This series adds some necessary framework for IMX6 SPL support. The series includes support for NAND SPL and has been tested with MMC as well. I have tested this on five differing Ventana baseboards with a variety of memory (32bit 512MB, 32bit 1024MB, 64bit 1024MB) and CPU configurations (IMX6Q, IMX6DL, IMX6S).
v2: - use compatible linker script instead of creating new one - remove structure passing data from SPL to u-boot - remove dependence on mtdpart, mtdcore, nand_util, nand_ecc, nand_base and nand_bbt to bring SPL down in size. This reduced codesize by about 32k where now mxs_spl_nand is about 12k total - adjust CONFIG_SPL_TEXT_BASE, CONFIG_SPL_STACK and CONFIG_SPL_MAX_SIZE to accomodate the IMX6SOLO/DUALLITE which have half the iRAM of the IMX6DUAL/IMX6QUAD - move boot dev detection into imx-common/spl.c - move macros for using pinmux array into iomux-v3.h - remove missing/unnecessary include - revert mtdparts change - use get_ram_size() to detect memory - add support for MX6SOLO and MX6DUAL - set CS0_END for 4GB so get_ram_size() works - updated DDR3 calibration values for ventana boards - fixed build issue - only compile spl if doing spl build - fixed line length issue in README - remove CONFIG_SPL* conditions and conditionally compile instead - removed prints for CPU type and DRAM size/width - uboot will print these l - removed unused gw_ventana_spl.cfg - use common read_eeprom function - added MMC support to SPL - added Masahiro Yamada's boot mode consolidation patch http://patchwork.ozlabs.org/patch/341817 and rebase on top of it Masahiro Yamada (1): spl: consolidate arch/arm/include/asm/arch-*/spl.h Tim Harvey (11): SPL: NAND: remove CONFIG_SYS_NAND_PAGE_SIZE SPL: NAND: add support for mxs nand MX6: add common SPL configuration MX6: add boot device support for SPL IMX: add comments and remove unused struct fields MX6: add structs for mmdc and ddr iomux registers MX6: add mmdc configuration for MX6Q/MX6DL IMX: add additional function for pinmux using an array imx: ventana: split read_eeprom into standalone file imx: ventana: auto-configure for IMX6Q vs IMX6DL imx: ventana: switch to SPL arch/arm/cpu/arm720t/tegra-common/spl.c | 2 +- arch/arm/cpu/armv7/mx6/Makefile | 1 + arch/arm/cpu/armv7/mx6/ddr.c | 469 ++++++++++++++++++++++ arch/arm/imx-common/Makefile | 1 + arch/arm/imx-common/cpu.c | 16 +- arch/arm/imx-common/iomux-v3.c | 19 +- arch/arm/imx-common/spl.c | 79 ++++ arch/arm/include/asm/arch-at91/spl.h | 24 -- arch/arm/include/asm/arch-davinci/spl.h | 16 - arch/arm/include/asm/arch-mx35/spl.h | 22 -- arch/arm/include/asm/arch-mx5/spl.h | 13 - arch/arm/include/asm/arch-mx6/mx6-ddr.h | 231 +++++++++++ arch/arm/include/asm/arch-tegra114/spl.h | 22 -- arch/arm/include/asm/arch-tegra124/spl.h | 13 - arch/arm/include/asm/arch-tegra20/spl.h | 12 - arch/arm/include/asm/arch-tegra30/spl.h | 12 - arch/arm/include/asm/imx-common/iomux-v3.h | 15 + arch/arm/include/asm/spl.h | 20 + board/denx/m53evk/m53evk.c | 2 +- board/gateworks/gw_ventana/Makefile | 3 +- board/gateworks/gw_ventana/README | 92 +++-- board/gateworks/gw_ventana/eeprom.c | 89 +++++ board/gateworks/gw_ventana/gw_ventana.c | 591 +++++++++++++++------------- board/gateworks/gw_ventana/gw_ventana.cfg | 15 - board/gateworks/gw_ventana/gw_ventana_spl.c | 407 +++++++++++++++++++ board/gateworks/gw_ventana/ventana_eeprom.h | 11 + boards.cfg | 6 +- common/spl/spl_nand.c | 2 +- drivers/mtd/nand/Makefile | 1 + drivers/mtd/nand/mxs_nand_spl.c | 239 +++++++++++ include/configs/gw_ventana.h | 11 + include/configs/imx6_spl.h | 71 ++++ 32 files changed, 2050 insertions(+), 477 deletions(-) create mode 100644 arch/arm/cpu/armv7/mx6/ddr.c create mode 100644 arch/arm/imx-common/spl.c delete mode 100644 arch/arm/include/asm/arch-at91/spl.h delete mode 100644 arch/arm/include/asm/arch-davinci/spl.h delete mode 100644 arch/arm/include/asm/arch-mx35/spl.h delete mode 100644 arch/arm/include/asm/arch-mx5/spl.h delete mode 100644 arch/arm/include/asm/arch-tegra114/spl.h delete mode 100644 arch/arm/include/asm/arch-tegra124/spl.h delete mode 100644 arch/arm/include/asm/arch-tegra20/spl.h delete mode 100644 arch/arm/include/asm/arch-tegra30/spl.h create mode 100644 board/gateworks/gw_ventana/eeprom.c create mode 100644 board/gateworks/gw_ventana/gw_ventana_spl.c create mode 100644 drivers/mtd/nand/mxs_nand_spl.c create mode 100644 include/configs/imx6_spl.h -- 1.8.3.2 _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
