Initial support for MT7620

[Stanislav Galabov]

Hi all,

After talking with Adrian off list we decided to start work on Mediatek/Ralink more recent SoCs with MT7620 instead of MT7621 (Adrian’s board has MT7620 so it’s easier for him to help with the WiFi parts this way).

I’ve done a bit today and I got an MT7620A based board to boot to multi user with root filesystem on USB stick.

If anyone is interested in the patch, it can be found here:

For the moment there is no support for sys/dev/rt (the Ethernet controller) with MT7620. This is going to be left for later.
Next I am planning to work on SPI and PCI so that Adrian can start working on WiFi once I’m done with the SPI part.

I would appreciate it if someone would jump in and help with the if_rt support - this way we’ll have something working quicker hopefully :-)

I would also appreciate feedback for the attached patch...

Best wishes,
Stanislav
