From 198a97a6abe7090109002baea0d2cb46070955aa Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Fri, 27 Feb 2015 02:26:51 +0900 Subject: 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/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 + 3 files changed, 19 insertions(+), 8 deletions(-) create mode 100644 arch/arm/mach-uniphier/ph1-ld4/early_clkrst_init.c (limited to 'arch/arm/mach-uniphier/ph1-ld4') diff --git a/arch/arm/mach-uniphier/ph1-ld4/Makefile b/arch/arm/mach-uniphier/ph1-ld4/Makefile index 72f46636fd..927640afd4 100644 --- a/arch/arm/mach-uniphier/ph1-ld4/Makefile +++ b/arch/arm/mach-uniphier/ph1-ld4/Makefile @@ -4,10 +4,10 @@ ifdef CONFIG_SPL_BUILD obj-$(CONFIG_DEBUG_LL) += lowlevel_debug.o -obj-y += bcu_init.o sbc_init.o sg_init.o pll_init.o clkrst_init.o \ +obj-y += bcu_init.o sbc_init.o sg_init.o pll_init.o early_clkrst_init.o \ pll_spectrum.o umc_init.o ddrphy_init.o else -obj-$(CONFIG_BOARD_EARLY_INIT_F) += pinctrl.o +obj-$(CONFIG_BOARD_EARLY_INIT_F) += pinctrl.o clkrst_init.o obj-$(if $(CONFIG_OF_CONTROL),,y) += platdevice.o endif diff --git a/arch/arm/mach-uniphier/ph1-ld4/clkrst_init.c b/arch/arm/mach-uniphier/ph1-ld4/clkrst_init.c index eaa45f94d3..f5fc418ef0 100644 --- a/arch/arm/mach-uniphier/ph1-ld4/clkrst_init.c +++ b/arch/arm/mach-uniphier/ph1-ld4/clkrst_init.c @@ -1,11 +1,10 @@ /* - * Copyright (C) 2011-2014 Panasonic Corporation + * Copyright (C) 2011-2015 Panasonic Corporation * Author: Masahiro Yamada * * SPDX-License-Identifier: GPL-2.0+ */ -#include #include #include @@ -15,15 +14,26 @@ void clkrst_init(void) /* deassert reset */ tmp = readl(SC_RSTCTRL); - tmp |= SC_RSTCTRL_NRST_ETHER | SC_RSTCTRL_NRST_UMC1 - | SC_RSTCTRL_NRST_UMC0 | SC_RSTCTRL_NRST_NAND; +#ifdef CONFIG_UNIPHIER_ETH + tmp |= SC_RSTCTRL_NRST_ETHER; +#endif +#ifdef CONFIG_NAND_DENALI + tmp |= SC_RSTCTRL_NRST_NAND; +#endif writel(tmp, SC_RSTCTRL); readl(SC_RSTCTRL); /* dummy read */ /* privide clocks */ tmp = readl(SC_CLKCTRL); - tmp |= SC_CLKCTRL_CEN_ETHER | SC_CLKCTRL_CEN_MIO | SC_CLKCTRL_CEN_UMC - | SC_CLKCTRL_CEN_NAND | SC_CLKCTRL_CEN_SBC | SC_CLKCTRL_CEN_PERI; +#ifdef CONFIG_UNIPHIER_ETH + tmp |= SC_CLKCTRL_CEN_ETHER; +#endif +#ifdef CONFIG_USB_EHCI_UNIPHIER + tmp |= SC_CLKCTRL_CEN_MIO; +#endif +#ifdef CONFIG_NAND_DENALI + tmp |= SC_CLKCTRL_CEN_NAND; +#endif writel(tmp, SC_CLKCTRL); readl(SC_CLKCTRL); /* dummy read */ } diff --git a/arch/arm/mach-uniphier/ph1-ld4/early_clkrst_init.c b/arch/arm/mach-uniphier/ph1-ld4/early_clkrst_init.c new file mode 100644 index 0000000000..d7ef16b10a --- /dev/null +++ b/arch/arm/mach-uniphier/ph1-ld4/early_clkrst_init.c @@ -0,0 +1 @@ +#include "../ph1-pro4/early_clkrst_init.c" -- cgit v1.2.1
