[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).
