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