Is this for current release or next ?

What's the size impact of this? What is the actual problem? From this description, I would think the message needs to be fixed instead of adding cache drivers?
We're already quite constrained in gen5. I'm not keen on adding drivers just because of an error message...

Can drop this patch first. Just found out only see this error when enable ECC scrubbing with Dcache in Gen5 in our downstream branch. But, mainline Uboot haven't support ECC in Gen5 yet. Will add this patch when enable ECC in Gen5 later.
Thanks.
