-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.
