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 <pekon@ti.com> [trini: define GPMC_SIZE_256M for omap3] Signed-off-by: Tom Rini <trini@ti.com>
