[POWERPC] Re-organize Kconfig code for 4xx in arch/powerpc
Now that we always take a device tree in arch/powerpc, there's no good reason not to allow a single kernel to support multiple embedded 4xx boards - the correct platform code can be selected based on the device tree information. Therefore, this patch re-arranges the 4xx Kconfig code to allow this. In addition we: - use "select" instead of depends to configure the correct config options for specific 4xx CPUs and workarounds, which makes the information about specific boards and CPUs less scattered. - Some old, unused (in arch/powerpc) config options are removed: WANT_EARLY_SERIAL, IBM_OCP, etc. Signed-off-by: David Gibson <dwg@au1.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
