[MTD] [NAND] Driver for Olympus MAUSB-10 and Fujifilm DPC-R1 card readers
Unlike most stuff on the market the chip inside these two allows raw
flash access and doesn't implement and FTL, leaving that functionality
to the device driver.
Raw flash access in a cheap USB cardreader! An MTD test device one can
attach to a PC! What a deal!
The command set of the chip is not documented, so information was
obtained from the existing mass-storage driver
(drivers/usb/storage/alauda.c), its documentation
(http://alauda.sourceforge.net/wikka.php?wakka=BulkCommandReference),
additional reverse engineering and comparison with a vendor driver for a
related chip
(http://www.ratocsystems.com/english/download/driver/linux/sma03u.html).
