BMC shall assert SPECIAL_BOOT GPIO to the CPU to trigger Host Secure
Provision. Then BMC shall reset the system, or turn on the system if
it is being OFF.
After the host enters Provisioning Boot Mode successfully (or having
failure), BMC shall deassert the SPECIAL_BOOT GPIO to LOW.
Tested:
1. Flash HostFW with PASS case.
- $ ampere_flash_bios.sh spinor.img 1 1
- Host boot with logs:
[00:00:00.248,000] <inf> scu_stat: is_special_boot() = 1
[00:00:00.383,000] <inf> SECpro_cert_ext: Assert FW_BOOT_OK
[00:00:00.383,000] <inf> SECpro_cert_ext: Deassert FAULT_ALERT
[00:00:00.383,000] <inf> SECpro_cert_ext: SEC provision completed \
successfully
2. Flash HostFW with FAULT case.
- $ ampere_flash_bios.sh spinor_fault.img 1 1
- Host boot with logs:
[00:00:00.253,000] <inf> scu_stat: is_special_boot() = 1
[00:00:00.388,000] <err> SECpro_cert_ext: Invalid version cert 0.0
[00:00:00.388,000] <inf> SECpro_cert_ext: Assert FW_BOOT_OK
[00:00:00.388,000] <err> SECpro_cert_ext: SEC provision failed
[00:00:00.388,000] <err> SECpro_cert_ext: Sending error on \
FAULT_ALERT
3. Turn off the Host, flash HostFW with PASS case. After flash done,
Host boot with logs is the same with step #1.
