Description Andrea Adami 2017-11-02 22:53:25 UTC 
The OE toolchain using gcc7.1 and 7.2 produces unbootable kernels for armv5e.
I tested the gcc patch [2] and it fixes the issue on corgi/pxa255.

IMHO this fix needs to be merged and then backported to rocko.
Maybe with next gcc 7.3 ?

Cheers
Andrea
