Title:
imx6: sata fixes
Status in “linux” package in Ubuntu:
Fix Committed
Status in “linux” source package in Saucy:
Fix Released
Bug description:
SRU Justification:
Impact:
/dev/sda doesn't show up on imx6 board and while support for the sata
controller was submitted upstream[1], we were missing a dts snippet that didn't
make the 3.11 window (but entered as part of 3.12, thus i cherry-picked plus
some mechanical
modification to make it apply).
Moreover, building this driver as a module triggers an error when
loading:

as it appears it's the same driver that tries to create the same
sysfile multiple times, failing:

Statically compiling support for AHCI_IMX works workaround this
problem (and all the other kernel supporting this board - indeed -
compile this driver statically BTW), so until a proper fix is found, i
propose to compile it in.
Fix:
apply the two patches below
Testcase:
compile a patched kernel and boot it
