1. Place OpenWrt initramfs image on tftp server with IP 192.168.1.2
2. Attach UART, switch on the router and interrupt the boot process by
pressing 'Ctrl-C'
3. Load and run OpenWrt initramfs image:
tftpboot initramfs-kernel.bin
bootm
4. Once inside OpenWrt, set / update env variables:
fw_setenv baudrate 115200
fw_setenv bootargs "ubi.mtd=ubi0 console=ttyS0,115200n1 loglevel=8 earlycon=uart8250,mmio32,0x11002000 init=/etc/preinit"
fw_setenv fdtcontroladdr 5ffc0e70
fw_setenv ipaddr 192.168.1.1
fw_setenv loadaddr 0x46000000
fw_setenv mtdids "spi-nand0=spi-nand0"
fw_setenv mtdparts "spi-nand0:2M(boot),1M(u-boot-env),50M(ubi0),50M(ubi1),8M(userconfig),4M(tp_data)"
fw_setenv netmask 255.255.255.0
fw_setenv serverip 192.168.1.2
fw_setenv stderr serial@11002000
fw_setenv stdin serial@11002000
fw_setenv stdout serial@11002000
fw_setenv tp_boot_idx 0
5. Run 'sysupgrade -n' with the sysupgrade OpenWrt image
Installation (without UART)
---------------------------
1. Login as root via SSH (router IP, port 20001, password - your web
interface password)
2. Open for editing /etc/hotplug.d/iface/65-iptv (e.g., using WinSCP and
SSH settings from the p.1)
3. Add a newline after "#!/bin/sh":
telnetd -l /bin/login.sh
4. Save "65-iptv" file
5. Toggle "IPTV/VLAN Enable" checkbox in the router web interface and
save
6. Make sure that telnetd is running:
netstat -ltunp | grep 23
7. Login via telnet to router IP, port 23 (no username and password are
required)
8 Upload OpenWrt "initramfs-kernel.bin" to the "/tmp" folder of the
router (e.g., using WinSCP and SSH settings from the p.1)
9. Stock busybox doesn't contain ubiupdatevol command. Hence, we need to
download and upload the full version of busybox to the router. For
example, from here:
https://github.com/xerta555/Busybox-Binaries/raw/master/busybox-arm64
Upload busybox-arm64 to the /tmp dir of the router and run:
in the telnet shell:
cd /tmp
chmod a+x busybox-arm64
10. Check "initramfs-kernel.bin" size:
du -h initramfs-kernel.bin
11. Delete old and create new "kernel" volume with appropriate size
(greater than "initramfs-kernel.bin" size):
ubirmvol /dev/ubi0 -N kernel
ubimkvol /dev/ubi0 -n 1 -N kernel -s 9MiB
12. Write OpenWrt "initramfs-kernel.bin" to the flash:
./busybox-arm64 ubiupdatevol /dev/ubi0_1 /tmp/initramfs-kernel.bin
13. u-boot-env can be empty so lets create it (or overwrite it if it
already exists) with the necessary values:
fw_setenv baudrate 115200
fw_setenv bootargs "ubi.mtd=ubi0 console=ttyS0,115200n1 loglevel=8 earlycon=uart8250,mmio32,0x11002000 init=/etc/preinit"
fw_setenv fdtcontroladdr 5ffc0e70
fw_setenv ipaddr 192.168.1.1
fw_setenv loadaddr 0x46000000
fw_setenv mtdids "spi-nand0=spi-nand0"
fw_setenv mtdparts "spi-nand0:2M(boot),1M(u-boot-env),50M(ubi0),50M(ubi1),8M(userconfig),4M(tp_data)"
fw_setenv netmask 255.255.255.0
fw_setenv serverip 192.168.1.2
fw_setenv stderr serial@11002000
fw_setenv stdin serial@11002000
fw_setenv stdout serial@11002000
fw_setenv tp_boot_idx 0
14. Reboot to OpenWrt initramfs:
reboot
15. Login as root via SSH (IP 192.168.1.1, port 22)
16. Upload OpenWrt sysupgrade.bin image to the /tmp dir of the router
17. Run sysupgrade:
sysupgrade -n /tmp/sysupgrade.bin
Recovery
--------
1. Press Reset button and power on the router
2. Navigate to U-Boot recovery web server (http://192.168.1.1/) and
upload the OEM firmware
Recovery (UART)
---------------
1. Place OpenWrt initramfs image on tftp server with IP 192.168.1.2
2. Attach UART, switch on the router and interrupt the boot process by
pressing 'Ctrl-C'
3. Load and run OpenWrt initramfs image:
tftpboot initramfs-kernel.bin
bootm
4. Do what you need (restore partitions from a backup, install OpenWrt
etc.)
Stock layout
------------
0x000000000000-0x000000200000 : "boot"
0x000000200000-0x000000300000 : "u-boot-env"
0x000000300000-0x000003500000 : "ubi0"

0x000006700000-0x000006f00000 : "userconfig"
0x000006f00000-0x000007300000 : "tp_data"
ubi0/ubi1 format
----------------
U-Boot at boot checks that all volumes are in place:
+-------------------------------+
| Volume Name: uboot Vol ID: 0|
| Volume Name: kernel Vol ID: 1|
| Volume Name: rootfs Vol ID: 2|
+-------------------------------+
MAC addresses
-------------
+---------+-------------------+-----------+
| | MAC | Algorithm |
+---------+-------------------+-----------+
| label | 00:eb:xx:xx:xx:be | label |
| LAN | 00:eb:xx:xx:xx:be | label |
| WAN | 00:eb:xx:xx:xx:bf | label+1 |
| WLAN 2g | 00:eb:xx:xx:xx:be | label |
| WLAN 5g | 00:eb:xx:xx:xx:bd | label-1 |
+---------+-------------------+-----------+
label MAC address was found in UBI partition "tp_data", file
"default-mac". OEM wireless eeprom is also there (file
"MT7986_EEPROM.bin").
