Ralink/MediaTek support progress

[Stanislav Galabov]

Hi all,

I’ve made quite a bit of progress with support for Ralink/Mediatek chipsets with FDT.
Currently I am able to boot MT7620, RT3050, RT5350 and (since half an hour, with only UART and interrupts for now) RT3883.

I’m working on github and the branch in question is:
https://github.com/sgalabov/freebsd/tree/local/sgalabov_mtk

I’d appreciate any comments on what I’ve done so far. My work is currently mostly concentrated in sys/mips/mtk and I’ve left sys/mips/rt305x intact for now.

Going forward, I’m planning on working on unified PCI support for the different SoCs and unified if_rt (ethernet) support.
After that I’ll work on adding other SoCs as well. The target remains the same: have USB, Ethernet, GPIO, PCI/PCIe (where applicable), SPI, Switch for the following SoCs:
RT3050, RT3052, RT5350, RT3352, RT3662, RT3883, RT6856, MT7620, MT7621, MT7628, MT7688.

Any help in getting my hands on MT7628 and MT7688 boards will be appreciated, I have the rest.
Any help in getting programming manuals and/or datasheets for RT6856 and MT7688 would be appreciated too. :-)

Best wishes,
Stanislav
