508 * hand the infrastructure for running such helpers might use this

4353 * @brief Reads an array of words/halfwords/bytes from target memory starting at specified address.
4355 * Usage: mdw [phys] <address> [<count>] - for 32 bit reads
4356 * mdh [phys] <address> [<count>] - for 16 bit reads
4357 * mdb [phys] <address> [<count>] - for 8 bit reads
4359 * Count defaults to 1.
4361 * Calls target_read_memory or target_read_phys_memory depending on
4362 * the presence of the "phys" argument
4363 * Reads the target memory in blocks of max. 32 bytes, and returns an array of ints formatted
4364 * to int representation in base16.
4365 * Also outputs read data in a human readable form using command_print
4367 * @param phys if present target_read_phys_memory will be used instead of target_read_memory
4368 * @param address address where to start the read. May be specified in decimal or hex using the standard "0x" prefix
4369 * @param count optional count parameter to read an array of values. If not specified, defaults to 1.
4370 * @returns: JIM_ERR on error or JIM_OK on success and sets the result string to an array of ascii formatted numbers
4371 * on success, with [<count>] number of elements.
4373 * In case of little endian target:
4374 * Example1: "mdw 0x00000000" returns "10123456"
4375 * Exmaple2: "mdh 0x00000000 1" returns "3456"
4376 * Example3: "mdb 0x00000000" returns "56"
4377 * Example4: "mdh 0x00000000 2" returns "3456 1012"
4378 * Example5: "mdb 0x00000000 3" returns "56 34 12"
