/**
- * Reset the @c examined flag for the given target.
- * Pure paranoia -- targets are zeroed on allocation.
+ * Streams data to a circular buffer on target intended for consumption by code
+ * running asynchronously on target.
+ *
+ * This is intended for applications where target-specific native code runs
+ * on the target, receives data from the circular buffer, does something with
+ * it (most likely writing it to a flash memory), and advances the circular
+ * buffer pointer.
+ *
+ * This assumes that the helper algorithm has already been loaded to the target,
+ * but has not been started yet. Given memory and register parameters are passed
+ * to the algorithm.
+ *
+ * The buffer is defined by (buffer_start, buffer_size) arguments and has the
+ * following format:
+ *
+ * [buffer_start + 0, buffer_start + 4):
+ * Write Pointer address (aka head). Written and updated by this
+ * routine when new data is written to the circular buffer.
+ * [buffer_start + 4, buffer_start + 8):
+ * Read Pointer address (aka tail). Updated by code running on the
+ * target after it consumes data.
+ * [buffer_start + 8, buffer_start + buffer_size):
+ * Circular buffer contents.
+ *
+ * See contrib/loaders/flash/stm32f1x.S for an example.
+ *
+ * @param target used to run the algorithm
+ * @param buffer address on the host where data to be sent is located
+ * @param count number of blocks to send
+ * @param block_size size in bytes of each block
+ * @param num_mem_params count of memory-based params to pass to algorithm
+ * @param mem_params memory-based params to pass to algorithm
+ * @param num_reg_params count of register-based params to pass to algorithm
+ * @param reg_params memory-based params to pass to algorithm
+ * @param buffer_start address on the target of the circular buffer structure
+ * @param buffer_size size of the circular buffer structure
+ * @param entry_point address on the target to execute to start the algorithm
+ * @param exit_point address at which to set a breakpoint to catch the
+ * end of the algorithm; can be 0 if target triggers a breakpoint itself

+/**
+* @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"
