[PATCH 2/2] ARM: dts: aspeed: Add ASRock SPC621D8HM3 BMC

From: Zev Weiss
Date: Tue Nov 14 2023 - 06:28:42 EST

This is a Xeon board broadly similar (aside from CPU vendor) to the
already-support romed8hm3 (half-width, single-socket, ast2500). It
doesn't require anything terribly special for OpenBMC support, so this
device-tree should provide everything necessary for basic
functionality with it.
