Add flash definition for flash on lite5200b, and while at it
fix "ranges" for soc node.
Kernel now writes:
[ 11.159134] fe000000.flash: Found 2 x8 devices at 0x0 in 16-bit bank
[ 11.165696] Amd/Fujitsu Extended Query Table at 0x0040
[ 11.171109] fe000000.flash: CFI does not contain boot bank location.
Assuming top.
[ 11.178911] number of CFI chips: 1
[ 11.182427] cfi_cmdset_0002: Disabling erase-suspend-program due to code
brokenness.
[ 11.190402] RedBoot partition parsing not available
[ 11.195449] physmap-flash fe000000.flash: Using OF partition information
[ 11.202359] Creating 2 MTD partitions on "fe000000.flash":

[ 11.213712] 0x01f00000-0x02000000 : "u-boot"
I have not managed to write anything to flash from Linux, ideas?
JEDEC probe does not succeed.
CFI does (cfi_ident struct is filled and "looks" OK),
but mfr and id are 0xffff.
