[PATCH] mediatek: filogic: add support for GatoNetworks GDSP

The GatoNetworks GDSP is a re-branded version of the R5000 5G Industrial
router from Yinghua technologies.
The re-branded device comes with OpenWrt preinstalled, and an OpenWrt-based
U-Boot bootloader version. The flash layout has been kept compatible with the
OpenWrt version found on the stock device, making sysupgrade possible.
Specifications:
SOC: Mediatek MT7981BA
RAM: 256MB
Flash: SPI-NOR 32 MiB (Winbond W25Q256)
WLAN: MT7976CN DBDC AX Wi-Fi
Switch: MT7531AE (4x LAN Gigabit ports, 1x WAN Gigabit port)
5G: Quectel RM520N modem
Watchdog: an external WDT connected to GPIO 6 is present and always running;
the builtin Mediatek watchdog is also present and effective, but
not used at the moment.
This porting has been tested only with 1x 5G modems installed (the device
supports up to two).
Installation:
Installation is possible via sysupgrade both in the stock device and
re-branded version (requiring -F and -n in the former case).
OpenWrt-based U-Boot Bootloader installation
--------------------------------------------
The firmware flashed at manifacturing time in the re-branded device will
flash an OpenWrt-based U-Boot bootloader with some extra recovery features
(see [1]).
To update the bootloader, you need to install the mtd-rw module and
insmod it:
insmod mtd-rw i_want_a_brick=1
Then update relevant flash partitions:
mtd erase u-boot-env
mtd erase BL2
mtd erase FIP
mtd write openwrt-mediatek-filogic-gatonetworks_gdsp-preloader.bin BL2
mtd write openwrt-mediatek-filogic-gatonetworks_gdsp-bl31-uboot.fip FIP
And reboot, making sure all previous commands ran succesfully.
If something goes wrong, you can recover your device via the mtk_uartboot
tool.
In my testing, it was possible to start the process even without (un)-plugging
the device, may be handy for remote recovery.
U-Boot Recovery
---------------
This procedure has been tested only with the OpenWrt-based U-boot bootloader.
Assign your system static IP address 192.168.1.1 and start a TFTP server. The
device will look for an initramfs image named
openwrt-mediatek-filogic-gatonetworks_gdsp-initramfs-kernel.bin
(so you may use openwrt/bin/targets/mediatek/filogic as root dir for your
TFTP server).
Power on the device while keeping the reset button pressed, until you see
a TFTP request from 192.168.1.10. Your environment will be restored to it's
default state.
Notes
-----
[1]: the OpenWrt-based U-Boot bootloader you will find installed in the
device is configured to request for the initramfs image via TFTP for
$gdsp_tftp_tries times before trying normal boot from NOR flash.
Setting this U-Boot environment variable to 0x0 will disable the feature,
which is not implemented in this patch.
[2]: the exposed UART port is connected to ttyS1; the ttyS0 console port s not
exposed.
[3]: the provided bootloader environment has no provision for operating on
BL2 and the FIP partitions. This is an intentional choice to make it
(slightly) more difficult to brick the device.
