* mmc: exynos dwmmc: check boot mode before init dwmmcPrzemyslaw Marczak2015-02-23-1/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before this commit, the mmc devices were always registered in the same order. So dwmmc channel 0 was registered as mmc 0, channel 1 as mmc 1, etc. In case of possibility to boot from more then one device, the CONFIG_SYS_MMC_ENV_DEV should always point to right mmc device. This can be achieved by init boot device as first, so it will be always registered as mmc 0. Thanks to this, the 'saveenv' command will work fine for all mmc boot devices. Exynos based boards usually uses mmc host channels configuration: - 0, or 0+1 for 8 bit - as a default boot device (usually eMMC) - 2 for 4bit - as an optional boot device (usually SD card slot) And usually the boot order is defined by OM pin configuration, which can be changed in a few ways, eg. - Odroid U3 - eMMC card insertion -> first boot from eMMC - Odroid X2/XU3 - boot priority jumper By this commit, Exynos dwmmc driver will check the OM pin configuration, and then try to init the boot device and register it as mmc 0.

* 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.

This structure did not fit very well in some cases. [1] AT91 AT91 SoC family have been developed across some ARM processor generations. Generally speaking, some IPs are often re-used in the same SoC family (same SoC vendor) even when the main processor is updated. As a result, a SoC-common directory is needed in the upper level. Currently, AT91 source files are placed as follows: arch/arm/cpu/arm920t/at91/* arch/arm/cpu/arm926ejs/at91/* arch/arm/cpu/armv7/at91/* arch/arm/cpu/at91-common/* Once directories are split, the motivation for refactorings across CPU directories is lost. Some files in arm920t/at91/ and arm926ejs/at91/ are so similar that they could be merged. [2] Tegra Tegra is a little bit special case where different CPUs are used for SPL and the main U-boot. To obey the arch/$(ARCH)/cpu/$(CPU)/$(SOC) structure, the source files must be placed across the CPUs, again SoC-common directory is necessary in the upper level. Moreover, there are several families in Tegra: Tegra20, Tegra30, Tegra114, Tegra124. Here again, the tegra-common directory is needed to contain commonly-used files. Tegra directories have been sprinkled in the directory structure. arch/arm/cpu/arm720t/tegra20 arch/arm/cpu/arm720t/tegra30 arch/arm/cpu/arm720t/tegra114 arch/arm/cpu/arm720t/tegra124 arch/arm/cpu/arm720t/tegra-common arch/arm/cpu/armv7/tegra20 arch/arm/cpu/armv7/tegra30 arch/arm/cpu/armv7/tegra114 arch/arm/cpu/armv7/tegra124 arch/arm/cpu/armv7/tegra-common arch/arm/cpu/tegra20-common arch/arm/cpu/tegra30-common arch/arm/cpu/tegra114-common arch/arm/cpu/tegra124-common arch/arm/cpu/tegra-common As you see, splitting SoC code by the CPU is not going well, especially for ARM. Why don't we collect SoC-specific files into a single place? A good example we can follow is Linux's arch/arm/mach-* structure. This item was discussed in the following thread: http://thread.gmane.org/gmane.comp.boot-loaders.u-boot/188548/ Looks like I got some positive responses and we are almost ready to start this movement. This commit prepares arch/arm/Makefile for describing machdirs in it. After this commit, we can move SoC directory to arch/arm/mach-$(SOC) in simple steps although some cases such as AT91 and Tegra need more fixes. What we generally have to do is: [1] Move files arch/arm/cpu/$(CPU)/$(SOC)/* to arch/arm/mach-$(SOC)/* [2] Add machine entry into arch/arm/Makefile [3] Remove "obj-y += $(SOC)" from arch/arm/cpu/$(CPU)/Makefile [4] Fix the Kconfig file path in arch/arm/Kconfig [5] Modify MAINTAINERS if necessary Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>

Also, consolidate "config SYS_SOC" in each board Kconfig.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This came up in a discussion on the mailing list here: https://patchwork.ozlabs.org/patch/384613/ My concerns at the time were: - it doesn't need to be written in assembler - it doesn't need to be ARM-specific This patch provides a possible alternative. It works by allowing any serial driver to export one init function and provide a putc() function. These can be used to output debug data before the real serial driver is available. This implementation does not depend on driver model, and it is possible for it to operate without a stack on some architectures (e.g. PowerPC, ARM). It provides the same features as the ARM-specific debug.S but with more UART and architecture support. Signed-off-by: Simon Glass <sjg@chromium.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I2C chips do exist that require a write of some multi-byte data to occur in a single bus transaction (aka atomic transfer), otherwise either the write does not come into effect at all, or normal operation of internal circuitry cannot be guaranteed. The current implementation of the 'i2c write' command (transfer of multiple bytes from a memory buffer) in fact performs a separate transaction for each byte to be written and thus cannot support such types of I2C slave devices. This patch provides an alternative by allowing 'i2c write' to execute the write transfer of the given number of bytes in a single bus transaction if the '-s' option is specified as a final command argument. Else the current re-addressing method is used. Signed-off-by: Lubomir Popov <l-popov@ti.com> hs: adapt to CONFIG_DM_I2C
