This new memtest can test the whole unused memory. The new memtest
command try to request the whole unused sdram regions on all banks and
run the mem_test routine from common/memtest.c on it.
The memtest command has only two parameters;
-i Amount of iterations, default 1, iteration of 0 is endless.
-b Set this to skip integrity check.(Do only a fast test for bus lines)
If MMU support is enable, memtest try to run memtest twice. The first with
cache enabled, the second with cache disabled.

The FSF address has changed in the past. Instead of updating it
each time the address changes, just drop it completely treewide.

No need to check for maximum argument counts. The commands are
safe to be called with more arguments, so lets safe some bytes.

The alternative memory test implementation needs a scratch
memory location to remove the last data from the data bus.
Instead of using a NULL pointer for this, default to the
memory start address.
No sane program should consider a NULL pointer as a safe default.

For practical reasons I changed all string literals assumed to be constant
to reside in .rodata subsection at end of .text section.
