arm: mem_init: use memblock_phys_free() to free DMA memory on SA1111
Patch series "arch, mm: reduce code duplication in mem_init()", v2.
Every architecture has implementation of mem_init() function and some even
more than one. All these release free memory to the buddy allocator, most
of them set high_memory to the end of directly addressable memory and many
of them set max_mapnr for FLATMEM case.
These patches pull the commonalities into the generic code and refactor
some of the mem_init() implementations so that many of them can be just
dropped.
This patch (of 13):
This will help to pull out memblock_free_all() to generic code.
