This patchset adds support for ST's FSMC controller. In the current u-boot, a SPEAr specific driver exists for FSMC controller. This patchset adds a full fledged driver that can be used across multiple platforms and removes the obsolete SPEAr specific driver.
V4 -> V5 - Dropped the patch that defined change_bit as wrapper over __change_bit and, instead, used __change_bit directly in the driver code V3 -> V4 - Removed local_irq_save and local_irq_restore calls from change_bit wrapper - Report the total bit flips, including that of ECC, to the upper layers - Replace change_bit calls for err_idx's 0th and 1st bit with "^= 3" operation V2 -> V3 - Implemented timeout during hardware ecc read - Used __attribute__ ((aligned(2))) instead of using array of U16 - Removed unnecessary enum V1 -> V2 - Defined CONFIG_SYS_NAND_SELF_INIT and did the related changes - Modified the error index calculation process - Modified newly erased page read algorithm - Initialized the badblockbits index to 7 - Improved fsmc_bch8_correct_data() implementation Vipin KUMAR (3): mtd/NAND: Add FSMC driver support SPEAr: Configure FSMC driver for NAND interface mtd/NAND: Remove obsolete SPEAr specific NAND drivers arch/arm/include/asm/arch-spear/hardware.h | 8 +- arch/arm/include/asm/arch-spear/spr_nand.h | 57 ---- board/spear/spear300/spear300.c | 14 +- board/spear/spear310/spear310.c | 14 +- board/spear/spear320/spear320.c | 13 +- board/spear/spear600/spear600.c | 14 +- drivers/mtd/nand/Makefile | 1 + drivers/mtd/nand/fsmc_nand.c | 486 ++++++++++++++++++++++++++++ drivers/mtd/nand/spr_nand.c | 124 ------- include/configs/spear-common.h | 3 +- include/configs/spear3xx.h | 4 + include/configs/spear6xx.h | 3 + include/linux/mtd/fsmc_nand.h | 101 ++++++ 13 files changed, 637 insertions(+), 205 deletions(-) delete mode 100644 arch/arm/include/asm/arch-spear/spr_nand.h create mode 100644 drivers/mtd/nand/fsmc_nand.c delete mode 100644 drivers/mtd/nand/spr_nand.c create mode 100644 include/linux/mtd/fsmc_nand.h -- 1.7.2.2 _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
