fetching calibration data from flash

currently ath10k fetches calibration data from the board.bin file
via request_firmware(). Usually HW manufactures are using one
flash partition for the calibration data (see ath9k for example).
So we would end up reading the file from flash, and writing it into
a ramdisk so that ath10k can fetch it.
I would prefer to add support to ath10k to fetch that data directly from
flash. IMHO there are two options to do so:
a) Use platform data, like ath9k does.
b) add a module option to ath10k, and let ath10k fetch the files via mtd
Has the downside of requiring MTD (maybe add a config option to
but i like that more than the ath9k way of reading an arbitrary
memory region and
circumventing the MTD layer.
Any thoughts? I can prepare a patch if needed.
