Several devices in mt76x8 subtarget use the following line to set
up wmac in their DTS(I) files:
ralink,mtd-eeprom = <&factory 0x4>
This is strange for several reasons:
- They should use mediatek,mtd-eeprom on this SOC
- The caldata is supposed to start at 0x0
- The parent DTSI mt7628an.dtsi specifies mediatek,mtd-eeprom anyway,
starting from 0x0
- The offset coincides with the default location of the MAC address
in caldata
Based on the comment in b28e94d4bf ("ramips: MiWiFi Nano fixes"),
it looks like the author for this device wanted to actually use
mtd-mac-address instead of ralink,mtd-eeprom. A check on the same
device revealed that actually the MAC address start at offset 4 there,
so the correct caldata offset is 0x0.
Based on these findings, and the fact that the expected location on
this SOC is 0x0, we remove the "ralink,mtd-eeprom = <&factory 0x4>"
statement from all devices in ramips (being only mt7628an anyway).
Thanks to Sungbo Eo for finding and researching this.

(cherry picked from commit 09d38a3bc3)
It's OEM module with 2*26 pin header, similar to LinkIt Smart 7688 or
Vocore2.
Specification:
CPU: MT7628 580 MHz. MIPS 24K
RAM: 64 MB
Flash: 8 MB
WIFI: 802.11n/g/b 20/40 MHz
USB: 1x Port USB 2.0
Ethernet: 5 Port ethernet switch
UART: 2x
Installation: Use the installed uboot Bootloader. Connect a serial cable
to serialport 0. Turn power on. Choose the option: "Load system code
then write to Flash via TFTP". Choose the local device IP and the TFTP
server IP and the file name of the system image. After if the
Bootloader will copy the image to the local flash.
Notes: The I2C Kernel module work not correctly. You can send and
receive data. But the command i2cdetect doesn’t work. FS#845
