* dm: Don't attach the device tree to SPL with of-platdataSimon Glass2016-07-141-1/+1
| | | | | | | | When of-platdata is used in SPL we don't use the device tree. So there is no point in attaching it. Adjust the Makefile to skip attaching the device tree when of-platdata is enabled. Signed-off-by: Simon Glass <sjg@chromium.org>

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.

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/ ...

* Makefile: Add target for building bootable SPL image for SoCFPGAMarek Vasut2015-08-081-0/+10
| | | | | | | | | | | | Add build target for generating boot partition images recognised by the SoCFPGA BootROM. The SoCFPGA BootROM expects four copies of the u-boot-spl-dtb.sfp at the beginning of boot partition. Those are u-boot-spl-dtb.bin augmented by a header with which the BootROM can work. The u-boot-dtb.img uImage is appended to this to produce a full boot partition image, the u-boot-with-spl-dtb.sfp . This is the name of the final target. Signed-off-by: Marek Vasut <marex@denx.de>
* driver/ddr/altera: Add DDR driver for Altera's SDRAM controllerDinh Nguyen2015-08-081-0/+1
| | | | | | | | This patch enables the SDRAM controller that is used on Altera's SoCFPGA family. This patch configures the SDRAM controller based on a configuration file that is generated from the Quartus tool, sdram_config.h. Signed-off-by: Dinh Nguyen <dinguyen@opensource.altera.com>

* kbuild: create symbolic link only for ARM, AVR32, SPARC, PowerPC, x86Masahiro Yamada2015-07-271-0/+2
| | | | | | | | | | | | | The symbolic link to SoC/CPU specific header directory is created during the build, while it is only necessary for ARM, AVR32, SPARC, x86, and some CPUs of PowerPC. For the other architectures, it just results in a broken symbolic link. Introduce CONFIG_CREATE_ARCH_SYMLINK to not create unneeded symbolic links.
