Basic memory commands (mm. mw) work in any memory region that the
hardware supports.
You will have to be mindful of certain memory and interface devices
using only 16-bit or 8-bit access in a 32-bit architecture. Otherwise,
such attempts to use 32-bit read/write will result in the most
significant short-word or byte NOT to carry valid data value.
TFTP does work writing directly into unprotected FLASH region if the
CFG_DIRECT_FLASH_TFTP is defined in your include/configs/<board>.h file.
