From 6f2f01b9f30c390f216a065c8673c2c6933c0cbf Mon Sep 17 00:00:00 2001 From: Scott Wood Date: Thu, 20 Sep 2012 19:09:07 -0500 Subject: spl/nand: introduce CONFIG_SPL_NAND_DRIVERS, _BASE, and _ECC. Some small SPLs do not use nand_base.c, and a subset of those also require a special driver. Some SPLs need software ECC but others can't fit it. All existing boards that specify CONFIG_SPL_NAND_SUPPORT have these symbols added to preserve existing behavior. Signed-off-by: Scott Wood -- v2: use positive logic for including bits of NAND, rather than a MINIMAL symbol that excludes things. --- drivers/mtd/nand/Makefile | 30 ++++++++++++++++++++++-------- 1 file changed, 22 insertions(+), 8 deletions(-) (limited to 'drivers/mtd') diff --git a/drivers/mtd/nand/Makefile b/drivers/mtd/nand/Makefile index beb99cacb6..d8a2dfc398 100644 --- a/drivers/mtd/nand/Makefile +++ b/drivers/mtd/nand/Makefile @@ -26,21 +26,33 @@ include $(TOPDIR)/config.mk LIB := $(obj)libnand.o ifdef CONFIG_CMD_NAND + ifdef CONFIG_SPL_BUILD -ifdef CONFIG_SPL_NAND_SIMPLE -COBJS-y += nand_spl_simple.o -endif -ifdef CONFIG_SPL_NAND_LOAD -COBJS-y += nand_spl_load.o + +ifdef CONFIG_SPL_NAND_DRIVERS +NORMAL_DRIVERS=y endif -else + +COBJS-$(CONFIG_SPL_NAND_SIMPLE) += nand_spl_simple.o +COBJS-$(CONFIG_SPL_NAND_LOAD) += nand_spl_load.o +COBJS-$(CONFIG_SPL_NAND_ECC) += nand_ecc.o +COBJS-$(CONFIG_SPL_NAND_BASE) += nand_base.o + +else # not spl + +NORMAL_DRIVERS=y + COBJS-y += nand.o COBJS-y += nand_bbt.o COBJS-y += nand_ids.o COBJS-y += nand_util.o -endif COBJS-y += nand_ecc.o COBJS-y += nand_base.o + +endif # not spl + +ifdef NORMAL_DRIVERS + COBJS-$(CONFIG_NAND_ECC_BCH) += nand_bch.o COBJS-$(CONFIG_NAND_ATMEL) += atmel_nand.o @@ -65,7 +77,9 @@ COBJS-$(CONFIG_NAND_SPEAR) += spr_nand.o COBJS-$(CONFIG_TEGRA_NAND) += tegra_nand.o COBJS-$(CONFIG_NAND_OMAP_GPMC) += omap_gpmc.o COBJS-$(CONFIG_NAND_PLAT) += nand_plat.o -endif + +endif # drivers +endif # nand COBJS := $(COBJS-y) SRCS := $(COBJS:.o=.c) -- cgit v1.2.1
