This patch adds support for the 3.10.31_1.1.0_beta kernelfor Boundary
Devices BD-SL-i.MX6 (built to SABRE Lite), Nitrogen6X, Nitrogen6_Max
and and Nitrogen6_Lite boards.
To try it out, set PREFERRED_VERSION_linux-boundary = "3.10.31" in your
local.conf file.
Minimal testing has been performed at this point, so don't expect it
to be production-ready.
Note that the 3.10.31 kernel contains an update to provide fixed
numbering for /dev/mmcblk devices instead of numbering them by
order of initialization.
Support has been added into the boot script, but requires setting
a variable in U-Boot:
U-Boot > setenv sdphys 1
U-Boot > saveenv
U-Boot > boot
See this post for some additional commentary:

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)?
BTW, I'm building the scripts from
u-boot-script-boundary/v2014.07+gitAUTOINC+f870252376
and there seems to be nothing in there about sdphys
You need this patch to support the 'sdphys' thing in the boot script:

Thanks, I had missed that one. It's booting again.
Next problem - I have no video, neither with HDMI nor 7" LCD
Ideas?
Any progress with this (no video at all)? I've tried the
latest Boundary Devices kernel (b76cf1c04) whose comment
implies this should be fixed, but still no-go.
For completeness, here are some relevant messages at boot:
