The max payload size is negotiated through the configure and configure
response messages. Update the max payload size based on the
configuration response value, if present.

During program it's recommended to reduce the num_sectors to only cover
the sectors containing data to be written and not write zero-block in
the rest. This reduce the time spent sending unnecessary blocks of
zeros.

Reduce the number of write operations by batching up sectors in a
max_payload_size sized buffer and write them in one chunk. Using the
qcserial driver will still chop up the USB traffic in 4kB chunks, so no
measurable perfomance improvement is seen.

The MaxPayloadSizeToTargetInBytes parameter of the configure command is
supposed to set the maximum size of the transfer unit. This size is
however limited by the use of the in-kernel qcserial driver and the use
of sector-sized writes. Yet increasing it, drastically bumps the
transfer speed, so leave it high.

NB. The max payload size supported by the device is part of the
configure response, if the device supports a value less than the
requested size - which we just ignore today.

This bootable device is not always partition number 1. Search the
program entries for an entry that has the label xbl or sbl1 and use the
partition number to mark the boot partition bootable.

The DONE message contains a return code denoting if the firmware is done
(1) requesting files from the host, or if there are more requests to
come (0). Unfortunately on some platforms the ROM code sends 0
regardless, so we just have to assume that we're done.

This assumes that there is only ever one image to transfer.

GNU coding standards notably specifies:
 * install files with the $(DESTDIR) to the target system image
 * install files with the $(prefix), not $(PREFIX)
 * the default value of $(prefix) should be /usr/local

as per
