-@deffn {Command} {$target_name array2mem} arrayname width address count
-@deffnx {Command} {$target_name mem2array} arrayname width address count
-These provide an efficient script-oriented interface to memory.
-The @code{array2mem} primitive writes bytes, halfwords, words
-or double-words; while @code{mem2array} reads them.
-In both cases, the TCL side uses an array, and
-the target side uses raw memory.
-
-The efficiency comes from enabling the use of
-bulk JTAG data transfer operations.
-The script orientation comes from working with data
-values that are packaged for use by TCL scripts;
-@command{mdw} type primitives only print data they retrieve,
-and neither store nor return those values.
