From a0a37183bd75e74608bc78c8d0e2a34454f95a91 Mon Sep 17 00:00:00 2001 From: pekon gupta Date: Thu, 8 May 2014 21:43:47 +0530 Subject: ARM: omap: merge GPMC initialization code for all platform GPMC controller on TI's OMAP SoC is general purpose controller to interface with different types of external devices like; - parallel NOR flash - parallel NAND flash - OneNand flash - SDR RAM - Ethernet Devices like LAN9220 Though GPMC configurations may be different for each platform depending on clock-frequency and external device interfacing with controller. But initialization sequence remains common across all platfoms. Thus this patch merges gpmc_init() scattered in different arch-xx/mem.c files into single omap-common/mem-common.c However, actual platforms specific register config values are still sourced from corresponding platform specific headers like; AM33xx: arch/arm/include/asm/arch-am33xx/mem.h OMAP3: arch/arm/include/asm/arch-omap3/mem.h OMAP4: arch/arm/include/asm/arch-omap4/mem.h OMAP4: arch/arm/include/asm/arch-omap5/mem.h Also, CONFIG_xx passed by board-profile decide config for which set of macros need to be used for initialization CONFIG_NAND: initialize GPMC for NAND device CONFIG_NOR: initialize GPMC for NOR device CONFIG_ONENAND: initialize GPMC for ONENAND device Signed-off-by: Pekon Gupta [trini: define GPMC_SIZE_256M for omap3] Signed-off-by: Tom Rini --- arch/arm/include/asm/arch-omap3/mem.h | 1 + 1 file changed, 1 insertion(+) (limited to 'arch/arm/include/asm/arch-omap3/mem.h') diff --git a/arch/arm/include/asm/arch-omap3/mem.h b/arch/arm/include/asm/arch-omap3/mem.h index 1804191..bdb1435 100644 --- a/arch/arm/include/asm/arch-omap3/mem.h +++ b/arch/arm/include/asm/arch-omap3/mem.h @@ -344,6 +344,7 @@ enum { * MAP - Map this CS to which address(GPMC address space)- Absolute address * >>24 before being used. */ +#define GPMC_SIZE_256M 0x0 #define GPMC_SIZE_128M 0x8 #define GPMC_SIZE_64M 0xC #define GPMC_SIZE_32M 0xE -- cgit v1.1
