On some older SoCs the PSP doesn't export security attributes in the
capabilities register. On these SoCs it is however possible to get
the information by a platform access command.
Restructure the driver to move all security attribute handling to
a central location and then add support for calling the platform
access command on those processors.
v1->v2:
* Add tags (except patch 2)
* Fix kernel robot reported issue
* Move a check from patch 4 to patch 5
Mario Limonciello (5):
crypto: ccp: Represent capabilities register as a union
crypto: ccp: Move security attributes to their own file
crypto: ccp: align psp_platform_access_msg
crypto: ccp: Add support for getting security attributes on some older
systems
crypto: ccp: Move message about TSME being enabled later in init
