microblaze: clean-up prom.h implicit includes

2013-10-10T01:04:03+00:00

While powerpc is a mess of implicit includes by prom.h, microblaze just
copied this and is easily fixed. Add the necessary explicit includes and
remove unnecessary includes and other parts from prom.h

of: remove early_init_dt_setup_initrd_arch

2013-10-09T16:39:01+00:00

All arches do essentially the same thing now for
early_init_dt_setup_initrd_arch, so it can now be removed.

of: create default early_init_dt_add_memory_arch

2013-10-09T16:38:19+00:00

Create a weak version of early_init_dt_add_memory_arch which uses
memblock. This will unify all architectures except ones with custom
memory bank structs.

of: consolidate definition of early_init_dt_alloc_memory_arch()

2013-08-28T20:18:32+00:00

Most architectures use the same implementation. Collapse the common ones
into a single weak function that can be overridden.

of: Specify initrd location using 64-bit

2013-07-24T10:10:01+00:00

On some PAE architectures, the entire range of physical memory could reside
outside the 32-bit limit.  These systems need the ability to specify the
initrd location using 64-bit numbers.

This patch globally modifies the early_init_dt_setup_initrd_arch() function to
use 64-bit numbers instead of the current unsigned long.

There has been quite a bit of debate about whether to use u64 or phys_addr_t.
It was concluded to stick to u64 to be consistent with rest of the device
tree code. As summarized by Geert, "The address to load the initrd is decided
by the bootloader/user and set at that point later in time. The dtb should not
be tied to the kernel you are booting"

memblock: s/memblock_analyze()/memblock_allow_resize()/ and update users

2011-12-08T18:22:08+00:00

The only function of memblock_analyze() is now allowing resize of
memblock region arrays.  Rename it to memblock_allow_resize() and
update its users.

* The following users remain the same other than renaming.

  arm/mm/init.c::arm_memblock_init()
  microblaze/kernel/prom.c::early_init_devtree()
  powerpc/kernel/prom.c::early_init_devtree()
  openrisc/kernel/prom.c::early_init_devtree()
  sh/mm/init.c::paging_init()
  sparc/mm/init_64.c::paging_init()
  unicore32/mm/init.c::uc32_memblock_init()

* In the following users, analyze was used to update total size which
  is no longer necessary.

  powerpc/kernel/machine_kexec.c::reserve_crashkernel()
  powerpc/kernel/prom.c::early_init_devtree()
  powerpc/mm/init_32.c::MMU_init()
  powerpc/mm/tlb_nohash.c::__early_init_mmu()  
  powerpc/platforms/ps3/mm.c::ps3_mm_add_memory()
  powerpc/platforms/embedded6xx/wii.c::wii_memory_fixups()
  sh/kernel/machine_kexec.c::reserve_crashkernel()

* x86/kernel/e820.c::memblock_x86_fill() was directly setting
  memblock_can_resize before populating memblock and calling analyze
  afterwards.  Call memblock_allow_resize() before start populating.

memblock_can_resize is now static inside memblock.c.
