From 8d13298b8008ff62e107deb2a293ea267943a977 Mon Sep 17 00:00:00 2001 From: Ard Biesheuvel Date: Tue, 28 Jul 2015 20:44:44 +0000 Subject: ArmPkg: split off ArmGicArchLib from ArmGicLib The current implementation of ArmGicGetSupportedArchRevision () that is used by all ARM platforms is entirely stateless (in order to support being executed from flash) so it needs to interrogate the hardware for the supported GIC revision upon each invocation. However, this statelessness is only needed for SEC type modules; in all other cases, we could easily determine the GIC revision once, and store the result in a global variable. In preparation of having separate early and normal versions, this patch introduces the ArmGicArchLib library class and default implementation, and moves the existing ArmGicGetSupportedArchRevision () into it.
