Problem booting Kernel 4.8-rc1 on Sam460ex ( Canyonlands) machine .
This is what I get with the bisect.
Hi Julian
I have no Sam460ex machine, could you show the good and bad kernel
bootlog?
I have no experience about PowerPC, the status shows below,
version boot
v4.7 ok
v4.8-rc1 fail
v4.7 + this patch fail(right?)
Does PowerPC support earlyprintk/earlycon? Please set it, and let's show
somethings from earlyprintk.
Not getting any output with earlyprintk so not sure if it works or if my
settings are incorrect .
This should work: earlycon=uart8250,mmio,ef600300,115200n8
Adding "initcall_debug debug" would also be useful here.
I tried to revert the commit but the result is the same so I suspect that
this one may not really be the problem .
Looks like the real problem may be something affecting the the device tree
loading .
That's strange. If it is this commit, the init order changes as it
changed from device to arch initcall. I haven't seen any other
platforms having problems.

The following patch fixes my issue.

Thank you
