From 91e6f26f96c0ce4088f2c1d5110bd82591e15678 Mon Sep 17 00:00:00 2001 From: Chandni Cherukuri Date: Fri, 10 Aug 2018 11:17:58 +0530 Subject: [PATCH 1/4] plat/arm/sgi: reorganize platform macros In preparation of adding support for upcoming SGI platforms, macros common to all the SGI platforms are moved into sgi_base_platform_def.h file. Macros that are specific to sgi575 platform remain in the platform_def.h file. In addition to this, the platform_def.h file is moved to sgi575 board directory. Also the ENT_CPU_SOURCES has been renamed to SGI_CPU_SOURCES and moved from sgi-common.mk to board specific makefile platform.mk Change-Id: Iccdd9f070f4feea232b9fbf4fdcc0ef2e8eccbf2 Signed-off-by: Chandni Cherukuri --- plat/arm/board/sgi575/include/platform_def.h | 18 ++++++++++++++++++ plat/arm/board/sgi575/platform.mk | 11 ++++++++++- ...{platform_def.h => sgi_base_platform_def.h} | 13 +++---------- plat/arm/css/sgi/sgi-common.mk | 6 +----- 4 files changed, 32 insertions(+), 16 deletions(-) create mode 100644 plat/arm/board/sgi575/include/platform_def.h rename plat/arm/css/sgi/include/{platform_def.h => sgi_base_platform_def.h} (96%) diff --git a/plat/arm/board/sgi575/include/platform_def.h b/plat/arm/board/sgi575/include/platform_def.h new file mode 100644 index 000000000..1870fc78a --- /dev/null +++ b/plat/arm/board/sgi575/include/platform_def.h @@ -0,0 +1,18 @@ +/* + * Copyright (c) 2018, ARM Limited and Contributors.
