Subject: [PATCH] Revert "mmc: disable UHS modes if Vcc cannot be switched on and off"
Got time to take a look?
Thanks, Peng.
This reverts commit 04a2ea248f58b3b6216d0cd0a6b8698df8b14355.
That commit is causing reboot loops on Nokia N900 and basically make U-Boot on Nokia N900 unusable. Revert it for now until problem is solved.
After reverting that commit U-Boot on Nokia N900 is working again.
