p54: improve eeprom parser
Like other vendors, p54* devices have a checksum for
the EEPROM descriptor data. This patch enhances the
parser code to generate and verify the data fields,
before initializing the radio-chip on the card.
Note:
If you have to bootstrap an alternative EEPROM image
for your device and you don't know how to generate a
valid crc ccitt checksum, you should take a look at:
http://git.kernel.org/?p=linux/kernel/git/chr/p54tools.git
The "checksum" utility loads a binary p54 EEPROM blob
(use the -f switch, to skip the check) and applies
the correct crc automatically.
