[U-Boot] uboot env in mmc partition

[Naitik Amin]

More info..

Below is what I see on bootup.

My env is at 0x100000 from base of sd card. It seems something happened on 
the hash insert.

Hi Peter,
i don't think that your patch has influence on this issue, due to no 
partition switching is done anymore.

Further i would like to check your patch series, i am not sure if there is 

everything ok.
I will do so tommorow - i am right in thinking that you are using MMC not 
eMMC ?

best regards,
Hannes
