Smartmedia cards _ARE_ dumb NAND flash chips in a thin plastic cover with gold contacts. The access to those cards is supported in the mtd subsystem since ages. Why are you trying to reinvent the wheel ? The only missing piece is the FTL layer, but there was a halfways working version in the old mtd CVS which should be still available. > management of flash memory.

It covers all the low level access to the NAND Flash and has a flexible interface to adapt to hardware. We really do not need a second incarnation of NAND flash software in the kernel.
