Hi Andy,
I was going through the MMC code, trying to get Phison 8007 SD-to-NAND bridge working (don't ask please, this chip's sole existence defies any logic).
So, I found the following code and I was wondering if the following patch is not needed. Maybe my brain is just giving up though. Give it some thought please and let me know, thanks!
