[PATCH V3 0/6] add the GPMI controller driver for IMX23/IMX28
From: Huang Shijie <hidden>
Date: 2011-03-30 08:40:07
The general-purpose media interface(GPMI) controller is a flexible interface to up to several NAND flashs. The Bose Ray-Choudhury Hocquenghem(BCH) module is a hardware ECC accelerator. With the help of BCH, the GPMI controller can choose to do the hardware ECC or not. This driver is based the Shawn Guo's DMA patches for IMX23/IMX28, please refer to : http://git.infradead.org/users/vkoul/slave-dma.git/commit/a580b8c5429a624d120cd603e1498bf676e2b4da v2 --> v3: [0] merge the imx23 and imx28 into one file(including the header file). [1] remove the unuse registers in the headers. [2] fix DMA bugs [3] add bus width field to nand_attr{} [4] others v1 --> v2: [0] merge the common files into the gpmi-nfc-main.c [1] change the code to get the clock. [2] remove the timing in the nand_device_info{} [3] fix DMA errors [4] add the nand_device_info.[ch] to generic code [5] use the chip->onfi_version for the ONFI nand [6] useless init [7] others Huang Shijie (6): ARM: add GPMI support for imx23/imx28 dmaengine: change the flags of request_irq() MTD : add the database for the NANDs MTD : add the common code for GPMI controller driver MTD: add support for imx23 and imx28 MTD : add GPMI driver in the config and Makefile arch/arm/mach-mxs/Kconfig | 2 + arch/arm/mach-mxs/clock-mx23.c | 3 + arch/arm/mach-mxs/clock-mx28.c | 3 + arch/arm/mach-mxs/devices-mx23.h | 3 + arch/arm/mach-mxs/devices-mx28.h | 3 + arch/arm/mach-mxs/devices/Kconfig | 3 + arch/arm/mach-mxs/devices/Makefile | 1 + arch/arm/mach-mxs/devices/platform-gpmi.c | 140 ++ arch/arm/mach-mxs/include/mach/devices-common.h | 4 + arch/arm/mach-mxs/include/mach/gpmi-nfc.h | 62 + arch/arm/mach-mxs/mach-mx23evk.c | 37 + arch/arm/mach-mxs/mach-mx28evk.c | 37 + drivers/dma/mxs-dma.c | 2 +- drivers/mtd/nand/Kconfig | 10 + drivers/mtd/nand/Makefile | 1 + drivers/mtd/nand/gpmi-nfc/Makefile | 6 + drivers/mtd/nand/gpmi-nfc/bch-mx23-mx28.h | 88 + drivers/mtd/nand/gpmi-nfc/gpmi-mx23-mx28.h | 163 ++ drivers/mtd/nand/gpmi-nfc/gpmi-nfc-main.c | 2451 +++++++++++++++++++++++ drivers/mtd/nand/gpmi-nfc/gpmi-nfc.h | 549 +++++ drivers/mtd/nand/gpmi-nfc/hal-mx23-mx28.c | 562 ++++++ drivers/mtd/nand/gpmi-nfc/rom-mx23.c | 300 +++ drivers/mtd/nand/gpmi-nfc/rom-mx28.c | 66 + drivers/mtd/nand/nand_device_info.c | 157 ++ drivers/mtd/nand/nand_device_info.h | 88 + 25 files changed, 4740 insertions(+), 1 deletions(-) create mode 100644 arch/arm/mach-mxs/devices/platform-gpmi.c create mode 100644 arch/arm/mach-mxs/include/mach/gpmi-nfc.h create mode 100644 drivers/mtd/nand/gpmi-nfc/Makefile create mode 100644 drivers/mtd/nand/gpmi-nfc/bch-mx23-mx28.h create mode 100644 drivers/mtd/nand/gpmi-nfc/gpmi-mx23-mx28.h create mode 100644 drivers/mtd/nand/gpmi-nfc/gpmi-nfc-main.c create mode 100644 drivers/mtd/nand/gpmi-nfc/gpmi-nfc.h create mode 100644 drivers/mtd/nand/gpmi-nfc/hal-mx23-mx28.c create mode 100644 drivers/mtd/nand/gpmi-nfc/rom-mx23.c create mode 100644 drivers/mtd/nand/gpmi-nfc/rom-mx28.c create mode 100644 drivers/mtd/nand/nand_device_info.c create mode 100644 drivers/mtd/nand/nand_device_info.h
