#     powerpc/32: activate ARCH_HAS_PMEM_API and ARCH_HAS_UACCESS_FLUSHCACHE
#     
#     PPC32 also have flush_dcache_range() so it can also support
#     ARCH_HAS_PMEM_API and ARCH_HAS_UACCESS_FLUSHCACHE without changes.

The function __boot_from_prom() references
the function __init prom_init().
This is often because __boot_from_prom lacks a __init 
annotation or the annotation of prom_init is wrong.
