I am facing an issue where kernel built with gcc 5.2.0 hangs the board after the device tree is loaded.

I used current poky and meta-fsl-ppc layers to compile the image.


Boot Log:

WARNING: adjusting available memory to 30000000

## Booting kernel from Legacy Image at 01000000 ...

   Image Name:   Linux-3.12.37-rt51

   Image Type:   PowerPC Linux Kernel Image (gzip compressed)

   Loading Device Tree to 03fde000, end 03fffc40 ... OK



Note that this is observed only with the new v5.2.0 gcc and kernel built with gcc v4.9.1 boots just fine.


It appears that a similar issue was reported and fixed for e500v2 targets a year ago.
