* kconfig: arm: introduce symbol for ARM CPUsGeorges Savoundararadj2014-10-29-3/+0
| | | | | | | | | | | | | | | | | This commit introduces a Kconfig symbol for each ARM CPU: CPU_ARM720T, CPU_ARM920T, CPU_ARM926EJS, CPU_ARM946ES, CPU_ARM1136, CPU_ARM1176, CPU_V7, CPU_PXA, CPU_SA1100. Also, it adds the CPU feature Kconfig symbol HAS_VBAR which is selected for CPU_ARM1176 and CPU_V7. For each target, the corresponding CPU is selected and the definition of SYS_CPU in the corresponding Kconfig file is removed. Also, it removes redundant "string" type in some Kconfig files.

* kconfig: remove redundant "string" type in arch and board KconfigsMasahiro Yamada2014-09-13-5/+0
| | | | | | | | | | | | | | | | | | 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>
* Add board MAINTAINERS filesMasahiro Yamada2014-07-30-0/+6
| | | | | | | | | | | | | | | | | | | | We have switched to Kconfig and the boards.cfg file is going to be removed. We have to retrieve the board status and maintainers information from it. The MAINTAINERS format as in Linux Kernel would be nice because we can crib the scripts/get_maintainer.pl script. After some discussion, we chose to put a MAINTAINERS file under each board directory, not the top-level one because we want to collect relevant information for a board into a single place. TODO: Modify get_maintainer.pl to scan multiple MAINTAINERS files.

* kconfig: add board Kconfig and defconfig filesMasahiro Yamada2014-07-30-0/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | 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/.

* spl: consolidate arch/arm/include/asm/arch-*/spl.hMasahiro Yamada2014-06-06-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | arch/arm/include/asm/spl.h requires all SoCs to have arch/arm/include/asm/arch-*/spl.h. But many of them just define BOOT_DEVICE_* macros. Those macros are used in the "switch (boot_device) { ... }" statement in common/spl/spl.c. So they should not be archtecture specific, but be described as a simpile enumeration. This commit merges most of arch/arm/include/asm/arch-*/spl.h into arch/arm/include/asm/spl.h. With a little more effort, arch-zynq/spl.h and arch-socfpga/spl.h will be merged, while I am not sure about OMAP and Exynos.

* arm: mx5: Avoid hardcoding memory sizes on M53EVKMarek Vasut2014-03-31-7/+24
| | | | | | | | | | | | | | | | | | | The DRAM size can be easily detected at runtime on i.MX53. Implement such detection on M53EVK and adjust the rest of the macros accordingly to use the detected values. An important thing to note here is that we had to override the function for trimming the effective DRAM address, get_effective_memsize(). That is because the function uses CONFIG_MAX_MEM_MAPPED as the upper bound of the available DRAM and we don't have gd->bd->bi_dram[0].size set up at the time the function is called, thus we cannot put this into the macro CONFIG_MAX_MEM_MAPPED . Instead, we use custom override where we use the size of the first DRAM block which we just detected.
