[U-Boot] [PATCH 3/3] ubi: Add proof-of-concept CFI flash support

[Piotr Ziecik <kosmo@semihalf.com>]

With this patch UBI can be used on CFI flash chips.

Signed-off-by: Piotr Ziecik <kosmo@semihalf.com>
---
For example to create UBI volume on empty flash partition
(partition 0 on NOR device 0) use following commands:

=> setenv mtdids nor0=nor
=> mtdparts add nor0 8m at 32m nor-part
=> saveenv
=> ubi part nor nor0,0
=> ubi create ubi-vol
=> ubi info layout
