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.

Ciao,
