mb/hardkernel/odroid-h4: Add support for ODROID-H4 series
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 Change-Id: I7e0d395ba3d15dfcf6d47a222b90499ca371e4eb Signed-off-by: David Milosevic <David.Milosevic@9elements.com> Signed-off-by: Angel Pons <th3fanbus@gmail.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/83979 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Arthur Heymans <arthur@aheymans.xyz>
