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.
