[meta-freescale] [meta-fsl-arm][PATCH] linux-fslc-mx6-rt: Add new recipe
Dominic Sacré
dominic.sacre at gmx.de
Thu Oct 29 05:20:07 PDT 2015
This recipe is based on the now-deleted linux-imx-rt recipe, using the
same set of patches.
The linux-fslc-mx6 kernel is currently at upstream version 3.14.54, for
which no realtime patch has been released, but patch 3.14.51-rt52
applies cleanly.
