Subject: [PATCH v2 0/2] ARM: dts: aspeed: ASRock Rack X470D4U BMC support

Hi,

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.

All flavors will use the 32MB flash layout which should prevent unnecessary
complexity of the device tree.

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

Thanks,
Tan

v2:
  - fix led node names [robh]
  - fix missing gfx memory region and other fixable dtbs_check issues [Tan]
