This series adds support for bootmem to the DT core code and removes the
remaining arch specific early_init_dt_alloc_memory_arch implementations.

Compile tested only on arm64, mips, x86, and xtensa.

memblock_virt_alloc() works for both memblock and bootmem, so use it and
make early_init_dt_alloc_memory_arch a static function. The arches using
bootmem define early_init_dt_alloc_memory_arch as either:

__alloc_bootmem(size, align, __pa(MAX_DMA_ADDRESS))

or:

alloc_bootmem_align(size, align)

Both of these evaluate to the same thing as does memblock_virt_alloc for
bootmem. So we can disable the arch specific functions by making
early_init_dt_alloc_memory_arch static and they can be removed in
subsequent commits.

Now that the DT core code handles bootmem arches, we can remove the cris
specific early_init_dt_alloc_memory_arch function. As the default
early_init_dt_add_memory_arch just does a WARN, we can just remove the
entire devicetree.c file.

early_init_dt_add_memory_arch can be used too now that xtensa switched to
memblock.

This series adds support for bootmem to the DT core code and removes the 
remaining arch specific early_init_dt_alloc_memory_arch implementations.

Compile tested only on arm64, mips, x86, and xtensa.

Rob

Rob Herring (7):
  of/fdt: use memblock_virt_alloc for early alloc
  cris: remove arch specific early DT functions
  metag: remove arch specific early DT functions
  mips: remove arch specific early_init_dt_alloc_memory_arch
  nios2: remove arch specific early_init_dt_alloc_memory_arch
  x86: remove arch specific early_init_dt_alloc_memory_arch
  xtensa: remove arch specific early DT functions
