From e314d564db4d52a9e904f6049dad7fc5dece5cb4 Mon Sep 17 00:00:00 2001 From: oliviermartin Date: Wed, 2 May 2012 20:13:32 +0000 Subject: ArmPlatformPkg: Introduced 'ArmPlatformSecLib' The function only used in Secure Firmware used to be mixed with the Non-Secure/Normal functions in ArmPlatformLib. When the Secure Firmware was not required for some platforms (eg: BeagleBoard), these functions were empty functions. This new interface has been created to clean the ArmPlatformLib interface between the SEC and PEI phases.
