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

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.
