Subject: [PATCH] mmc: core: Fix bit width test failing on old eMMC cards
PARTITION_SUPPORT needs to be set before doing the compare on version
number so the bit width test does not get invalid data. Before this
patch, a Sandisk iNAND eMMC card would detect 1-bit width althoug
Elad,

I've been working on a bringup of an new board in Harmonic Inc.
This board uses Sandisk iNand eMMC flash.
I've noticed that the mmc driver keeps detecting 1 bit width although HW
supports 4 bit, looked into it, and found th
