6bed7ce569 dfu: Implementation of target reset after communication with dfu-util's -R switch
This patch extends dfu code to support transmission with -R switch
specified at dfu-util.

When -R is specified, the extra USB_REQ_DFU_DETACH request is sent after
successful data transmission. Then dfu resources are released and reset
command is issued.

e7e75c70c5 dfu: make data buffer size configurable
Dfu transfer uses a buffer before writing data to the
raw storage device. Make the size (in bytes) of this buffer
configurable through environment variable "dfu_bufsiz".
Defaut value is configurable through CONFIG_SYS_DFU_DATA_BUF_SIZE

ea2453d56b dfu: Support larger than memory transfers.
Previously we didn't support upload/download larger than available
memory.  This is pretty bad when you have to update your root filesystem
for example.

This patch removes that limitation (and the crashes when you transfered
any file larger than 4MB) by making raw image writes be done in chunks
and making file maximum size be configurable.

The sequence number is a 16 bit counter; make sure we handle rollover
correctly. This fixes the wrong transfers for large (> 256MB) images.

Also utilize a variable to handle initialization, so that we don't rely
on just the counter sent by the host.

f22b11c10d dfu: DFU backend implementation
New, separate driver at ./drivers/dfu has been added. It allows platform
and storage independent operation of DFU.
It has been extended to use new MMC level of command abstraction.
