* kbuild: fix build rule of u-boot-spl.dtbMasahiro Yamada2016-02-08-2/+2
| | | | | | | | | | | | The build command of u-boot-spl.dtb is not constant, but dependent on CONFIG_OF_SPL_REMOVE_PROPS. Use $(call if_changed,...) so that the change of CONFIG_OF_SPL_REMOVE_PROPS is detected. Also, add tools/fdtgrep to the dependency to make sure u-boot-spl.dtb is generated by the up-to-date fdtgrep in case the tool is modified.

* fdt: Build an SPL binary without device treeSimon Glass2016-02-01-9/+16
| | | | | | | | | | | | | | At present u-boot-spl.bin holds the plain SPL binary without the device tree. This is somewhat annoying since you need either u-boot-spl.bin or u-boot-spl-dtb.bin depending on whether device tree is used. Adjust the build such that u-boot-spl.bin includes a device tree (if enabled), and the plain binary is in u-boot-spl-nodtb.bin. For now u-boot-spl-dtb.bin remains the same.

* Move all command code into its own directorySimon Glass2016-01-25-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | There are a lot of unrelated files in common, including all of the commands. Moving them into their own directory makes them easier to find and is more logical. Some commands include non-command code, such as cmd_scsi.c. This should be sorted out at some point so that the function can be enabled with or without the associated command. Unfortunately, with m68k I get this error: m68k: + M5329AFEE +arch/m68k/cpu/mcf532x/start.o: In function `_start': +arch/m68k/cpu/mcf532x/start.S:159:(.text+0x452): relocation truncated to fit: R_68K_PC16 against symbol `board_init_f' defined in .text.board_init_f section in common/built-in.o I hope someone can shed some light on what this means.

* linux/kconfig.h: add CPP macros useful for per-image config optionsMasahiro Yamada2015-08-18-0/+26

Per-image config option control is a PITA in C sources, too. Here are some macros useful in C/CPP expressions. CONFIG_IS_ENABLED(FOO) can be used as a shorthand for (!defined(CONFIG_SPL_BUILD) && defined(CONFIG_FOO)) || \ (defined(CONFIG_SPL_BUILD) && defined(CONFIG_SPL_FOO)) For example, it is useful to describe C code as follows, #if CONFIG_IS_ENABLED(OF_CONTROL) (device tree code) #else (board file code) #endif The ifdef conditional above is switched by CONFIG_OF_CONTROL during the U-Boot proper building (CONFIG_SPL_BUILD is not defined), and by CONFIG_SPL_OF_CONTROL during SPL building (CONFIG_SPL_BUILD is defined). The macro can be used in C context as well, so you can also write the equivalent code as follows: if (CONFIG_IS_ENABLED(OF_CONTROL)) { (device tree code) } else { (board file code) } Another useful macro is CONFIG_VALUE(). CONFIG_VALUE(FOO) is expanded into CONFIG_FOO if CONFIG_SPL_BUILD is undefined, and into CONFIG_SPL_FOO if CONFIG_SPL_BUILD is defined. You can write as follows: text_base = CONFIG_VALUE(TEXT_BASE); instead of: #ifdef CONFIG_SPL_BUILD text_base = CONFIG_SPL_TEXT_BASE; #else text_base = CONFIG_TEXT_BASE; #endif This commit also adds slight hacking on fixdep so that it can output a correct list of fixed dependencies. If the fixdep finds CONFIG_IS_ENABLED(FOO) in a source file, we want $(wildcard include/config/foo.h) in the U-boot proper building context, while we want $(wildcard include/config/spl/foo.h) in the SPL build context.

* kbuild: add a makefile macro useful with per-image config optionsMasahiro Yamada2015-08-18-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit e02ee2548afe ("kconfig: switch to single .config configuration") made the configuration itself pretty simple, instead, we lost the way to systematically enable/disable config options for each image independently. Our current strategy is, put entries into Makefile.spl for options we need separate enabling, or once enable the options globally in Kconfig and then undef them in Makefile.uncmd_spl if we do not want to compile the features for SPL at all. Things are getting really messy. Besides, "ifdef CONFIG_SPL_BUILD" are sprinkled everywhere in makefiles. This commit adds a variable to help describe makefile simpler. $(SPL_) evaluates to "SPL_" during the SPL build, while to an empty string during building U-boot proper. So, you can write obj-$(CONFIG_$(SPL_)FOO) += foo.o instead of ifdef CONFIG_SPL_BUILD obj-$(CONFIG_SPL_FOO) += foo.o else obj-$(CONFIG_FOO) += foo.o endif If CONFIG_SPL_FOO does not exist in Kconfig, it is equivalent to ifndef CONFIG_SPL_BUILD obj-$(CONFIG_SPL_FOO) += foo.o endif This is the pattern we often see in our current makefiles. To take advantage of this macro, we should prefix SPL_ for the SPL version of the option when we need independent control between U-boot and SPL. With this naming scheme, I hope our makefiles will be much simplified. It means we want to rename existing config options as follows in the long run: CONFIG_SPL_SERIAL_SUPPORT -> CONFIG_SPL_SERIAL CONFIG_SPL_I2C_SUPPORT -> CONFIG_SPL_I2C CONFIG_SPL_GPIO_SUPPORT -> CONFIG_SPL_GPIO CONFIG_SPL_SPI_SUPPORT -> CONFIG_SPL_SPI CONFIG_SPL_DISABLE_OF_CONTROL -> CONFIG_SPL_OF_CONTROL (inverting the logic) Then drivers/Makefile would be re-worked as follows: obj-$(CONFIG_$(SPL_)SERIAL) += serial/ obj-$(CONFIG_$(SPL_)I2C) += i2c/ obj-$(CONFIG_$(SPL_)GPIO) += gpio/ obj-$(CONFIG_$(SPL_)SPI) += spi/ ... Eventually, SPL-specialized entries in Makefile.spl would go away.

| * arm: mvebu: Add Armada 38x DDR3 training code from Marvell bin_hdrStefan Roese2015-07-23-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds the DDR3 setup and training code taken from the Marvell U-Boot repository. This code used to be included as a binary (bin_hdr) into the Armada A38x boot image. Not linked with the main U-Boot. With this code addition and the serdes/PHY setup code, the Armada A38x support in mainline U-Boot is finally self-contained. So the complete image for booting can be built from mainline U-Boot. Without any additional external inclusion. Note: This code has undergone many hours (days!) of coding-style cleanup and refactoring. It still is not checkpatch clean though, I'm afraid. As the factoring of the code has so many levels of indentation that many lines are longer than 80 chars. Signed-off-by: Stefan Roese <sr@denx.de>

To support multiple Marvell DDR controller. This will be the new structure: drivers/ddr/marvell/axp Supporting Armada XP (AXP) devices (and perhaps Armada 370) drivers/ddr/marvell/a38x Supporting Armada 38x devices (and perhaps Armada 39x) Signed-off-by: Stefan Roese <sr@denx.de>
* | dm: Add a clock uclassSimon Glass2015-07-21-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Clocks are an important feature of platforms and have become increasing complex with time. Most modern SoCs have multiple PLLs and dozens of clock dividers which distribute clocks to on-chip peripherals. Some SoC implementations have a clock API which is private to that SoC family, e.g. Tegra and Exynos. This is useful but it would be better to have a common API that can be understood and used throughout U-Boot. Add a simple clock API as a starting point. It supports querying and setting the rate of a clock. Each clock is a device. To reduce memory and processing overhead the concept of peripheral clocks is provided. These do not need to be explicit devices - it is possible to write a driver that can adjust the I2C clock (for example) without an explicit I2C clock device. This can dramatically reduce the number of devices (and associated overhead) in a complex SoC. Clocks are referenced by a number, and it is expected that SoCs will define that numbering themselves via an enum. Signed-off-by: Simon Glass <sjg@chromium.org>

* | dm: Add support for LEDsSimon Glass2015-07-21-0/+1
| | | | | | | | | | | | | | | | | | Add a simple uclass for LEDs, so that these can be controlled by the device tree and activated when needed. LEDs are referred to by their label.

* | dm: Reduce SPL device tree sizeSimon Glass2015-07-21-0/+28
|/ | | | | | | | | The SPL device tree size must be minimised to save memory.

* Kconfig: Enable usage of escape char '\' in string valuesStefan Roese2015-06-08-54/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I might have missed something, but I failed to use the escape char '\' in strings. To pass a printf format string like "foo %d bar\n" via Kconfig to the code. Right now its not possible to use the escape character '\' in Kconfig string values correctly to e.g. set this string value "test output\n". The '\n' will be converted to 'n'. The current implementation removes some of the '\' chars from the input string in conf_set_sym_val(). Examples: '\' -> '' '\\' -> '\' '\\\' -> '\' '\\\\' -> '\\' ... And then doubles the backslash chars in the output string in sym_escape_string_value(). Example: '\' -> '' -> '' '\\' -> '\' -> '\\' '\\\' -> '\' -> '\\' '\\\\' -> '\\' -> '\\\\' ... As you see in these examples, its impossible to generate a single '\' charater in the output string as its needed for something like '\n'. This patch now changes this behavior to not drop some backslashes in conf_set_sym_val() and to not add new backslashes in the resulting output string. Removing the function sym_escape_string_value() completely as its not needed anymore.

* moveconfig: Ignore duplicate configs when movingJoe Hershberger2015-05-27-1/+2
| | | | | | | | | | | | | | | | | When moving configs, it is important to know what was defined in the config header even if it duplicates the configs coming from Kconfig. This is specifically needed for the case where a config is set to default 'y' in the Kconfig. This would previously cause the actual value from the include config to be filtered out, and moveconfig.py would think that it was 'n'... This means that the value that should be 'y' is now (in every defconfig) set to 'not set'. tools/moveconfig.py now defines KCONFIG_IGNORE_DUPLICATES to prevent the filtering from happening and selecting wrong values for the defconfig.
