The ioremap fails before it can get this far because there is no start
address or size defined for the default device. I've patched in a
generic map as follows and its then fine.
struct map_info physmap_map = {
.name = "phys_mapped_flash",
.size = CONFIG_MTD_PHYSMAP_LEN,
.buswidth = CONFIG_MTD_PHYSMAP_BUSWIDTH,
.phys = CONFIG_MTD_PHYSMAP_START,
};
I may have missed something here - perhaps something is supposed to set
these values by probing but if thats the case I've missed it I'm afraid!!
