When I tried this patchset, it fails to boot my SabreLite.  The
important bits seem to be the MMC device numbering.  From the boot log:
     <snip>
   mmc3: new high speed SDHC card at address aaaa
   mmcblk3: mmc3:aaaa SU04G 3.69 GiB
    mmcblk3: p1 p2
     <snip>
   ALSA device list:
     #0: imx6q-sabrelite-sgtl5000
   Waiting for root device /dev/mmcblk0p2...

I see no difference when setting 'sdphys' or not.  Perhaps I missed some
other patch (like to the boot scripts)?

I'd really like to get my board back up with the latest kernel.
