[POWERPC] 85xx: SBC8548 - Add flash support and HW Rev reporting
The following adds local bus, flash and MTD partition nodes for
sbc8548. As well, a compatible field for the soc node, so that
of_platform_bus_probe() will pick it up.
Something that is provided through this newly added epld node
is the Hardware Revision which is now being utilized.
