Add support for the ODROID-H4 family of boards. Tested on an ODROID-H4+
board, but all of them use the same PCB (with different components).
The four SATA ports on the mainboard are provided by an onboard ASMedia
ASM1064B PCIe-to-SATA bridge. Unlike other mainboards in the tree using
an ASMedia ASM1061 or ASM1062 PCIe-to-SATA bridge, the ODROID-H4+ comes
with a SPI flash chip for the ASM1064B and does not seem to have issues
regarding PCIe power management (e.g. ASPM) or unusable SATA AHCI mode.
The ODROID-H4 comes with a single 16 MiB SPI flash chip. The ODROID-H4+
and the ODROID-H4 Ultra feature Dual BIOS, consisting of another 16 MiB
SPI flash chip and a 3-pin header to select between them. The board can
be flashed internally or using a SOIC-8 clip, but the M.2 slot may need
to be empty for the clip to fit.
Working:
- DDR5 SO-DIMM slot
- All SATA ports on ASMedia ASM1064B PCIe-to-SATA controller
- UART to emit spam
- All video outputs (FSP GOP only lights up one output at a time)
- All USB ports (on the Ethernet connectors and on EXT_HDR1)
- M.2 M connector (PCIe only)
- PCIe power management
- Ethernet NICs
- eMMC
- HD audio codec and display audio
- S3 suspend/resume
- SeaBIOS <current version>
- MrChromebox edk2 <current version>
- Super I/O HWM on Linux (using out-of-tree it87 kernel module)
- Booting Arch Linux from NVMe and SATA
- Booting Windows 10 from NVMe
Not working:
- PECI: undocumented protocol and undocumented Super I/O
- Resuming on Windows 10 BSODs with `VIDEO_TDR_FAILURE`
Untested:
- Fan curves: may need to lower the temperature limits a bit
