mainboard: Add ASRock H110M-DVS
This board is compatible with Intel Skylake and Kaby Lake generation
processors. This patch contains the minimum configuration for booting
and stable operation of the Ubuntu OS (18.04.1, Linux kernel 4.15).
It is based on Intel RVP8 mainboard.
Intel Kaby Lake FSP 3.6.0 is used to initialize CPU and PCH.
Graphics init with libgfxinit.
Works:
- Integrated graphics (only DVI port, tested with 1920x1080);
- PEG x16 (FSP must be configured with BCT to enable PEG);
- all PCIe x1 slots;
- all USB and SATA ports;
- SuperIO COM port for console;
- onboard audio.
TODO:
- other SuperIO functions;
- onboard network chip;
- suspend and resume;
- documentation.
Tested on Intel Core i5-6600 processor with Seabios (rel-1.12.0-10-
g171fc89) and Tianocore/edk2 (vUDK2018-8-ge6eccfc) as a payload.
