2014-09-24cosmetic: replace MIN, MAX with min, maxMasahiro Yamada

2014-09-13kconfig: remove redundant "string" type in arch and board KconfigsMasahiro Yamada
Now the types of CONFIG_SYS_{ARCH, CPU, SOC, VENDOR, BOARD, CONFIG_NAME} are specified in arch/Kconfig. We can delete the ones in arch and board Kconfig files. This commit can be easily reproduced by the following command: find . -name Kconfig -a ! -path ./arch/Kconfig | xargs sed -i -e ' /config[[:space:]]SYS_\(ARCH\|CPU\|SOC\|\VENDOR\|BOARD\|CONFIG_NAME\)/ { N s/\n[[:space:]]*string// } ' Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>

2014-07-30kconfig: add board Kconfig and defconfig filesMasahiro Yamada
This commit adds: - arch/${ARCH}/Kconfig provide a menu to select target boards - board/${VENDOR}/${BOARD}/Kconfig or board/${BOARD}/Kconfig set CONFIG macros to the appropriate values for each board - configs/${TARGET_BOARD}_defconfig default setting of each board (This commit was automatically generated by a conversion script based on boards.cfg) In Linux Kernel, defconfig files are located under arch/${ARCH}/configs/ directory. It works in Linux Kernel since ARCH is always given from the command line for cross compile. But in U-Boot, ARCH is not given from the command line. Which means we cannot know ARCH until the board configuration is done. That is why all the "*_defconfig" files should be gathered into a single directory ./configs/.

2014-07-23stdio: Pass device pointer to stdio methodsSimon Glass
At present stdio device functions do not get any clue as to which stdio device is being acted on. Some implementations go to great lengths to work around this, such as defining a whole separate set of functions for each possible device. For driver model we need to associate a stdio_dev with a device. It doesn't seem possible to continue with this work-around approach. Instead, add a stdio_dev pointer to each of the stdio member functions. Note: The serial drivers have the same problem, but it is not strictly necessary to fix that to get driver model running. Also, if we convert serial over to driver model the problem will go away. Code size increases by 244 bytes for Thumb2 and 428 for PowerPC. 22: stdio: Pass device pointer to stdio methods arm: (for 2/2 boards) all +244.0 bss -4.0 text +248.0 powerpc: (for 1/1 boards) all +428.0 text +428.0 Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Marek Vasut <marex@denx.de> Reviewed-by: Marek Vasut <marex@denx.de>
2014-07-23stdio: Remove redundant code around stdio_register() callsSimon Glass
There is no point in setting a structure's memory to NULL when it has already been zeroed with memset(). Also, there is no need to create a stub function for stdio to call - if the function is NULL it will not be called. This is a clean-up, with no change in functionality.

2014-06-23x86: Enable 32-bit build using x86_64 multilib toolchainVasili Galka
Until now building the x86 arch boards required 32-bit toolchain. As many x86_64 toolchains come with 32-bit support (multilib) that's a good idea to enable build with such toolchains. The change required was to specify the usage of 32-bit explicitly to the compiler and the linker (-m32 and -m elf_i386 flags) and locate the right libgcc path.

2014-03-28kbuild: move asm-offsets.c from SoC directory to arch/$(ARCH)/libMasahiro Yamada
U-Boot has supported two kinds of asm-offsets.h. One is generic for all architectures and its source is located at ./lib/asm-offsets.c. The other is SoC specific and its source is under SoC directory. The problem here is that only boards with SoC directory can use the asm-offsets infrastructure. Putting asm-offsets.c right under CPU directory does not work. Now a new demand is coming. PowerPC folks want to use asm-offsets. But no PowerPC boards have SoC directory. It seems inconsistent that some boards add asm-offsets.c to SoC directoreis and some to CPU directories. It looks more reasonable to put asm-offsets.c under arch/$(ARCH)/lib. This commit merges asm-offsets.c under SoC directories into arch/$(ARCH)/lib/asm-offsets.c. By the way, I doubt the necessity of some entries in asm-offsets.c. I am leaving refactoring to the board maintainers. Please check "TODO" in the comment blocks in arch/{arm,nds32}/lib/asm-offsets.c.

2014-03-07kbuild: add CONFIG_ prefix to USE_PRIVATE_LIBGCCMasahiro Yamada
Before this commit, USE_PRIVATE_LIBGCC was defined in arch-specific config.mk and referenced in arch/$(ARCH)/lib/Makefile. We are not happy about parsing config.mk again and again. We have to keep the same behavior with a different way. By adding "CONFIG_" prefix, this macro appears in include/autoconf.mk, include/spl-autoconf.mk. (And treating USE_PRIVATE_LIBGCC as CONFIG macro is reasonable enough.) Tegra SoC family defined USE_PRIVATE_LIBGCC as "yes" in arch/arm/cpu/arm720t/tegra*/config.mk, whereas did not define it in arch/arm/cpu/armv7/tegra*/config.mk. It means Tegra enables PRIVATE_LIBGCC only for SPL. We can describe the same behavior by adding #ifdef CONFIG_SPL_BUILD # define CONFIG_USE_PRIVATE_LIBGCC #endif to include/configs/tegra-common.h.

2014-02-19dts: generate multiple device tree blobsMasahiro Yamada
It is convenient to have all device trees on the same SoC compiled. It allows for later easy repackaging without the need to re-run the make file. - Build device trees with the same SoC under arch/$(ARCH)/dts - Copy the one specified by CONFIG_DEFAULT_DEVICE_TREE or DEVICE_TREE=... to dts/dt.dtb Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
2014-02-19dts: move device tree sources to arch/$(ARCH)/dts/Masahiro Yamada
Unlike Linux Kernel, U-Boot historically had *.dts files under board/$(VENDOR)/dts/ and *.dtsi files under arch/$(ARCH)/dts/. I think arch/$(ARCH)/dts dicretory is a better location to store both *.dts and *.dtsi files. For example, before this commit, board/xilinx/dts directory had both Microblaze dts (microblaze-generic.dts) and ARM dts (zynq-*.dts), which are totally unrelated. This commit moves *.dts to arch/$(ARCH)/dts/ directories, allowing us to describe nicely mutiple DTBs generation in the next commit. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
2014-02-19dts: re-write dts/Makefile more simply with KbuildMasahiro Yamada
Useful rules in scripts/Makefile.lib allows us to easily generate a device tree blob and wrap it in assembly code. We do not need to parse a linker script to get output format and arch. This commit deletes ./u-boot.dtb since it is a copy of dts/dt.dtb. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
2014-02-19kbuild: change out-of-tree buildMasahiro Yamada
This commit changes the working directory where the build process occurs. Before this commit, build process occurred under the source tree for both in-tree and out-of-tree build. That's why we needed to add $(obj) prefix to all generated files in makefiles like follows: $(obj)u-boot.bin: $(obj)u-boot Here, $(obj) is empty for in-tree build, whereas it points to the output directory for out-of-tree build. And our old build system changes the current working directory with "make -C <sub-dir>" syntax when descending into the sub-directories. On the other hand, Kbuild uses a different idea to handle out-of-tree build and directory descending. The build process of Kbuild always occurs under the output tree. When "O=dir/to/store/output/files" is given, the build system changes the current working directory to that directory and restarts the make. Kbuild uses "make -f $(srctree)/scripts/Makefile.build obj=<sub-dir>" syntax for descending into sub-directories. (We can write it like "make $(obj)=<sub-dir>" with a shorthand.) This means the current working directory is always the top of the output directory. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Tested-by: Gerhard Sittig <gsi@denx.de>

2013-04-15x86: Fix DRAM bank size init with generic boardSimon Glass
The intention of the memory init code is that it should work the same with CONFIG_SYS_GENERIC_BOARD and without. This is tricky because dram_init() is called prior to relocation with generic board (matching other archs) and after relocation without generic board. Adjust the init sequence so that dram_init() is not called in the generic board case, which seems like the easiest fix for now. Also ensure that relocation addresses are still calculated.
