powerpc/powernv: Code update interface
Code update interface for powernv platform. This provides
sysfs interface to pass new image, validate, update and
commit images.
This patch includes:
- Below OPAL APIs for code update
- opal_validate_flash()
- opal_manage_flash()
- opal_update_flash()
- Create below sysfs files under /sys/firmware/opal
- image : Interface to pass new FW image
- validate_flash : Validate candidate image
- manage_flash : Commit/Reject operations
- update_flash : Flash new candidate image
Updating Image:
"update_flash" is an interface to indicate flash new FW.
It just passes image SG list to FW. Actual flashing is done
during system reboot time.
Note:
- SG entry format:
I have kept version number to keep this list similar to what
PAPR is defined.
