md command
==========
Synopis
-------
::
md <address>[<data_size>] [<length>]
Description
-----------
The md command is used to dump the contents of memory. It uses a standard
format that includes the address, hex data and ASCII display. It supports
various data sizes and uses the endianness of the target.
The specified data_size and length become the defaults for future memory
commands commands.
address
start address to display
data_size
size of each value to display (defaults to .l):
========= ===================
data_size Output size
========= ===================
.b byte
.w word (16 bits)
.l long (32 bits)
.q quadword (64 bits)
========= ===================
length
number of values to dump. Defaults to 40 (0d64). Note that this is not
the same as the number of bytes, unless .b is used.
Example

The empty commands cause a 'repeat', so that md shows the next available data
in the same format as before.
Return value
------------
The return value $? is always 0 (true).
