f1c9afd801 ramips: mt7621-dts: mux phy0/4 to gmac1
Mux the MT7530 switch's phy0/4 to the SoC's gmac1 on devices where RGMII2
pins are available. This achieves 2 Gbps total bandwidth to the CPU using
the second RGMII.

The ports called "wan" are muxed where possible. On a minority of devices,
this is not possible. Those cases:

mt7621_ampedwireless_ally-r1900k.dts: lan3
mt7621_ubnt_edgerouter-x.dts: eth0
mt7621_gnubee_gb-pc1.dts: ethblue
mt7621_linksys_re6500.dts: lan1
mt7621_netgear_wac104.dts: lan4
mt7621_tplink_eap235-wall-v1.dts: lan0
mt7621_tplink_eap615-wall-v1.dts: lan0
mt7621_ubnt_usw-flex.dts: lan1

The "wan" port is just what the vendor designated on the board/plastic
chasis of the device. On a technical level, there is no difference between
a lan and wan port on MT7621AT, MT7621DAT and MT7621ST SoCs. Prefer
connecting to WAN via the port described above for these devices to benefit
the feature brought with this patch.

mt7621_d-team_newifi-d2.dts cannot benefit this feature, although it looks
like it should, because the rgmii2 pins are wired to unused components.

Tested on a range of devices documented on the GitHub PR.

9a7e3d170c ramips: add broken-flash-reset for HLK-7621A EvB
This is needed because the HLK-7621 EvB has 32MB of flash,
so it will have to use 4B addressing and the
broken-flash-reset hack has to be used to be able to reboot.

eb00fb8f71 ramips: add support for HiLink HLK-7621A evaluation board
Specifications:
- SoC: MediaTek MT7621AT
- RAM: 256 MB (DDR3)
- Flash: 32 MB SPI NOR 44MHz
- Switch: 1 WAN, 4 LAN (Gigabit)
- LEDs: 1 WAN, 4 LAN (controlled by PHY)
- USB Ports: 1 x USB2, 1 x USB3
- WLAN: 1 x 2.4, 5 GHz 866Mbps (MT7612E)
- Button: 1 button (reset)
- UART Serial: UART1 as console : 57600 baud
- Power: 12VDC, 1A

Installation:
Update openWRT firmware using internal GNUBEE uboot:
https://github.com/gnubee-git/GnuBee-MT7621-uboot

By HTTP: Initial uboot address is http://10.10.10.123, your address
needs to be 10.10.10.x, and mask 255.255.255.0.
By TFTP: Uboot is in client mode, the address of the firmware must
be tftp://10.10.10.3/uboot.bin

Recovery:
Manufacturer provides MTK OpenWrt 14.07 source code, compile then
flash it by uboot.
HLK-7621A is a stamp hole package module for embedded development,
users have to design IO boards to use it.

MAC addresses:
- u-boot-env contains a placeholder address:
  > mtd_get_mac_ascii u-boot-env ethaddr
  03:17:73🆎cd:ef
- phy0 gets a valid-looking address:
  > cat /sys/class/ieee80211/phy0/macaddress
  f8:62:aa:**:**:a8
- Calibration data for &pcie2 contains a valid address, however the
  zeros in the right half look like it's not real:
  8c:88:2b:00:00:1b
- Since it's an evaluation board and there is no solid information
  about the MAC address assignment, the ethernet MAC address is left random.
