[PATCH/RFC 0/5] Another try for a new memtest implementation

[Alexander Aring <alex.aring@gmail.com>]

Hi,

this is a new try to get a new memtest implementation into barebox.

I removed the ADDRESS_IN_REGIONS macro, which was a very ugly solution.
The new memtest command used a list and save all unused sdram_regions
of each bank. Then running the mem_test routine on these regions.
After that the memtest command will release the requested sdram_regions.

I removed the start and stop command arguments to make the implementation
easier/understandable and it's not necessary anyway.

Maybe it's better to remove the silent ALIGN and ALIGN_DOWN from the start
and end address in the common mem_test routine, because addresses are already
align.
It is difficult to explain because a end address has the form of 0xXXXXffff
and a ALIGN_DOWN on it with a mask of 3 we have a calculated end address of
0xXXXXfffA which is wrong. (0xXXXXffff - 4) - 1...

Another question is:
Can someone test it with more than one bank, please? :-)

Regards
Alex
