Hello,

Our PASEMI Nemo board [1] doesn't boot with the PowerPC updates 6.4-1 
[2].

The kernel hangs right after the booting Linux via __start() @
0x0000000000000000 ...

I was able to revert the PowerPC updates 6.4-1 [2] with the following
command: git revert 70cc1b5307e8ee3076fdf2ecbeb89eb973aa0ff7 -m 1

After a re-compiling, the kernel boots without any problems without the
PowerPC updates 6.4-1 [2].

Could you please explain me, what you have done in the boot area?

There's a few possibilities, but nothing obvious.

To begin with can you please test the following commits?

cheers

git revert e4ab08be5b4902e5b350b0e1e1a3c25eb21d76d4

After a recompiling it boots without any problems.

e4ab08be5b49 -- powerpc/isa-bridge: Remove open coded "ranges" parsing 
is the bad commit.

Thanks
