powerpc/powernv: Pass buffer size to OPAL validate flash call We pass actual buffer size to opal_validate_flash() OPAL API call and in return it contains output buffer size. Commit cc146d1d (Fix little endian issues) missed to set the size param before making OPAL call. So firmware image validation fails. This patch sets size variable before making OPAL call.

powerpc/powernv: Return secondary CPUs to firmware before FW update Firmware update on PowerNV platform takes several minutes. During this time one CPU is stuck in FW and the kernel complains about "soft lockups". This patch returns all secondary CPUs to firmware before starting firmware update process.

powerpc/powernv: Create OPAL sglist helper functions and fix endian issues We have two copies of code that creates an OPAL sg list. Consolidate these into a common set of helpers and fix the endian issues. The flash interface embedded a version number in the num_entries field, whereas the dump interface did did not. Since versioning wasn't added to the flash interface and it is impossible to add this in a backwards compatible way, just remove it.

powerpc/powernv: Increase candidate fw image size At present we assume candidate image is <= 256MB. But in P8, candidate image size can go up to 750MB. Hence increasing candidate image max size to 1GB. Signed-off-by: Vasant Hegde <hegdevasant@linux.vnet.ibm.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

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.
