From a9a3d60b937acac92690bcafd0c59272f59208fc Mon Sep 17 00:00:00 2001 From: Zev Weiss Date: Wed, 5 Jan 2022 02:17:19 -0800 Subject: [PATCH] ARM: dts: aspeed: Add ASRock ROMED8HM3 BMC This is a half-width, single-socket Epyc server board with an AST2500 BMC. This device tree is sufficient for basic OpenBMC functionality, but we'll need to add a few more devices (as driver support becomes available) before it's fully usable.
