[U-Boot] U-boot and UBI problem with vexpress board.

[mar.krzeminski]

Hello Heiko,

I tried all people I know and unfortunately no one has this board.
If someone has this board here, it is very easy to check.
1. fli command returns number of sectors. Should be 256 sectors, in 
wrong case is 128.
Also sector addresses differs by 0x80000 in wrong case, but should be 
0x40000.
2. saveenv command fails if this bug is present.

Regards,
Marcin
