[U-Boot] [PATCH v2 0/8] Extend LPC32xx functionality and add LPC32xx-based work_92015 board
by Albert ARIBAUD (3ADEV) 31 Mar '15

31 Mar '15

This series extends functionality for the LPC32xx platform and introduces the WORK Microwave work_92105 board which makes use of the extended functionality. NOTES: The series is not entirely checkpatch-clean. The following warnings and checks were not fixed: 1. "warning: arch/arm/Kconfig,241: please write a paragraph that describes the config symbol fully" Other symbols in the same file have no description either. For consistency, I did not add the requested description. 1. "check: include/configs/work_92105.h,177: spaces required around that ':' (ctx:VxV) (5 occurrences on the same line) This is due to the value of CONFIG_ETHADDR not being in quotes. As it never is in any other definition of CONFIG_ETHADDR, I left it unchanged. Changes in v2: - move from legacy to Driver Model support - added MUX setting for SSP0 - cosmetic: added a blank line before copyright - move boot image generation to mkimage framework Albert ARIBAUD (3ADEV) (8): lpc32xx: add Ethernet support lpc32xx: mtd: nand: add MLC NAND controller lpc32xx: i2c: add LPC32xx I2C interface support lpc32xx: add GPIO support lpc32xx: add LPC32xx SSP support (SPI mode) dtt: add ds620 support lpc32xx: add lpc32xx-spl.bin boot image target lpc32xx: add support for board work_92105 arch/arm/Kconfig | 6 + arch/arm/cpu/arm926ejs/lpc32xx/Makefile | 2 + arch/arm/cpu/arm926ejs/lpc32xx/clk.c | 34 ++ arch/arm/cpu/arm926ejs/lpc32xx/cpu.c | 13 + arch/arm/cpu/arm926ejs/lpc32xx/devices.c | 43 ++ arch/arm/cpu/arm926ejs/lpc32xx/dram.c | 80 +++ arch/arm/cpu/arm926ejs/lpc32xx/lowlevel_init.S | 45 ++ arch/arm/include/asm/arch-lpc32xx/clk.h | 16 + arch/arm/include/asm/arch-lpc32xx/config.h | 3 + arch/arm/include/asm/arch-lpc32xx/cpu.h | 3 + arch/arm/include/asm/arch-lpc32xx/gpio.h | 43 ++ arch/arm/include/asm/arch-lpc32xx/mux.h | 18 + arch/arm/include/asm/arch-lpc32xx/sys_proto.h | 8 +- board/work-microwave/work_92105/Kconfig | 15 + board/work-microwave/work_92105/MAINTAINERS | 6 + board/work-microwave/work_92105/Makefile | 8 + board/work-microwave/work_92105/README | 23 + board/work-microwave/work_92105/work_92105.c | 86 +++ .../work-microwave/work_92105/work_92105_display.c | 349 +++++++++++ .../work-microwave/work_92105/work_92105_display.h | 14 + common/image.c | 1 + configs/work_92105_defconfig | 5 + drivers/gpio/Makefile | 1 + drivers/gpio/lpc32xx_gpio.c | 268 +++++++++ drivers/hwmon/Makefile | 1 + drivers/hwmon/ds620.c | 65 +++ drivers/i2c/Makefile | 1 + drivers/i2c/lpc32xx_i2c.c | 249 ++++++++ drivers/mtd/nand/Makefile | 1 + drivers/mtd/nand/lpc32xx_nand_mlc.c | 589 +++++++++++++++++++ drivers/net/Makefile | 1 + drivers/net/lpc32xx_eth.c | 636 +++++++++++++++++++++ drivers/spi/Makefile | 1 + drivers/spi/lpc32xx_ssp.c | 132 +++++ include/configs/work_92105.h | 259 +++++++++ include/dtt.h | 15 +- include/image.h | 1 + include/netdev.h | 1 + scripts/Makefile.spl | 9 + tools/Makefile | 1 + tools/lpc32xximage.c | 178 ++++++ 41 files changed, 3222 insertions(+), 8 deletions(-) create mode 100644 arch/arm/cpu/arm926ejs/lpc32xx/dram.c create mode 100644 arch/arm/cpu/arm926ejs/lpc32xx/lowlevel_init.S create mode 100644 arch/arm/include/asm/arch-lpc32xx/gpio.h create mode 100644 arch/arm/include/asm/arch-lpc32xx/mux.h create mode 100644 board/work-microwave/work_92105/Kconfig create mode 100644 board/work-microwave/work_92105/MAINTAINERS create mode 100644 board/work-microwave/work_92105/Makefile create mode 100644 board/work-microwave/work_92105/README create mode 100644 board/work-microwave/work_92105/work_92105.c create mode 100644 board/work-microwave/work_92105/work_92105_display.c create mode 100644 board/work-microwave/work_92105/work_92105_display.h create mode 100644 configs/work_92105_defconfig create mode 100644 drivers/gpio/lpc32xx_gpio.c create mode 100644 drivers/hwmon/ds620.c create mode 100644 drivers/i2c/lpc32xx_i2c.c create mode 100644 drivers/mtd/nand/lpc32xx_nand_mlc.c create mode 100644 drivers/net/lpc32xx_eth.c create mode 100644 drivers/spi/lpc32xx_ssp.c create mode 100644 include/configs/work_92105.h create mode 100644 tools/lpc32xximage.c -- 2.1.0

[U-Boot] U-boot and UBI problem with vexpress board.
by Marcin Krzemiński 31 Mar '15

31 Mar '15

Hi, I want to test some UBI fs behavior in U-Boot using qemu and vexpress_ca9x4 board ( U-Boot 2015.1) To tst UBI I added lines to vexpress_ca9x4.h: #define CONFIG_MTD_DEVICE /* needed for mtdparts commands */ #define CONFIG_MTD_PARTITIONS /* needed for UBI */ #define CONFIG_FLASH_CFI_MTD #define MTDIDS_DEFAULT "nor0=flash0-0" #define MTDPARTS_DEFAULT "mtdparts=flash0-0:1m(empty),10m(ubi),-(rest)" #define CONFIG_LZO /* needed for UBI */ #define CONFIG_RBTREE /* needed for UBI */ #define CONFIG_CMD_MTDPARTS #define CONFIG_CMD_UBI #define CONFIG_CMD_UBIFS #define CONFIG_FIT also I've changed malloc pool size to 512kB in vexpress_common.h: #define CONFIG_SYS_MALLOC_LEN (CONFIG_ENV_SIZE + 512 * 1024) Also I enabled debugs in UBI and MTD driver I'm running my test commands like that: qemu-system-arm -M vexpress-a9 -kernel u-boot -m 1024M -nographic -pflash flash1.bin -pflash flash2.bin Than in u-boot console: mtd default ubi part ubi results are: UBI: attaching mtd2 to ubi0 UBI: scanning is finished UBI: empty MTD device detected UBI: attached mtd2 (name "mtd=1", size 10 MiB) to ubi0 UBI: PEB size: 524288 bytes (512 KiB), LEB size: 524160 bytes UBI: min./max.

I am quting qemu, starting it again ant now I can not mount ubi. Logs are here: UBI: attaching mtd2 to ubi0 UBI: scanning is finished UBI error: vtbl_check: bad CRC at record 0: 0x88cdfb6, not 0xffffffff UBI error: vtbl_check: bad CRC at record 0: 0x88cdfb6, not 0xffffffff UBI error: process_lvol: both volume tables are corrupted UBI error: ubi_attach_mtd_dev: failed to attach mtd2, error -22 UBI error: ubi_init: cannot attach mtd2 UBI error: ubi_init: cannot initialize UBI, error -22 ubi_init UBI init error 22 In flash imgae besides UBI! and UBI# headers I've got some other written sectors in this partition, is that ok? I thing i should have only those two headers ant their copy at this staete. I also thing about changing pool size, maybe there is something wrong with SP and that is why I've got this strange behaviour? I've tested qemu flash emulation, and all seems to work fine (writing and reading after reboots). Regards, Marcin

[U-Boot] [PATCH v4 0/25] tegra: Add eDP support for nyan-big
by Simon Glass 31 Mar '15

31 Mar '15

This series adds eDP support for nyan-big so that the display works. Nyan-big is based on tegra124. Some support is added for new clocks to make this work. The drm_dp_helper.h file is brought in from Linux since many of the DisplayPort constants are generic. A very simple uclass is added for DisplayPort, and the Tegra driver makes use of that. The U-Boot EDID support is enhanced to read some additional information (detailed timings). There is existing video support for Tegra20, but I don't think it works for Tegra30/114 (is this correct?). This series relies on detecting the display at run-time as I cannot find a good device tree binding for things like display depth. But if we could resolve that then it might be possible to move Tegra20 over to use the same driver, etc. There is clearly a lot in common with the display controllers - I have exploited this with the header file but not with the C file. HDMI is not supported at present. If this is easy and there is an existing driver to follow along with then I might be able to incorporate it later. This series is available at u-boot-dm/nyan-working Changes in v4: - Rebase on tegra/master since this series is still pending Changes in v3: - Add full link training support - Change parameters of update_display_mode() - Fix 64-bit maths error - Fix trainging typo - Reorder parameters to tegra_dc_sor_attach() - Set scramble_ena to 1 on start-up so that link training succeeds - Simplify timouts to remove repeated multiplication by 1000 - Use real error return values in tegra_dc_dpaux_write_chunk() and others - Use sor pointer in struct tegra_dp_priv Changes in v2: - Rebase on top of u-boot-dm - Remove definition of BIT() Simon Glass (25): dm: gpio: Add error handling and a function to claim vector GPIOs fdt: Add binding decode function for display-timings tegra: Move the pwm into tegra-common tegra: pwm: Allow the clock rate to be left as is tegra: Move checkboard() into the board code tegra: Add a board ID function power: Export register access functions from as3722 tegra: Provide a function to allow LCD PMIC setup tegra: Add support for setting up a as3722 PMIC tegra: nyan-big: Add LCD PMIC init and board ID tegra124: dts: Add host1x node to provide display information tegra: config: Use CONFIG_LCD to detect LCD presence tegra: clock: Add checking for invalid clock IDs tegra: clock: Split the clock source code into a separate function tegra124: clock: Add display clocks and functions tegra: Move display controller header into common video: Add drm_dp_helper.h edid: Add a function to read detailed monitor timings dm: video: Add a uclass for display port tegra: dts: nyan-big: Add definitions for eDP display tegra: video: Support serial output resource (SOR) on tegra124 tegra: video: Add Embedded DisplayPort driver tegra: video: support eDP displays on Tegra124 devices tegra: config: nyan-big: Enable LCD tegra124: video: Add full link training for eDP arch/arm/dts/tegra124-nyan-big.dts | 47 + arch/arm/dts/tegra124.dtsi | 84 + arch/arm/include/asm/arch-tegra/clk_rst.h | 15 +- arch/arm/include/asm/arch-tegra/clock.h | 14 + .../include/asm/{arch-tegra20 => arch-tegra}/dc.h | 67 +- arch/arm/include/asm/arch-tegra/pwm.h | 60 + arch/arm/include/asm/arch-tegra/sys_proto.h | 19 +- arch/arm/include/asm/arch-tegra124/clock-tables.h | 3 +- arch/arm/include/asm/arch-tegra124/clock.h | 21 + arch/arm/include/asm/arch-tegra124/display.h | 58 + arch/arm/include/asm/arch-tegra124/pwm.h | 14 + arch/arm/include/asm/arch-tegra20/display.h | 2 +- arch/arm/include/asm/arch-tegra20/pwm.h | 54 +- arch/arm/mach-tegra/Makefile | 1 + arch/arm/mach-tegra/board.c | 8 - arch/arm/mach-tegra/clock.c | 83 +- arch/arm/mach-tegra/{tegra20 => }/pwm.c | 7 +- arch/arm/mach-tegra/tegra124/clock.c | 141 +- arch/arm/mach-tegra/tegra20/Makefile | 1 - arch/arm/mach-tegra/tegra20/display.c | 2 +- board/nvidia/common/board.c | 40 +- board/nvidia/nyan-big/nyan-big.c | 34 +- common/edid.c | 105 ++ configs/nyan-big_defconfig | 2 + .../gpu/nvidia,tegra20-host1x.txt | 372 +++++ doc/device-tree-bindings/video/display-timing.txt | 110 ++ drivers/gpio/gpio-uclass.c | 38 +- drivers/power/as3722.c | 16 +- drivers/video/Kconfig | 15 + drivers/video/Makefile | 6 + drivers/video/dp-uclass.c | 34 + drivers/video/tegra124/Makefile | 10 + drivers/video/tegra124/display.c | 472 ++++++ drivers/video/tegra124/displayport.h | 412 +++++ drivers/video/tegra124/dp.c | 1599 ++++++++++++++++++++ drivers/video/tegra124/sor.c | 1019 +++++++++++++ drivers/video/tegra124/sor.h | 922 +++++++++++ drivers/video/tegra124/tegra124-lcd.c | 94 ++ include/asm-generic/gpio.h | 15 +- include/configs/nyan-big.h | 14 + include/configs/tegra-common-post.h | 2 +- include/displayport.h | 60 + include/dm/uclass-id.h | 1 + include/edid.h | 19 + include/fdtdec.h | 81 + include/linux/drm_dp_helper.h | 406 +++++ include/power/as3722.h | 3 + lib/fdtdec.c | 95 ++ 48 files changed, 6569 insertions(+), 128 deletions(-) rename arch/arm/include/asm/{arch-tegra20 => arch-tegra}/dc.h (89%) create mode 100644 arch/arm/include/asm/arch-tegra/pwm.h create mode 100644 arch/arm/include/asm/arch-tegra124/display.h create mode 100644 arch/arm/include/asm/arch-tegra124/pwm.h rename arch/arm/mach-tegra/{tegra20 => }/pwm.c (93%) create mode 100644 doc/device-tree-bindings/gpu/nvidia,tegra20-host1x.txt create mode 100644 doc/device-tree-bindings/video/display-timing.txt create mode 100644 drivers/video/dp-uclass.c create mode 100644 drivers/video/tegra124/Makefile create mode 100644 drivers/video/tegra124/display.c create mode 100644 drivers/video/tegra124/displayport.h create mode 100644 drivers/video/tegra124/dp.c create mode 100644 drivers/video/tegra124/sor.c create mode 100644 drivers/video/tegra124/sor.h create mode 100644 drivers/video/tegra124/tegra124-lcd.c create mode 100644 include/displayport.h create mode 100644 include/linux/drm_dp_helper.h -- 2.2.0.rc0.207.ga3a616c

[U-Boot] [PATCH] MAKEALL: fix get_target_arch() to adjust to '-' in Status field
by Masahiro Yamada 30 Mar '15

30 Mar '15

Since the Kconfig conversion, MAKEALL scans boards.cfg generated by tools/genboardscfg.py. Every board is supposed to have its own MAINTAINERS that contains maintainer and status information, but, in fact, MAINTAINERS is missing from some boards. For such boards, the first field, Status, is filled with '-'. It causes a problem for "set" command, which ignores '-' in its arguments. Consequently, get_target_arch() returns a wrong field and MAKEALL fails to get a correct toolchain.

And the OCR register value and the high capacity flag may be set incorrectly. So, this patch is not enough by itself, it needs to be modified (appended) in order to get the correct code. Coincidentally, the same day I submitted a patch series ("[U-Boot] [PATCH 0/6] mmc: Fix OCR polling and splitted initialization"), that, among other changes, fixes the OCR polling problem too ("[U-Boot] [PATCH 4/6] mmc: Continue polling MMC card for OCR only if it is still not ready"), but in a slightly different way, that hopefully doesn't have the mentioned issue. Thanks. Best regards, Andrew

The most important things done: [1] Separation of interrupt vectore tables from start.S [2] Merge of low-level start-up code (written in assembly) for ARCompat and ARCv2 architectures [3] Separation of interrupt and exception handling code in a separate source file (ints_low.S) [4] Major clean-up of start-up code and switch to heavy use of routines written in C (re-use implementations for x86 in board_f.c) Alexey Brodkin (6): arc: merge common start-up code between ARC and ARCv2 arc: move low-level interrupt and exception handlers in a separate file arc: clean-up init procedure arc: get rid of CONFIG_SYS_GENERIC_GLOBAL_DATA arc: minor fixes in Kconfig arc: re-generate defconfigs arch/arc/Kconfig | 10 +- arch/arc/cpu/arcv1/Makefile | 2 +- arch/arc/cpu/arcv1/ivt.S | 27 ++++ arch/arc/cpu/arcv1/start.S | 254 ------------------------------------ arch/arc/cpu/arcv2/Makefile | 2 +- arch/arc/cpu/arcv2/ivt.S | 27 ++++ arch/arc/cpu/arcv2/start.S | 254 ------------------------------------ arch/arc/include/asm/config.h | 1 - arch/arc/include/asm/init_helpers.h | 12 ++ arch/arc/include/asm/relocate.h | 16 +++ arch/arc/include/asm/u-boot-arc.h | 3 + arch/arc/lib/Makefile | 3 + arch/arc/lib/cpu.c | 13 -- arch/arc/lib/init_helpers.c | 27 ++++ arch/arc/lib/ints_low.S | 151 +++++++++++++++++++++ arch/arc/lib/relocate.c | 19 +++ arch/arc/lib/start.S | 51 ++++++++ common/board_f.c | 8 +- configs/arcangel4-be_defconfig | 4 +- configs/arcangel4_defconfig | 2 +- configs/axs101_defconfig | 6 +- configs/axs103_defconfig | 4 +- configs/tb100_defconfig | 4 +- 23 files changed, 361 insertions(+), 539 deletions(-) create mode 100644 arch/arc/cpu/arcv1/ivt.S delete mode 100644 arch/arc/cpu/arcv1/start.S create mode 100644 arch/arc/cpu/arcv2/ivt.S delete mode 100644 arch/arc/cpu/arcv2/start.S create mode 100644 arch/arc/include/asm/init_helpers.h create mode 100644 arch/arc/include/asm/relocate.h create mode 100644 arch/arc/lib/init_helpers.c create mode 100644 arch/arc/lib/ints_low.S create mode 100644 arch/arc/lib/start.S -- 2.1.0
