The following changes are done in this patch:
1. Get the CSE partition info containing version of CSE RW using
GET_BOOT_PARTITION_INFO HECI command
2. Get the me_rw.version from the currently selected RW slot.
3. If the versions from the above 2 locations don't match start the update
- If CSE's current boot partition is not RO, then
* Set the CSE's next boot partition to RO using SET_BOOT_PARTITION
HECI command.
* Send global reset command to reset the system.
- Enable HMRFPO (Host ME Region Flash Protection Override) operation
mode using HMRFPO_ENABLE HECI command
- Erase and Copy the CBFS CSE RW to CSE RW partition
- Set the CSE's next boot partition to RW using
SET_BOOT_PARTITION HECI command
- Trigger global reset
- The system should boot with the updated CSE RW partition.
TEST=Verified basic update flows on hatch and helios.
