2014-10-23test: dm: Add additional GPIO testsSimon Glass
Add tests for gpio_requestf() and for memory leaks. Signed-off-by: Simon Glass <sjg@chromium.org>
2014-10-23test: dm: Support memory leak checking as a core featureSimon Glass
Check the state of the malloc() heap before each test is run, so that tests can verify that all is well at the end. Provide helper functions to mark the heap and to check that it returns to its initial state. Signed-off-by: Simon Glass <sjg@chromium.org>
2014-10-23dm: gpio: Add gpio_requestf() helper for printf() stringsSimon Glass
Add a helper which permits a printf()-style format string for the requester string. Signed-off-by: Simon Glass <sjg@chromium.org>
2014-10-23test: dm: Update GPIO tests for new gpio_request() methodSimon Glass

2014-10-23dm: gpio: sandbox: Implement the remove() methodSimon Glass
This method frees memory so we must make sure to implement it. Signed-off-by: Simon Glass <sjg@chromium.org>
2014-10-23dm: gpio: sandbox: Implement the get_function() methodSimon Glass
Implement this method so that the 'gpio' command can do its job correctly. For sandbox we only support input and output states for a gpio. Signed-off-by: Simon Glass <sjg@chromium.org>
2014-10-23dm: Move the function for getting GPIO status into the uclassSimon Glass
This function can be more easily tested if it is in the uclass. Signed-off-by: Simon Glass <sjg@chromium.org>
2014-10-23dm: gpio: Add gpio_get_function() and friendsSimon Glass
Add helpers to the uclass to allow finding out the pin function. Signed-off-by: Simon Glass <sjg@chromium.org>
2014-10-23dm: gpio: Implement GPIO reservation in the uclassSimon Glass
We have several GPIO drivers now and all are doing similar things to record which GPIOs are reserved. Move this logic into the uclass to make the drivers similar. We retain the request()/free() methods since currently one driver does use these for setting up the pin. Signed-off-by: Simon Glass <sjg@chromium.org>
2014-10-23dm: omap3: Move to driver model for GPIO and serialSimon Glass
Adjust the configuration for the am33xx boards, including beagleboard, to use driver model. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Tom Rini <trini@ti.com>
2014-10-23dm: am33xx: Move to driver model for GPIO and serialSimon Glass
Adjust the configuration for the am33xx boards, including beaglebone black to use driver model. This can be extended to other OMAP boards once platform data is provided for them. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Tom Rini <trini@ti.com>
2014-10-23dm: am335x: Remove serial options from CONFIG_SYS_EXTRA_OPTIONSSimon Glass
With these options in place it is not possible to change the serial port using 'make menuconfig' or similar. It seems to result in duplicate defines. For example: In file included from include/linux/kconfig.h:4:0, from <command-line>:0: include/generated/autoconf.h:20:0: note: this is the location of the previous definition #define CONFIG_CONS_INDEX 2 ^ The default option seems to be 1 anyway, in board/ti/am335x/Kconfig. Remove the options so that we can adjust the serial port if required. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Tom Rini <trini@ti.com>
2014-10-23dm: omap: serial: Add driver model supportSimon Glass

2014-10-23dm: omap: gpio: Support driver modelSimon Glass
Add driver model support to this driver, while retaining support for the legacy system. Driver model GPIO support is enabled with CONFIG_DM_GPIO as usual. Since gpio_is_valid() no longer exists, we can use the -EINVAL error returned from gpio_request(). Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@ti.com>
2014-10-23dm: omap: gpio: Put _get_gpio_value() logic into its own functionSimon Glass
Add a separate internal helper function to get a GPIO value, so that we will be able to call it with the driver model version and avoid code duplication. Also move gpio_get_bank() and check_gpio() down below the helper functions as these won't be needed with driver model.

Try to use this option to select the correct uart for the console. This mimics the behaviour of drivers/serial.c. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@ti.com>
2014-10-23dm: ns16550: Correct the probe logic for platform dataSimon Glass
The probe logic sets up the pointer to the platform data in the device tree decode method. It should be done in the probe() method, and anyway the device tree decode method can't be used when CONFIG_OF_CONTROL is not enabled. Fix these two problems. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@ti.com>
2014-10-23dm: ns16550: Use an address instead of a pointer for the uart baseSimon Glass
It is inconvenient to have to use casts when specifying platform data. Also it is not strictly correct, since we should use map_sysmem() to convert an address to a pointer. Adjust the platform data to use an address. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@ti.com>
2014-10-23dm: serial: ns16550: Correct logic for checking for characterSimon Glass
There is a bug in the logic which checks for an available character. This can cause invalid characters to be received - this was noticed on beaglebone. Fix it. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@ti.com>
2014-10-23dm: serial: Reset the watchdog while waiting in getc()Simon Glass
We have moved the busy-wait loop out of drivers and into the uclass. This means that we must reset the watchdog when busy-waiting. Note: some drivers may still have a busy-wait even with driver model, as a transition mechanism. Driver model will tolerate this, and is can be cleaned up when all users of the driver use driver model. An example is ns16550.

2014-10-23dm: gpio: Support numbered GPIOsSimon Glass
At present banks must be named and it is not possible to refer to GPIOs by number in driver model. Some boards use numbering - e.g. OMAP. It is fairly easy to support by detecting the absense of a bank name (which starts with a letter). Add support for numbered GPIOs in addition to the existing bank support.

2014-10-23mips: enable CONFIG_USE_PRIVATE_LIBGCC by defaultMasahiro Yamada
Without the private libgcc, we need a full multilib toolchain with different libgcc or multiple toolchains to build all BE/LE and hard-float/soft-float variants of MIPS boards. That is not feasible. This commit allows us to build all the MIPS boards with a single kernel.org toolchain: https://www.kernel.org/pub/tools/crosstool/files/bin/x86_64/4.9.0/ x86_64-gcc-4.9.0-nolibc_mips-linux.tar.xz This change sounds reasonable for most users. If necessary, you can disable this option via "make menuconfig" or friends. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Acked-by: Daniel Schwierzeck <daniel.schwierzeck@gmail.com>
2014-10-23kconfig: invoke silentoldconfig if spl, tpl/.config is updatedMasahiro Yamada
When spl/.config is updated by "make spl/menuconfig" or friends, spl/include/config/auto.conf, spl/include/generated/autoconf.h and some other files must be updated by "make silentoldconfig". There is no hook for SPL in the top Makefile, so this commit touches .config when spl/.config is updated to invoke silentoldconfig. Likewise for TPL.

2014-10-23kbuild: fix a bug of the u-boot-spl link ruleMasahiro Yamada
cmd_u-boot-spl includes $(PLATFORM_LIBS) which changes when CONFIG_USE_PRIVATE_GCC is updated. The u-boot-spl image should be re-linked if any prerequisite is newer than it or the command line has changed. $(call, if_changed,...) should be used instead of $(call cmd,...).

2014-10-23kconfig: move CONFIG_USE_PRIVATE_LIBGCC to KconfigMasahiro Yamada
The private libgcc is supported only on ARM, MIPS, PowerPC, SH, x86. Those architectures should "select" HAVE_PRIVATE_LIBGCC and CONFIG_USE_PRIVATE_LIBGCC should depend on it. Currently, this option is enabled on Tegra boards and x86 architecture. Move the definition from header files to Kconfig.

2014-10-23x86: set CONFIG_USE_PRIVATE_LIBGCC to yMasahiro Yamada
The motivation of this commit is to change CONFIG_USE_PRIVATE_LIBGCC to a boolean macro so we can move it to Kconfig. In the current implementation, there are two forms of syntax for this macro: - CONFIG_USE_PRIVATE_LIBGCC=y - CONFIG_USE_PRIVATE_LIBGCC=path/to/private/libgcc The latter is only used by x86 architecture. With a little bit refactoring, it can be converted to the former.

2014-10-23kconfig: move CONFIG_SYS_HZ to lib/KconfigMasahiro Yamada
CONFIG_SYS_HZ is always defined as 1000 in config_fallbacks.h (but some boards still have redundant definitions). This commit moves the definition and the document in README to Kconfig. Since lib/Kconfig can assure that CONFIG_SYS_HZ is 1000, the sanity check in lib/time.c should be removed.
