It is supposed to be used for small on-chip SRAM
As stated in another thread [1], NAK to this patch.
Currently there are no users of this interface that we wish to enable for arm64, and this is liable to be abused to add platform-specific stuff that we expect to live in PSCI or other secure FW.
Until we have a user that does not fall into that bucket, I see no reason to enable this for arm64.
Thanks, Mark.
