I think it might make more sense to put the MMC ifdef after the onenand code so that it doesn't split the nand/onenand grouping. Otherwise it matches what I did.

This is a void function and shouldn't have a return value. I fixed this in my version.
gd->env_valid = 1;
I removed this in my version, probably an error to do that though :-)

I previously submitted a patch to fix this and Wolfgang sent an email saying that it had been applied.

I'll revise my patch to add the missing gd->env_valid = 1; and re-test.
