[OpenBIOS] [PATCH 0/6] Revised OFMEM patches in preparation for SPARC32 OFMEM patches v3

[Mark Cave-Ayland]

Here are the OFMEM changes required in order to migrate SPARC32 over to OFMEM.

v3: 
Rename ofmem_malloc_align() to ofmem_posix_memalign() and match with posix_memalign() API.

v2: 
Revised based upon mailing list comments.

v1: 
Initial implementation.

Mark Cave-Ayland (6):
  Fix alignment of memory allocated by OFMEM's ofmem_malloc().
  Introduce ofmem_posix_memalign() function for arbitrary alignment.
  Introduce va2pa() and pa2va() functions for PPC for subsequent use by
    OFMEM.
  Alter ofmem_posix_memalign() so that the resulting pointer is aligned
    for both physical and virtual addresses.
  Introduce ofmem_arch_get_phys_top() for specifying the top of
    physical memory in OFMEM.
  Change OFMEM to allocate memory from the top of RAM downwards.
