It's not so easy as may appear... using ioremap() & friends is not enought since flash memories may have different interfaces to the CPU. So the best way, IMHO, is accessing to flash memory by using the MTD interface... however I need also a gunzip() procedure and a way to decode BMP images in a compatibility manner for the current Linux's logo support.
