21The ELAN-104NC has up to 8 Mibyte of Intel StrataFlash (28F320/28F640) in x16
22mode. This drivers uses the CFI probe and Intel Extended Command Set drivers.
23
24The flash is accessed as follows:
25
26 32 kbyte memory window at 0xb0000-0xb7fff
27
28 16 bit I/O port (0x22) for some sort of paging.
29
30The single flash device is divided into 3 partition which appear as separate
31MTD devices.
32
33Linux thinks that the I/O port is used by the PIC and hence check_region() will
34always fail. So we don't do it. I just hope it doesn't break anything.
