Staging: wlan-ng: Convert firmware loading to load binary ihex format

Browse source

Convert prism2_usb firmware loading to load firmware in pre-compiled
binary 'ihex' format rather than ascii 'srec' format. This moves the
srec processing and sorting of records out of kernel space into a
pre-compiler. The driver now just works with the binary image, but
still does the 'pda plugging' of that image at runtime, as required
by the prism hardware.

Some Notes:

- The firmware is now expected to be in the same 'ihex' (.fw) format
  used by other drivers.

- The now driver assumes the data records are already sorted into ascending
  address order.

- Plug and crc records are still recognised by special address locations
  as in original srec processing.

- The srec S7 start address record is assumed to have been converted
  into a data record with another special address location (0xff400000),
  with the original start address being stored as a 4 byte data word
  (little endian).
