This patch adds support for the Ubiquiti EdgeRouter X-SFP and
improves support for the EdgeRouter X (PoE-passthrough).
Specification:
- SoC: MediaTek MT7621AT
- Flash: 256 MiB
- RAM: 265 MiB
- Ethernet: 5 x LAN (1000 Mbps)
- UART: 1 x UART on PCB (3.3V, RX, TX, GND) - 57600 8N1
- EdgeRouter X:
- 1 x PoE-Passtrough (Eth4)
- powered by Wallwart or passive PoE
- EdgeRouter X-SFP:
- 5 x PoE-Out (24V, passive)
- 1 x SFP (unknown status)
- powered by Wallwart (24V)
Doesn't work:
* SoC has crypto engine but no open driver.
* SoC has nat acceleration, but no open driver.
* This router has 2MB spi flash soldered in but MT
nand/spi drivers do not support pin sharing,
so it is not accessable and disabled. Stock
firmware could read it and it was empty.
Installation
via vendor firmware:
- build an Initrd-image (> 3MiB) and upload the factory-image
- initrd can have luci-mod-failsafe
- flash final firmware via LuCI / sysupgrade on rebooted system
via TFTP:
- stop uboot into tftp-load into option "1"
- upload factory.bin image

Fix a typo in mt7621.dtsi compatible string. Disable spi, sdhci and pci
in mt7621.dtsi and enable the nodes in the indiviual board dts files.
The nodes require further device specific configuration anyway.
Remove the m25p80@0 spi child node from mt7621.dtsi and add the
chunked-io parameter to the individual board dts files. Fix the spi
flash compatible string for the WNDR3700V5.
Drop the mt7621-eval-board compatible string for all boards which are
not the eval board.
Drop the linux,modalias parameter from spi flash node.
Remove the xhci node from board files, it is already enabled in dtsi.
Disable xhci for boards not having usb ports populated.

Add node aliases to dtsi files.
Reword dts files so they're more in-line with upstream.
Fix some more warnings and errors reported by dtc

This router is based on MT7621 SoC, no wifi, no usb, nand.
Works:
* Boots.
* Ethernet.
* Switch.
* Button (reset).
* Flashing OpenWrt from stock firmware.
* Upgrading OpenWrt.
Doesn't work:
* No GPIO leds. All leds are controlled by switch,
but stock firmware was able to control them.
* SoC has crypto engine but no open driver.
* SoC has nat acceleration, but no open driver.
* This router has 2MB spi flash soldered in but MT
nand/spi drivers do not support pin sharing,
so it is not accessable and disabled. Stock
firmware could read it and it was empty.
* PoE out.
Router has serial pins populated. If looking at the top
of the router, then counting from Eth sockets pins go as:
'GND, RX, TX, GND'. 3.3v, 57600.
U-boot bootloader supports tftpboot, controlled from serial.
This router has two kernel partitions: 'live' and 'backup'.
They are swapped during flashing (on both stock and OpenWrt).
Active partition is controlled by a flag in a factory partition.
U-boot has custom command to switch active kernel partition.
Kernel partitions are 'bare flash' 3MB. Stock bootloader has
no UBI support. Stock rootfs is UBIFS.
Flashing procedure.
Stock firmware uses custom kernel patch to mount squashfs
from a file that is located on UBIFS volume. This makes wiping
out this volume from within stock firmware difficult.
Instead this patch builds image that is flashable by stock firmware
and contains initrams image (with minimal set of packages
to fit into kernel partition). Once this is flashed one can reboot
into initramfs OpenWrt and use sysupgrade to flash OpenWrt including
rootfs into nand.
Note: factory image is only built if initramfs image is enabled.
