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.

sparc: merge CONFIG_SYS_CPU and CONFIG_SYS_VENDOR defines

2014-11-04T20:01:38Z

For now, all the SPARC boards in U-Boot are provided by Gaisler. Signed-off-by: Masahiro Yamada Cc: Daniel Hellstrom

sparc: merge arch/sparc/cpu/*/config.mk to arch/sparc/config.mk

2014-11-04T20:01:32Z

Remove arch/sparc/cpu/{leon2,leon3}/config.mk and move duplicated defines of -fPIC to arch/sparc/config.mk. Signed-off-by: Masahiro Yamada Cc: Daniel Hellstrom

sparc: Use nicer prompt for board select menu

2014-11-04T20:01:18Z

The Board names in the board select menu were simply taken from the board directory name by a conversion tool when switching to Kconfig. Let's use more descriptive prompts taken from include/configs/gr*.h and board/gaisler/*/config.mk. Signed-off-by: Masahiro Yamada Cc: Daniel Hellstrom

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/.

sparc: merge LEON2 and LEON3 linker scripts

2014-07-22T11:44:24Z

There is only one line diff between LEON2 and LEON3 linker scripts: - arch/sparc/cpu/leon2/start.o (.text) + arch/sparc/cpu/leon3/start.o (.text) They can be written in the same way: */start.o (.text) So, board/gaisler/grsim_leon2/u-boot.lds and arch/sparc/cpu/leon3/u-boot.lds can be merged into arch/sparc/cpu/u-boot.lds.

sparc: merge LEON3 linker scripts

2014-07-22T11:44:24Z

The linker scripts of LEON3 - board/gaisler/grsim/u-boot.lds - board/gaisler/gr_cpci_ax2000/u-boot.lds - board/gaisler/gr_ep2s60/u-boot.lds - board/gaisler/gr_xc3s_1500/u-boot.lds are the same (except cosmetic differences such as indentation). This commit merges them into arch/sparc/cpu/leon3/u-boot.lds. Signed-off-by: Masahiro Yamada Cc: Daniel Hellstrom
