KEXEC on ARM cortex-a15

[Naresh Bhat]

Hi All,

I am trying to test KEXEC feature on Cortex-a15 architecture.

I am using Kernel.org v3.4 kernel, and a u-boot boot loader on
Daughterboard Site 1: V2P-CA15_A7 Cortex A15

My question is do I need to pass any ATAG related information from
u-boot to Kernel ?? If so what should I pass ??

Please,  help me to overcome from below error message.

Error Message:


I can see the below question on dmesg "No ATAGs ?"
