Try the rpxlite map driver which I've added to the CVS tree. If it doesn't
work, let me have a patch for it.
There's also a 'physmap' driver for normal physical mappings of flash
chips, which require ioremap() to get a virtual mapping - unlike nora.c
which has a virtual mapping set up for it by the kernel's VM init code.
