* x86: Generate a valid ACPI tableSaket Sinha2015-08-26-0/+11
| | | | | | | | | | | | | | | | | Implement write_acpi_table() to create a minimal working ACPI table. This includes writing FACS, XSDT, RSDP, FADT, MCFG, MADT, DSDT & SSDT ACPI table entries. Use a Kconfig option GENERATE_ACPI_TABLE to tell U-Boot whether we need actually write the APCI table just like we did for PIRQ routing, MP table and SFI tables. With ACPI table existence, linux kernel gets control of power management, thermal management, configuration management and monitoring in hardware.

* of: clean up OF_CONTROL ifdef conditionalsMasahiro Yamada2015-08-18-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | We have flipped CONFIG_SPL_DISABLE_OF_CONTROL. We have cleansing devices, $(SPL_) and CONFIG_IS_ENABLED(), so we are ready to clear away the ugly logic in include/fdtdec.h: #ifdef CONFIG_OF_CONTROL # if defined(CONFIG_SPL_BUILD) && !defined(SPL_OF_CONTROL) # define OF_CONTROL 0 # else # define OF_CONTROL 1 # endif #else # define OF_CONTROL 0 #endif Now CONFIG_IS_ENABLED(OF_CONTROL) is the substitute. It refers to CONFIG_OF_CONTROL for U-boot proper and CONFIG_SPL_OF_CONTROL for SPL. Also, we no longer have to cancel CONFIG_OF_CONTROL in include/config_uncmd_spl.h and scripts/Makefile.spl.

* of: flip CONFIG_SPL_DISABLE_OF_CONTROL into CONFIG_SPL_OF_CONTROLMasahiro Yamada2015-08-18-1/+1
| | | | | | | | | | | | | | | | | | | As we discussed a couple of times, negative CONFIG options make our life difficult; CONFIG_SYS_NO_FLASH, CONFIG_SYS_DCACHE_OFF, ... and here is another one. Now, there are three boards enabling OF_CONTROL on SPL: - socfpga_arria5_defconfig - socfpga_cyclone5_defconfig - socfpga_socrates_defconfig This commit adds CONFIG_SPL_OF_CONTROL for them and deletes CONFIG_SPL_DISABLE_OF_CONTROL from the other boards to invert the logic.

| | | | | | | | | | | | | | | We do not want to compile the DM remove code for SPL. Currently, we undef it in include/config_uncmd_spl.h (for C files) and in scripts/Makefile.uncmd_spl (for Makefiles). This is really ugly. This commit demonstrates how we can deprecate those two files. Use $(SPL_) for the entry in the Makfile and CONFIG_IS_ENABLED() in C files.

* linux/kconfig.h: add CPP macros useful for per-image config optionsMasahiro Yamada2015-08-18-0/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The previous commit introduced a useful macro used in makefiles, in order to reference to different variables (CONFIG_... or CONFIG_SPL_...) depending on the build context. 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* 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.

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.

There were actually two options, "single .config" and "multiple .config". After some discussions and thought experiments, I chose the latter, i.e. to create ".config", "spl/.config", "tpl/.config" for Normal, SPL, TPL, respectively. It is true that the "multiple .config" strategy provided us the maximum flexibility and helped to avoid duplicating CONFIGs among Normal, SPL, TPL, but I have noticed some fatal problems: [1] It is impossible to share CONFIG options across the images. If you change the configuration of Main image, you often have to adjust some SPL configurations correspondingly. Currently, we cannot handle the dependencies between them. It means one of the biggest advantages of Kconfig is lost. [2] It is too painful to change both ".config" and "spl/.config". Sunxi guys started to work around this problem by creating a new configuration target. Commit cbdd9a9737cc (sunxi: kconfig: Add %_felconfig rule to enable FEL build of sunxi platforms.) added "make *_felconfig" to enable CONFIG_SPL_FEL on both images. Changing the configuration of multiple images in one command is a generic demand. The current implementation cannot propose any good solution about this. [3] Kconfig files are getting ugly and difficult to understand. Commit b724bd7d6349 (dm: Kconfig: Move CONFIG_SYS_MALLOC_F_LEN to Kconfig) has sprinkled "if !SPL_BUILD" over the Kconfig files. [4] The build system got more complicated than it should be. To adjust Linux-originated Kconfig to U-Boot, the helper script "scripts/multiconfig.sh" was introduced. Writing a complicated text processor is a shell script sometimes caused problems. Now I believe the "single .config" will serve us better. With it, all the problems above would go away. Instead, we will have to add some CONFIG_SPL_* (and CONFIG_TPL_*) options such as CONFIG_SPL_DM, but we will not have much. Anyway, this is what we do now in scripts/Makefile.spl. I admit my mistake with my apology and this commit switches to the single .config configuration. It is not so difficult to do that: - Remove unnecessary processings from scripts/multiconfig.sh This file will remain for a while to support the current defconfig format. It will be removed after more cleanups are done. - Adjust some makefiles and Kconfigs - Add some entries to include/config_uncmd_spl.h and the new file scripts/Makefile.uncmd_spl. Some CONFIG options that are not supported on SPL must be disabled because one .config is shared between SPL and U-Boot proper going forward. I know this is not a beautiful solution and I think we can do better, but let's see how much we will have to describe them. - update doc/README.kconfig More cleaning up patches will follow this.

* kbuild: prepare for moving headers into mach-*/include/machMasahiro Yamada2015-02-21-4/+15
| | | | | | | | | | | | | | | | | | | | | In U-Boot, SoC-specific headers are placed in arch/$(ARCH)/include/asm/arch-$(SOC) and a symbolic link to that directory is created at the early stage of the build process. Creating and removing a symbolic link during the build is not preferred. In fact, Linux Kernel did away with include/asm-$(ARCH) directories a long time time ago. As for ARM, now it is possible to collect SoC sources into arch/arm/mach-$(SOC). It is also reasonable to move SoC headers into arch/arm/mach-$(SOC)/include/mach. This commit prepares for that. If the directory arch/$(ARCH)/mach-$(SOC)/include/mach exists, a symbolic to that directory is created. Otherwise, a symbolic link to arch/$(ARCH)/include/asm/arch-$(SOC) or arch-$(CPU) is created.
