[PATCH 0/2] Add device tree for Asrock Paul IPMI Card

[Anirudh Srinivasan <anirudhsriniv@gmail.com>]

Adds support for Asrock Paul IPMI Card [1], which is an AST2500 based
PCIe card that provides BMC functionality. 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.
