Dear all,
I am trying current U-Boot master on solidrun microsom i.MX6 and I get a CACHE
error when accessing SD device:

U-Boot SPL 2017.01-rc1-00066-ge5209e3-dirty (Dec 14 2016 - 10:55:06)

U-Boot version is 53e8ca22538c2cec691fe74098684a359302688c with 54e4fcfa3c749a789192e83740a53234182f4ca3 reverted.

I have tried building also with gcc 4.8 without any improvement.
I have not verified if SD is working correctly.
I am using mx6cuboxi_defconfig without any modification.

U-Boot v2016.03 is not showing the problem.

For the sake of completeness the board is a solidrun SOM i4Pro Rev-1.5 on a
HummingBoard2 Edge Rev-1.2

Thanks,
Francesco
