The supported functionality is similar to the Asus Kommando IPMI Card, support for which was sent previously [2]. Supported functionality includes UART, Booting from Primary SPI, Networking, KVM functionality (USB Gadget and Video Engine), LEDs and GPIO Power control. Complete BMC functionality has been tested on an OpenBMC build available here [3], relying on this kernel branch [4]. For some reason, the Video Engine isn't always stable when the host PC's video output goes black/changes resolution, resulting in a hang and a subsequent reset of the Aspeed. Applying this patch [5] from the Aspeed vendor kernel seems to fix this issue. This doesn't require any changes to the device tree for this device though, so I think it shouldn't affect this patch series.
