[PATCH v2 0/2] Add device tree for Asus Kommando IPMI Card

[Anirudh Srinivasan]

Adds support for Asus Kommando IPMI Card [1] [2], 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. The model name
Kommando is based off the model description in the vendor fw.

Currently supported functionality includes UART, booting from SPI,
KVM functionality(usb gadget for host, reading VGA framebuffer from
host) and LED/Power Control via GPIOs. NIC support is not included,
requiring additional patches which will be sent later on [3]. The
entire BMC functionality has been tested on an OpenBMC build 
available here [4] (which uses a modified u-boot device tree [5]).

The card supports some additional functionality in it's vendor 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.
