| * usb: spear: Add support for both SPEAr600 EHCI controllersStefan Roese2015-08-19-3/+41
| | | | | | | | | | | | | | | | | | | | | | USB EHCI on SPEAr600 has not been tested for a while. The base controller addresses are missing. This patch adds the defines to the header.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | zynq-7000.dtsi include skeleton.dtsi which contains memory node with base address and size zero. If you add memory@0 node to the platform DTS in final DTB there are two memory nodes and U-Boot works with the first one (with zeros) which end up in failing in dram_init because size is zero. Platform memory node should rewrite default memory node setup from skeleton.dtsi that's why platfroms needs to also use memory as node name instead of memory@0.

* of: clean up OF_CONTROL ifdef conditionalsMasahiro Yamada2015-08-18-99/+74
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* linux/kconfig.h: add CPP macros useful for per-image config optionsMasahiro Yamada2015-08-18-0/+74
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* i2c: lpc32xx: correct sanity check for requested bus speedVladimir Zapolskiy2015-08-18-11/+11
| | | | | | | | | | | | | | | | | | | | | | | | LPC32xx has 3 I2C bus controllers, 2 of them are used as generic ones and their parent clock is HCLK and CLK_HI/CLK_LO registers are 10 bit wide. This means that if HCLK is 104MHz, then minimal configurable I2C clock speed is about 51KHz. Only USB OTG I2C bus controller CLK registers are 8 bit wide, thus in assumption that peripheral clock is 13MHz it allows to set the minimal bus speed about 25.5KHz. Check for negative half clock value is removed since it is always false. The change fixes the following problem for I2C busses 0 and 1: => i2c dev 0 Setting bus to 0 => i2c speed 100000 Setting bus speed to 100000 Hz Failure changing bus speed (-22) Signed-off-by: Vladimir Zapolskiy <vz@mleia.com> Tested-by: Sylvain Lemieux <slemieux@tycoint.com>
