Kbuild: introduce Makefile in arch/$ARCH/

2014-12-08T14:35:45Z

Introduce a Makefile under arch/$ARCH/ and include it in the top Makefile (similar to Linux kernel). This allows further refactoringi like moving architecture-specific code out of global makefiles, deprecating config variables (CPU, CPUDIR, SOC) or deprecating arch/$ARCH/config.mk. In contrary to Linux kernel, U-Boot defines the ARCH variable by Kconfig, thus the arch Makefile can only included conditionally after the top config.mk.

kbuild: use SoC-specific CONFIG to descend into SoC directory

2014-11-23T11:49:02Z

Use "obj-$(CONFIG_FOO) += foo/" where it is possible. Signed-off-by: Masahiro Yamada

kbuild: Descend into SOC directory from CPU directory

2014-11-23T11:49:02Z

Some CPUs of some architectures have SOC directories. At present, the build system directly descends into SOC directories from the top Makefile, but it should generally descend into each directory from its parent directory. Signed-off-by: Masahiro Yamada

kconfig: remove redundant "string" type in arch and board Kconfigs

2014-09-13T20:43:55Z

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

kconfig: delete redundant CONFIG_${ARCH} definition

kconfig: add board Kconfig and defconfig files

2014-07-30T12:48:01Z

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/.

bd_info: remove bi_barudrate member from struct bd_info

2014-05-12T19:19:45Z

gd->bd->bi_baudrate is a copy of gd->baudrate. Since baudrate is a common feature for all architectures, keep gd->baudrate only. It is true that bi_baudrate was passed to the kernel in that structure but it was a long time ago.

kbuild: move asm-offsets.c from SoC directory to arch/$(ARCH)/lib

2014-03-28T19:06:29Z

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. Signed-off-by: Masahiro Yamada Cc: Yuantian Tang

config.mk: specify the exact path to standalone linker script

2014-03-07T15:59:06Z

We want to change the build system to include config.mk only from ./Makefile and spl/Makefile. We must prepare for that in this commit. $(src) is a moving target and not handy for our purpose. We must replace it with a fixed path. Signed-off-by: Masahiro Yamada

kbuild: fix CROSS_COMPILE settings in config.mk

2014-03-04T17:15:30Z

The syntax CROSS_COMIPLE ?= does not work because config.mk is parsed after exporting CROSS_COMPILE. Like Linux Kernel's arch/$(ARCH)/Makefile, we must write as follows: ifeq ($(CROSS_COMPILE),) CROSS_COMPILE := endif Signed-off-by: Masahiro Yamada
