This series adds support for the BMC of the ASRock Rack X470D4U mainboard,
which uses an ASPEED AST2500.

The mainboard exists in three known flavors, the "normal" X470D4U, the
X470D4U2-2T (with 2x10G RJ45) and the X470D4U2/1N1 (an ODM version with
2x1G RJ45 that is now available in retail). The 1N1 version also has a 64MB
BMC SPI by default, but they are all swappable.

There are two device trees, one that has all the config and uses a 32MB
flash layout, and another one called "data64" (similar to facebook-fuji)
that uses the 64MB flash layout.

Please note that this board has been fully reverse-engineered.

Thanks,
Tan
