This series adds NAND flash support to Tegra and enables it on Seaboard. Included here is a proposed device tree binding with most of the properties private to "nvidia,". The binding includes information about the NAND controller as well as the connected NAND device. The Seaboard has a Hynix HY27UF4G2B.
The driver supports ECC-based access and uses DMA and NAND acceleration features of the Tegra SOC to provide access at reasonable speed. Changes in v2: - Add new patch to align default buffers in nand_base - Added comment about the behaviour of the 'resp' register - Call set_bus_width_page_size() at init to report errors earlier - Change set_bus_width_page_size() to return an error when needed - Change timing structure member to u32 to match device tree - Check for supported bus width in board_nand_init() - Fix tegra nand header file to remove BIT defines - Implement a dummy nand_select_chip() instead of nand_hwcontro() - Make nand_command() display an error on an unknown command - Minor code tidy-ups in driver for style - Move cache logic into a separate dma_prepare() function - Remove CMD_TRANS_SIZE_BYTESx enum - Remove space after casts - Remove use of 'register' variables - Rename struct nand_info to struct nand_drv to avoid nand_info_t confusion - Support 4096 byte page devices, drop 1024 and 2048 - Tidy up nand_waitfor_cmd_completion() logic - Update NAND binding to add "nvidia," prefix - Use s32 for device tree integer values Jim Lin (1): tegra: nand: Add Tegra NAND driver Simon Glass (6): nand: Try to align the default buffers fdt: Add debugging to fdtdec_get_int/addr() tegra: Add NAND support to funcmux tegra: fdt: Add NAND controller binding and definitions tegra: fdt: Add NAND definitions to fdt tegra: Enable NAND on Seaboard arch/arm/cpu/armv7/tegra2/funcmux.c | 7 + arch/arm/dts/tegra20.dtsi | 6 + arch/arm/include/asm/arch-tegra2/funcmux.h | 3 + arch/arm/include/asm/arch-tegra2/tegra2.h | 1 + board/nvidia/dts/tegra2-seaboard.dts | 15 + doc/device-tree-bindings/nand/nvidia-nand.txt | 68 ++ drivers/mtd/nand/Makefile | 1 + drivers/mtd/nand/nand_base.c | 3 +- drivers/mtd/nand/tegra2_nand.c | 1094 +++++++++++++++++++++++++ drivers/mtd/nand/tegra2_nand.h | 257 ++++++ include/configs/seaboard.h | 9 + include/fdtdec.h | 1 + include/linux/mtd/nand.h | 7 +- lib/fdtdec.c | 23 +- 14 files changed, 1485 insertions(+), 10 deletions(-) create mode 100644 doc/device-tree-bindings/nand/nvidia-nand.txt create mode 100644 drivers/mtd/nand/tegra2_nand.c create mode 100644 drivers/mtd/nand/tegra2_nand.h -- 1.7.7.3 _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
