[meta-freescale] [CRITICAL] Boards failing to build with GCC 5.2 - Kernel patches are needed

[Otavio Salvador]

Hello folks,

I have been working at stabilizing the core BSP boards (Freescale
reference boards) for Yocto Project 2.0 release - jethro. As most of
you are aware one of the changes for this release is the GCC version
update.

The vendors needing to check the boards are:

Boundary Devices
CompuLab
Congatec
Crystalfontz
DENX
Device Solutions
Phytec
SolidRun
Wandboard.org

These vendors are responsible for one, or more, of the following boards:

imx6qsabrelite (Boundary Devices i.MX6Q SABRE Lite)
nitrogen6sx (Boundary Devices Nitrogen6SX)
nitrogen6x (Boundary Devices Nitrogen6X)
nitrogen6x-lite (Boundary Devices Nitrogen6X Lite)
cm-fx6 (CompuLab CM-FX6)
cgtqmx6 (Congatec Qmx6)
cfa10036 (Crystalfontz CFA-10036)
cfa10037 (Crystalfontz CFA-10037)
cfa10049 (Crystalfontz CFA-10049)
cfa10055 (Crystalfontz CFA-10055)
cfa10056 (Crystalfontz CFA-10056)
cfa10057 (Crystalfontz CFA-10057)
cfa10058 (Crystalfontz CFA-10058)
quartz (Device Solutions Quartz Vybrid Development Kit)
ventana (i.MX6Q/DL Ventana Platform)
pcl052 (Phytec Cosmic Vybrid Development Kit)
pcm052 (Phytec phyCORE Vybrid Development Kit)
cubox-i (SolidRun CuBox-i and HummingBoard)
wandboard (Wandboard i.MX6 Wandboard Quad/Dual/Solo)
m28evk (DENX M28 SoM Evaluation Kit)
m53evk (DENX M53 SoM Evaluation Kit)

For i.MX6 based boards, the linux-fslc-mx6 kernel has the patches
applied as it is updated with the Linux 3.14 stable releases.
Following patches are worth checking:

 - allow the Vivante GPU kernel module to work:
   https://github.com/Freescale/linux-fslc/commit/22f692548037e39809c32759b5600ee066ef59e9.patch

 - GCC 5.2 fixes :
   https://github.com/Freescale/linux-fslc/commit/aeea3592a13bf12861943e44fc48f1f270941f8d.patch
   https://github.com/Freescale/linux-fslc/commit/76ae03828756bac2c1fa2c7eff7485e5f815dbdb.patch

For other SoCs the linux-fslc 4.1 branch seems to be a good option to
avoid the local recipe and this maintenance burden.

WARNING: I will REMOVE boards which are kept broken so please respond
to this email with a plan for fixing it.

Best Regards,
