/**
* @brief Reads an array of words/halfwords/bytes from target memory starting at specified address.
*
* Usage: mdw [phys] <address> [<count>] - for 32 bit reads
* mdh [phys] <address> [<count>] - for 16 bit reads
* mdb [phys] <address> [<count>] - for 8 bit reads
*
* Count defaults to 1.
*
* Calls target_read_memory or target_read_phys_memory depending on
* the presence of the "phys" argument
* Reads the target memory in blocks of max. 32 bytes, and returns an array of ints formatted
* to int representation in base16.
* Also outputs read data in a human readable form using command_print
*
* @param phys if present target_read_phys_memory will be used instead of target_read_memory
* @param address address where to start the read. May be specified in decimal or hex using the standard "0x" prefix
* @param count optional count parameter to read an array of values. If not specified, defaults to 1.
* @returns: JIM_ERR on error or JIM_OK on success and sets the result string to an array of ascii formatted numbers
* on success, with [<count>] number of elements.
*
* In case of little endian target:
* Example1: "mdw 0x00000000" returns "10123456"
* Exmaple2: "mdh 0x00000000 1" returns "3456"
* Example3: "mdb 0x00000000" returns "56"
* Example4: "mdh 0x00000000 2" returns "3456 1012"
* Example5: "mdb 0x00000000 3" returns "56 34 12"
