[Qemu-devel] [PULL 15/21] hw/arm: Add palmetto-bmc machine |

From: Andrew Jeffery <address@hidden>
The new machine is a thin layer over the AST2400 ARM926-based SoC[1].
Between the minimal machine and the current SoC implementation there is
enough functionality to boot an aspeed_defconfig Linux kernel to
userspace. Nothing yet is specific to the Palmetto's BMC (other than
using an AST2400 SoC), but creating specific machine types is preferable
to a generic machine that doesn't match any particular hardware.
