From 8c2ed9bcfbeb7f313b567b25e87effd75e7dc3d6 Mon Sep 17 00:00:00 2001 From: Joel Stanley Date: Mon, 21 Mar 2016 17:22:31 +1030 Subject: [PATCH] arm: Add Aspeed machine Aspeed devices are a common Baseboard Management Controller (BMC) system on chip containing an ARM9 or ARM11 core, off-chip DDR RAM and support for a large number of peripherals. This patch adds basic support for the ast2400 and ast2500 machines, capable of booting to a prompt in QEMU (-M palmetto-bmc), on an Palmetto OpenPower development machine, and on the ast2500 EVB.
