2017-04-14board: sama5d3_xplained: Enable early debug UARTWenyou Yang
Enable the early debug UART to debug problems when an ICE or other debug mechanism is not available. Signed-off-by: Wenyou Yang <wenyou.yang@atmel.com>
2017-04-14board: sama5d3_xplained: Clean up codeWenyou Yang
Due to the introduction of the pinctrl and clk driver, and using device tree files, remove the unneeded hardcoded pin configuration and clock enabling code from the board file. Signed-off-by: Wenyou Yang <wenyou.yang@atmel.com>
2017-04-14board: sama5d3_xplained: Update to support DM/DTWenyou Yang
Update the configuration files to support the device tree and driver model, so do SPL. The device clock and pins configuration are handled by the clock and the pinctrl drivers respectively.

2016-02-18board: atmel: clean up the PMC_PLLICPR init codeWenyou Yang
Due to introducing the PMC_PLLICPR init function, use this function to clean up the code. Signed-off-by: Wenyou Yang <wenyou.yang@atmel.com> Tested-by: Heiko Schocher <hs@denx.de> Reviewed-by: Andreas Bießmann <andreas.devel@googlemail.com>
2016-02-18board: atmel: clean up peripheral clock codeWenyou Yang
Due to introducing the new peripheral clock handle functions, use these functions to reduce duplicated code.

2016-02-02arm: at91/spl: mpddrc: add struct atmel_mpddrc_configWenyou Yang
Add struct atmel_mpddrc_config to accommodate the mpddrc register configurations, not using the mpddrc register map structure, struct atmel_mpddrc, in order to increase readability and reduce run-time memory use.

2015-08-21arm: at91: pmc: replace the constant with a define in at91_pmc.hErik van Luijk
To enable the clocks on the at91 boards a constant (0x4) is used. This is replaced with a define in at91_pmc.h (1 << 2). Signed-off-by: Erik van Luijk <evanluijk@interact.nl> Reviewed-by: Andreas Bießmann <andreas.devel@googlemail.com>
2015-08-21arm: at91: mpddr: allow multiple DDR controllersErik van Luijk
The mpddr.c depends on ATMEL_BASE_MPDDRC for the base address to configure the controller. This cannot be used when there is more than one controller (i.e. AT91SAM9G45, AT91SAM9M10).

2015-02-21ARM: at91: move board select menu and common settingsMasahiro Yamada
The board select menu in arch/arm/Kconfig is still big. To slim down it, this commit moves AT91 boards to arch/arm/mach-at91/Kconfig. Also, consolidate "config SYS_SOC" in each board Kconfig. The Kconfig files under board/ directory were modified with the following command: find board -name Kconfig | xargs sed -i -e ' /config SYS_SOC/ { N /default "at91"/ { N d } } ' Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Acked-by: Andreas Bießmann <andreas.devel@googlemail.co>
2014-10-29kconfig: arm: introduce symbol for ARM CPUsGeorges Savoundararadj
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.

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>
2014-07-30Add board MAINTAINERS filesMasahiro Yamada
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.

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/.
