[Qemu-ppc] Booting AIX on qemu-system-ppc, kernel not started successfully

[Liang Guo]

Hi, 

I use the latest IBM standalone Diagnostics CD to test AIX on qemu/ppc, 
IBM standalone diagnostics CD can be downloaded from:

  http://www-304.ibm.com/webapp/set2/sas/f/diags/download/home.html

I use the following command line to start qemu:

  qemu-system-ppc64 -cpu POWER7 -machine pseries -m 1024 -serial stdio \
  -cdrom /u01/vm/CDlatest.iso -monitor \
  unix:/tmp/ppc64-aix,server,nowait -nographic

when "0 >" promprt appears, I input:
  setenv load-base 16384
  boot cdrom:\ppc\chrp\bootfile.exe  -s verbose 

This is the detailed output:
$ ./qemu.sh 
sPAPR memory map:
RTAS                 : 0x3fff0000..3fff0013
FDT                  : 0x3ffe0000..3ffeffff
Firmware load        : 0x00000000..000d44d0

It looks like aixmon_chrp passed the control to aix kernel, but the aix
kernel cannot work as ecpected. 

AIX 5.3, 6.1 and 7 failed to boot and give the exactly same error
message. 

Any advice ?

Thanks and Regards,
