[PATCH v3 0/6] 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:
        - change stdout of memtest to make it more beautiful

v3:
	- fix testing of address bus <-- this never worked before
	- put mem_test function into common/memory_test.c
	- fix some comment issues
	- align quietly start and end address
	- fix some newline issues

Alexander Aring (6):
  common: fix codestyle in ALIGN macros
  common: add ALIGN_DOWN macro
  memory: add function address_in_sdram_regions
  memtest: remove memtest command
  common: add mem_test routine
  commands: add new memtest command
