From 198a97a6abe7090109002baea0d2cb46070955aa Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Fri, 27 Feb 2015 02:26:51 +0900 Subject: [PATCH] ARM: UniPhier: split clkrst_init() into two functions Split the current clkrst_init() into two functions: - early_clkrst_init(): called from SPL Deassert the reset signals of the memory controller and some other basic cores. - clkrst_init(): called from main U-boot Deassert the reset signals that are necessary for the access to peripherals etc. Signed-off-by: Masahiro Yamada --- arch/arm/mach-uniphier/board_early_init_f.c | 5 ++++ arch/arm/mach-uniphier/ph1-ld4/Makefile | 4 +-- arch/arm/mach-uniphier/ph1-ld4/clkrst_init.c | 22 +++++++++++----- arch/arm/mach-uniphier/ph1-ld4/early_clkrst_init.c | 1 + arch/arm/mach-uniphier/ph1-pro4/Makefile | 4 +-- arch/arm/mach-uniphier/ph1-pro4/clkrst_init.c | 22 +++++++++++----- .../arm/mach-uniphier/ph1-pro4/early_clkrst_init.c | 26 +++++++++++++++++++ arch/arm/mach-uniphier/ph1-sld8/Makefile | 4 +-- arch/arm/mach-uniphier/ph1-sld8/clkrst_init.c | 30 +--------------------- .../arm/mach-uniphier/ph1-sld8/early_clkrst_init.c | 1 + arch/arm/mach-uniphier/spl.c | 4 +-- 11 files changed, 74 insertions(+), 49 deletions(-) create mode 100644 arch/arm/mach-uniphier/ph1-ld4/early_clkrst_init.c create mode 100644 arch/arm/mach-uniphier/ph1-pro4/early_clkrst_init.c create mode 100644 arch/arm/mach-uniphier/ph1-sld8/early_clkrst_init.c diff --git a/arch/arm/mach-uniphier/board_early_init_f.c b/arch/arm/mach-uniphier/board_early_init_f.c index bf81345..7108740 100644 --- a/arch/arm/mach-uniphier/board_early_init_f.c +++ b/arch/arm/mach-uniphier/board_early_init_f.c @@ -9,6 +9,7 @@ #include void pin_init(void);
