Unless I'm smoking crack, the CFI command set code _does_ support erases 
longer than one erase block. The three checks which could cause it to 
return EINVAL are:
	1. start address must be erase-block-aligned
	2. length needs to be a multiple of erase block size.
	3. start + length must not exceed the _total_ size of the device.


The DiskOnChip code is different, but that's been/being fixed - depending 
on whether the patch has hit the CVS tree yet or not.
