If I try to "cp.b <ram> <dataflash>", u-boot selects normal flash
routines instead of dataflash. This is because it checks "if source
address is not dataflash" instead of target address.

If the length of the memory address range passed to the "mtest" command is
not of the form 2^x - 1, not all address lines are tested. This bug is
inherited from the original software at
http://www.netrino.com/Embedded-Systems/How-To/Memory-Test-Suite-C. Fix
this.

Current MII_DEBUG is confusing in two ways. One is useless define-then-
undef at the top of the file. The other is there is only one debug() in
this file, and that doesn't seem worthwhile to bother having MII_DEBUG.
While there are many useful printf()/puts() debug codes, but they are for
DEBUG, not for MII_DEBUG.

This patch tries to put them all together into MII_DEBUG and debug().
