Subject: [PATCH v3 00/10] firmware: arm_ffa: Refactoring and initial/minor v1.1 update

Hi All,

This series is just some refactoring in preparation to add FF-A v1.1
support. It doesn't have any memory layout or notification changes
supported in v1.1 yet.

Regards,
Sudeep

v2[2]->v3:
	- Fixed the logic to set 32bit mode which was wrong.
	- Ensured that we advance each partition info size by returned
	  size even if the size is greater than the partition_info structure,
	  we will still just copy the right size.

v1[1]->v2[2]:
	- Merged dropping of ffa_ops in optee_ffa structure and using
	  ffa_dev->ops into single patch
	- Added separate patch(didn't fit any patch strictly to fit in)
	  to rename ffa_dev_ops as ffa_ops as suggested by Sumit
	- Fixed some minor comments, handling size > structure size in
	  partition_info_get and added extra parameter to ffa_features
	  to get both possible output/interface properties.
