From 8d0fe26cbf66739ba80f7d2fc6acb683cecbf68f Mon Sep 17 00:00:00 2001 From: oliviermartin Date: Tue, 1 Nov 2011 23:36:59 +0000 Subject: [PATCH] ArmPlatformPkg: Remove ArmPlatformBootRemapping() function from the ArmPlatformLib Memory map remapping is a platform specific feature only enabled by some platforms. Instead of keeping this function empty for most platforms, the function has been removed. This feature can easily fit in any other ArmPlatformLib function. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@12632 6f19259b-4bc3-4df7-8a09-765794883524 --- .../ArmRealViewEbLibRTSM/ArmRealViewEb.c | 19 ++--------- .../Library/ArmVExpressLibCTA9x4/CTA9x4.c | 34 ++++++------------- .../Library/ArmVExpressLibRTSM/RTSM.c | 19 ++--------- .../Include/Library/ArmPlatformLib.h | 12 ------- .../ArmPlatformLibNull/ArmPlatformLibNull.c | 15 -------- ArmPlatformPkg/Sec/Sec.c | 4 --- 6 files changed, 16 insertions(+), 87 deletions(-) diff --git a/ArmPlatformPkg/ArmRealViewEbPkg/Library/ArmRealViewEbLibRTSM/ArmRealViewEb.c b/ArmPlatformPkg/ArmRealViewEbPkg/Library/ArmRealViewEbLibRTSM/ArmRealViewEb.c index ba90e19119..cb92bf00a2 100644 --- a/ArmPlatformPkg/ArmRealViewEbPkg/Library/ArmRealViewEbLibRTSM/ArmRealViewEb.c +++ b/ArmPlatformPkg/ArmRealViewEbPkg/Library/ArmRealViewEbLibRTSM/ArmRealViewEb.c @@ -47,22 +47,6 @@ ARM_CORE_INFO mRealViewEbMpCoreInfoTable[] = { } };
