Subject: [PATCH v2 0/2] Add device tree for ASRock Rack ALTRAD8 BMC

The ASRock Rack ALTRAD8 BMC is an Aspeed AST2500-based BMC for the
ALTRAD8UD-1L2T and ALTRAD8UD2-1L2Q boards with an Ampere Altra
processor. The BMC runs OpenBMC.

These patches add a device tree and binding for the BMC.

**Changes between v1 and v2**

- Reordered nodes to be in alphabetical order.
- Removed status lines.
- Fixed naming.

There are still several warnings from
make CHECK_DTBS=y ARCH=arm W=1 aspeed/aspeed-bmc-asrock-altrad8.dtb
I believe the only one which is reporting an issue in my dts file (as opposed
to included files) is the first, and that's because the code partition contains
the TF-A and UEFI areas. I couldn't see a way to suppress it.
