8 years ago How is this a skiboot issue and not a BMC issue?

Problem statement: Install a habanero system with OpenPower Firmware, and do a golden side pnor boot. After further reboots system still booting always from golden side pnor firmware, and it is not booting from primary side pnor firmware.
How to Reproduce: 1.Install a Habanero system with latest OpenPower Firmware.
ipmitool sensor list | grep -i "boot count" Boot Count | 0x0 | discrete | 0x0280| na | na | na | na | na | na
initially boot count =0x02
Do a Power ON followed by immediate power off(To make sure boot fail early) check for boot count sensor value, it should be decremented by 1 ipmitool sensor list | grep -i "boot count" Boot Count | 0x0 | discrete | 0x0180| na | na | na | na | na | na
Do a Power ON followed by immediate power off for 2nd time(To make sure boot fail early) check for boot count sensor value, it should be decremented by 1 ipmitool sensor list | grep -i "boot count" Boot Count | 0x0 | discrete | 0x0080| na | na | na | na | na | na
Do a Power ON Operation to boot the system from golden side PNOR(Because boot count =0x00)

cd /sys/firmware/devicetree/base/xscom@3fc0000000000/isa@b0020/pnor@fc000000 lsprop *-tocs active-image-tocs 02000000 03ff8000 alternate-image-tocs 00000000 01ff8000 golden-image-tocs 02000000 03ff8000 Here we can observe at this stage system booted from golden side
Reboot the sytem again. reboot [ OK ] Started Show Plymouth Reboot Screen. [ OK ] Stopped Virtualization daemon. Stopping D-Bus System Message Bus... After completion of reboot check again system boot side still it is in golden side of pnor. cd /sys/firmware/devicetree/base/xscom@3fc0000000000/isa@b0020/pnor@fc000000 lsprop *-tocs active-image-tocs 02000000 03ff8000 alternate-image-tocs 00000000 01ff8000 golden-image-tocs 02000000 03ff8000

Further subsequent reboots also system is not booting from primary side of pnor, and it is always booting from golden side of pnor.
How to switch from golden side pnor to primary side pnor manually:
On BMC Busy box execute below command. /etc/init.d/boot_into_primary
Do a ipmi hard power reset to boot the system into primary. ipmitool power reset.
