[PATCH v2 0/8] add new memtest command

[Alexander Aring]

The new memtest command supports to enable or disable
caching during testing(only arm architecture) and
skipping barebox regions for avoid a barebox killing,
if you want to write on barebox allocated regions.

If you run memtest without a argument, memtest will
run on all registered memory banks.

The new memtest command has these arguments:
	-s #ADDRESS [for start address]
	-e #ADDRESS [for end address]
	-i #ITER [for numbers of iterations]
	-c [don't disable caching]
	-b [do bus testing only]

v2:
	- remove adding whitespaces in linkerscript file
		and change position in of '_sdata'
		in ppc lds files.
	- remove -1 calculation in linkerscript files
		which is wrong.
	- split remap_range patch into three other patches:
		- mmu: add getters for pte cache flags
		- arm-mmu: move PAGE_ALIGN macro to common.h
		- common: add PAGE_ALIGN_DOWN macro
	- change stdout of memtest to make it more beautiful

Alexander Aring (8):
  remap_range: make function 'remap_range' global
  mmu: add getters for pte cache flags
  arm-mmu: move PAGE_ALIGN macro to common.h
  common: add PAGE_ALIGN_DOWN macro
  memory: add function address_in_sdram_regions
  barebox-data: add barebox-data sections
  memtest: remove memtest command
  memtest: add rewritten memtest command
