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

[Anirudh Srinivasan <anirudhsriniv@gmail.com>]

Adds support for Asus IPMI Card [1], which is a PCIe card with an
AST2600 on it that provides BMC functionality to any host without an
onboard BMC as long as it has a PCIe slot.

Currently supported functionality includes UART, NIC, booting from SPI,
KVM functionality(usb gadget for host, reading VGA framebuffer from
host) and LED/Power Control via GPIOs. This functionality has been
tested on an OpenBMC build available here [2]. This requires a modified
u-boot device tree [3], which I can also submit if needed.

The card supports some additional functionality in it's stock firmware
like fan headers with fan speed control, host bios flashing via SPI, PSU
monitoring via an SMBUS connector, a custom ASUS SMBUS connector to talk
to select ASUS motherboards that support it and exposing a IPMI device
via PCIe to the host. These are unsupported at the moment.
