Hi all,

I'm using the latest kernel and I need the kexec support for 85xx
processor. When I use the menuconfig with ARCH=ppc and the 85xx and
e500 support, I have the kexec support, but when I use ARCH=powerpc I
haven't it, but I'm selecting the same processor!! Is it a bug in
kconfig? Somebody can help me?

Thanks in advance.

ARCH=ppc and ARCH=powerpc are not the same:
/usr/src/linux/arch/ppc is the old implementation,
/usr/src/linux/arch/powerpc is the new 32&64-bit merged implementation.

config KEXEC
bool "kexec system call (EXPERIMENTAL)"
depends on (PPC_PRPMC2800 || PPC_MULTIPLATFORM) && EXPERIMENTAL
You need to select PPC_MULTIPLATFORM.
(If you were using menuconfig, selecting "<Help>" would show you this.)

Your answer lies in /usr/src/linux/arch/powerpc/Kconfig:> config KEXEC

I know that ppc and powerpc are not the same, but first of all I can't
select PPC_MULTIPLATFORM because 85xx processors are not included
(this options is good only for 82xx,86xx, and so on) and second
Kconfig is different for the same processor with the same features in
ppc and powerpc. If there is the kexec support for 85xx in ppc,
why is there not in powerpc for the same processor? I hope now is more
clear.
