[PATCH] lite5200b: flash definition in dts

[Domen Puncer]

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":
[   11.208023] 0x00000000-0x01f00000 : "data"
[   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.
