Subject: [PATCH v2 0/5] Enable PSP security attributes on more SoCs

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
