Hi all,
Here are some patches to make kexec work for SMP omaps. To test
these you need to use the latest kexec-tools.git kexec with
Russell's recent patches in "[PATCH 0/2] Simple fix to the ARM
kexec tools implementation" thread fixed for 6x. Or else you
need to use appended DTB.
I've tested these so far on 4430 duovero, omap5-uevm, and
beagle-x15.
More testing done with above configuration + kexec_tools change below:
initrd_base = kernel_base + _ALIGN(len * 7, getpagesize());
kexec works fine on:
am437x-gp-evm, am437x-sk-evm
am335x-bone
dra72-evm
dra7-evm
omap5-uevm
Tested-by: Keerthy <j-keerthy@xxxxxx>
