Subject: [PATCH] android: make persistent_ram based drivers depend on HAVE_MEMBLOCK

m68k doesn't have memblock_reserve, which causes a build failure
with allmodconfig.  Make PERSISTENT_RAM and RAM_CONSOLE depend on
HAVE_MEMBLOCK.

I can't test on m68k, but this disables the options if I remove
HAVE_MEMBLOCK from arm.
