Hi,
Yes I discovered the same issue today on MPC8321E, I plan to look at it
more closely tomorrow morning (Paris Time).
I think we are missing commit 8183d99f4a22c2abbc543847a588df3666ef0c0c ,
I didn't realise it when we applied the serie to 4.14,
patch_instruction() is called too early without that patch.
If you have opportunity to test now, you are welcome, otherwise I'll
test it tomorrow.

Hello, I got into troubles when I upgraded to Linux kernel 4.14.76 on
boards with MPC8321.
The symptom that I see is that the boot process gets cyclic, and no
printouts are seen from the Linux kernel. It seems like it resets.
When I revert the following commits it works again.
af1a8101794dfea897290e057f61086dabfe6c91, powerpc/lib: fix book3s/32
boot failure due to code patching
609fbeddb24c4035d24fc32d82dc08b30ae3dfc0, powerpc: Avoid code patching
freed init sections
Any ideas of how to continue?
