This is a basic driver for the sunxi NAND controller for Allwinner A20. It supports only SPL.
The driver uses DMA for data transfers. It does not support writing. Changes in v2: - removed traces of non-SPL-specific code - moved the driver from boards/sunxi to drivers/mtd/nand - moved magic values to defines (whenever possible) - removed unnecesary late initialisation code - code style changes as suggested for the first patch set: - changed visibility of some symbols - renamed unclear variables - renamed header protector - changed types of pointer variables - other minor changes - renamed defines to be more relevant - moved Kconfig entry for the driver to drivers/mtd/nand - reworded Kconfig entry help Piotr Zierhoffer (3): sunxi: nand: Add basic sunxi NAND driver for SPL with DMA support sunxi: nand: Add board configuration options sunxi: nand: Add information to sunxi that it was run from NAND in SPL arch/arm/cpu/armv7/sunxi/board.c | 4 + drivers/mtd/nand/Kconfig | 7 + drivers/mtd/nand/Makefile | 1 + drivers/mtd/nand/sunxi_nand.c | 289 +++++++++++++++++++++++++++++++++++++++ drivers/mtd/nand/sunxi_nand.h | 151 ++++++++++++++++++++ include/configs/sunxi-common.h | 11 ++ 6 files changed, 463 insertions(+) create mode 100644 drivers/mtd/nand/sunxi_nand.c create mode 100644 drivers/mtd/nand/sunxi_nand.h -- 2.3.6 _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
