[PATCH v4 0/2] ARM: dts: aspeed: ASRock Rack X470D4U BMC support

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
