[U-Boot] [PATCH 1/2] igep00x0: disable environment

[Ladislav Michl]

ISEE's U-Boot and Linux are using 1bit ECC scheme, while we
switched to 8bit ECC to fullfill flash specification requirements.
However when trying to run U-Boot on board with 1bit ECC'd data
on flash, UBI code takes several minutes to pass scan as reading
of every block ends with ecc error (which is also printed on
console).
So, until proper solution is developed, disable environment
alltogether.

[U-Boot] [PATCH 2/2] igep00x0: fixup FDT according to detected flash type

[Ladislav Michl]

Leave only detected flash type enabled in FTD as otherwise GPMC CS is
claimed (and never freed) by Linux, causing 'concurent' flash type
not to be probed.

Applied to u-boot/master, thanks!
