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

[mar.krzeminski]

Hi,

It seem that I have found the root cause of the problem.
This board in qemu is set in this way, that device width is set to 2 and 
interface to 4.
That is why CFI driver in u-boot calculates wrongly sector size ( 
because size ratio variable was wrong ),
so in the end every odd sector (counting from 0 ) was not available.
I've changed vexpress board code in qemu and for now it is working.
I do not have real vexpress board to check if the root cause is u-boot 
or qemu,
but i think CFI driver i popular so propapbly there is something wrong 
in qemu site.

Regards,
Marcin
