[U-Boot] [PATCH] kbuild: clear VENDOR variable to fix build error on tcsh

23 Oct '14

Since the environment "VENDOR" is set in tcsh, it must be cleared in our makefile. Otherwise, boards without CONFIG_SYS_VENDOR fail to build: > make CROSS_COMPILE=arm-linux-gnueabi- wandboard_quad_defconfig all [ snip ] AR arch/arm/lib/lib.a CC arch/arm/lib/eabi_compat.o scripts/Makefile.build:55: /home/foo/u-boot/board/unknown/wandboard/ \ Makefile: No such file or directory make[2]: *** No rule to make target `/home/foo/u-boot/board/unknown/ \ wandboard/Makefile'.

[U-Boot] [PATCH 0/7] dm: Introduce driver model for Atmel at91
by Simon Glass 23 Oct '14

23 Oct '14

This series adds driver model support for serial and GPIO for the Atmel AT91 series. The at91sam9260-based Snapper 9260 is converted over as an example. For both drivers the old behaviour is retained, so driver model becomes option, not mandatory. This series is available at u-boot-dm/atmel-working.

[U-Boot] [PATCH v2 0/16] dm: Implement driver model support in SPL
by Simon Glass 23 Oct '14

23 Oct '14

Now that driver model operations prior to relocation, the remaining area where it does not work is SPL. This series enables this. Since SPL is quite memory-constrained, code and data size need to be kept as small as possible. This series includes a few changes to help with this: - Small and simple malloc() implementation - Dropping device removal features - Dropping stdio features - Dropping driver model warnings With these the code size impact of driver model is small, around 2-3KB. Data usage is typically 200-300 bytes. In many cases this can squeeze into the available SPL RAM space. This requires a revert of the SPL global_data revert (commit 1ee30ae). I believe that is planned for early in this merge window. We need that revert undone to be able to support the simple malloc in SPL on ARM. This series is available at u-boot-dm branch 'spl-working'. Changes in v2: - Correct the Makefile condition for simple_malloc - Rebase on top of the SPI series - Rebase to master Simon Glass (16): arm: spl: Avoid setting up a duplicate global data structure dm: dts: Move omap device tree includes to correct place dm: Split the simple malloc() implementation into its own file dm: arm: spl: Allow simple malloc() in SPL dm: spl: Make simple malloc() available when enabled dm: spl: Allow driver model to be used dm: Allow device removal features to be dropped dm: Allow stdio registration to be dropped dm: Disable dm_warn() in SPL dm: tegra: Add platform data for the SPL uart dm: tegra: Add platform data for the GPIO driver dm: arm: spl: Make driver model linker lists available dm: tegra: Enable driver model in SPL and adjust the GPIO driver dm: Update documentation to include CONFIG_DM... options WIP: Remove image tables in SPL (not to apply) skrink README | 119 +++++++++++++ arch/arm/cpu/u-boot-spl.lds | 7 + arch/arm/dts/dt-bindings/gpio/gpio.h | 15 -- arch/arm/lib/crt0.S | 2 +- arch/arm/lib/spl.c | 4 - board/nvidia/common/board.c | 8 + board/nvidia/seaboard/seaboard.c | 4 +- common/Makefile | 3 + common/board_r.c | 3 +- common/dlmalloc.c | 19 +-- common/image.c | 17 +- common/malloc_simple.c | 38 +++++ common/spl/spl.c | 16 +- doc/driver-model/README.txt | 44 +++-- drivers/core/Makefile | 3 +- drivers/core/device-remove.c | 187 +++++++++++++++++++++ drivers/core/device.c | 168 ------------------ drivers/gpio/Makefile | 4 + drivers/gpio/tegra_gpio.c | 27 ++- drivers/serial/serial-uclass.c | 8 +- drivers/serial/serial_tegra.c | 16 ++ include/asm-generic/global_data.h | 1 + include/config_defaults.h | 6 + include/configs/tegra-common.h | 19 +-- include/dm/device-internal.h | 10 ++ include/dm/util.h | 6 + .../dts => include}/dt-bindings/pinctrl/am33xx.h | 0 .../arm/dts => include}/dt-bindings/pinctrl/omap.h | 0 include/malloc.h | 60 ++++--- scripts/Makefile.spl | 1 + 30 files changed, 542 insertions(+), 273 deletions(-) delete mode 100644 arch/arm/dts/dt-bindings/gpio/gpio.h create mode 100644 common/malloc_simple.c create mode 100644 drivers/core/device-remove.c rename {arch/arm/dts => include}/dt-bindings/pinctrl/am33xx.h (100%) rename {arch/arm/dts => include}/dt-bindings/pinctrl/omap.h (100%) -- 2.1.0.rc2.206.gedb03e5

[U-Boot] [Question of dm serial] Is pending handler optional?
by Masahiro YAMADA 23 Oct '14

23 Oct '14

Hi Simon, I have questions of driver model serial. The comment block in include/serial.h states .pending is optional ---------------------------->8------------------------------- * pending() - Check if input/output characters are waiting * * This can be used to return an indication of the number of waiting * characters if the driver knows this (e.g. by looking at the FIFO * level). It is acceptable to return 1 if an indeterminant number * of characters is waiting. * * This method is optional. ----------------------------8<------------------------------- When I was testing my driver model conversion patch, I noticed ctrlc() function would not work without .pending handler. The function ctrlc() calls tstc() and if it returns non-zero value, it also calls getc(). If .pending handler is not implemented, tstc() function always return 1, even if no input character is available in UART FIFO; As a result, getc() function will get stuck in do { err = ops->getc(cur_dev); } while (err == -EAGAIN); loop. For example, "help" command does not work. So, .pending is mandatory, isn't it? One more question. The comment says .pending is: Check if input/output characters are waiting Should .pending check output buffer? or input only? -- Best Regards Masahiro Yamada

[U-Boot] [PATCH] dm: move platform data headers to include/dm/platform_data
by Masahiro Yamada 23 Oct '14

23 Oct '14

The platform_data structures are generally referenced from both drivers and board files. That is why header files defining platform_data sturectures are placed in "include" directory, but our top level "include" directory is already too cluttered. Let's collect platform_data definitions under the directory "include/dm/platform_data" as Linux gather them around under "include/linux/platform_data".
