From mboxrd@z Thu Jan 1 00:00:00 1970 From: Amit Virdi Date: Mon, 27 Feb 2012 15:08:23 +0530 Subject: [U-Boot] [PATCH 2/3] SPEAr: Configure FSMC driver for NAND interface In-Reply-To: <1330335504-32226-1-git-send-email-amit.virdi@st.com> References: <1330335504-32226-1-git-send-email-amit.virdi@st.com> Message-ID: <1330335504-32226-3-git-send-email-amit.virdi@st.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de From: Vipin KUMAR Since FSMC is a standard IP and it supports different memory interfaces, it is supported independent of spear platform and spear is configured to use that driver for interfacing with the NAND device Signed-off-by: Vipin Kumar Signed-off-by: Amit Virdi --- arch/arm/include/asm/arch-spear/hardware.h | 8 ++++---- board/spear/spear300/spear300.c | 7 ++++--- board/spear/spear310/spear310.c | 7 ++++--- board/spear/spear320/spear320.c | 7 ++++--- board/spear/spear600/spear600.c | 7 ++++--- include/configs/spear-common.h | 2 +- include/configs/spear3xx.h | 4 ++++ include/configs/spear6xx.h | 3 +++ 8 files changed, 28 insertions(+), 17 deletions(-) diff --git a/arch/arm/include/asm/arch-spear/hardware.h b/arch/arm/include/asm/arch-spear/hardware.h index 818f36c..a6517b2 100644 --- a/arch/arm/include/asm/arch-spear/hardware.h +++ b/arch/arm/include/asm/arch-spear/hardware.h @@ -37,15 +37,15 @@ #if defined(CONFIG_SPEAR600) #define CONFIG_SYS_I2C_BASE (0xD0200000) -#define CONFIG_SPEAR_FSMCBASE (0xD1800000) +#define CONFIG_SYS_FSMC_BASE (0xD1800000) #elif defined(CONFIG_SPEAR300) #define CONFIG_SYS_I2C_BASE (0xD0180000) -#define CONFIG_SPEAR_FSMCBASE (0x94000000) +#define CONFIG_SYS_FSMC_BASE (0x94000000) #elif defined(CONFIG_SPEAR310) #define CONFIG_SYS_I2C_BASE (0xD0180000) -#define CONFIG_SPEAR_FSMCBASE (0x44000000) +#define CONFIG_SYS_FSMC_BASE (0x44000000) #undef CONFIG_SYS_NAND_CLE #undef CONFIG_SYS_NAND_ALE @@ -57,7 +57,7 @@ #elif defined(CONFIG_SPEAR320) #define CONFIG_SYS_I2C_BASE (0xD0180000) -#define CONFIG_SPEAR_FSMCBASE (0x4C000000) +#define CONFIG_SYS_FSMC_BASE (0x4C000000) #define CONFIG_SPEAR_EMIBASE (0x40000000) #define CONFIG_SPEAR_RASBASE (0xB3000000) diff --git a/board/spear/spear300/spear300.c b/board/spear/spear300/spear300.c index 60ee544..32bcb77 100644 --- a/board/spear/spear300/spear300.c +++ b/board/spear/spear300/spear300.c @@ -24,10 +24,10 @@ #include #include #include +#include #include #include #include -#include int board_init(void) { @@ -46,13 +46,14 @@ int board_nand_init(struct nand_chip *nand) struct misc_regs *const misc_regs_p = (struct misc_regs *)CONFIG_SPEAR_MISCBASE;
