Kexec on P1020 - "Can't add kernel to addr 0x00000000"

[john hagen]

Hello,

I'm trying to make use of kexec on a couple of boards, a P1020rdb and
a custom P1011 board. My first attempts seem to report this "Can't add
kernel to addr 0x00000000". What is kexec trying to tell me? Looking
for a pointer here, thanks.
