2014-11-11kconfig: zynq: Add ZYBO boardPeter Crosthwaite

2014-11-07cppcheck cleanup: fix nullPointer errorsWolfgang Denk
There are a number of places where U-Boot intentionally and legally accesses physical address 0x0000, for example when installing exception vectors on systems where these are located in low memory. Add "cppcheck-suppress nullPointer" comments to silence cppcheck where this is intentional and legal. Signed-off-by: Wolfgang Denk <wd@denx.de>
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>
2014-08-31zynq: kconfig: move board select menu and common settingsMasahiro Yamada
Becuase the board select menu in arch/arm/Kconfig is too big, move the Zynq board select menu to zynq/Kconfig. Consolidate also common settings (CONFIG_SYS_CPU="armv7" and CONFIG_SYS_SOC="zynq").

2014-08-08zynq: spl: Add vectors section to linker scriptPeter Crosthwaite
The vectors section contains the _start symbol which is used as the program entry point. Add it to the linker script in same fashion as done for regular u-boot. This allows for correct generation of an spl elf with a non-zero entry point. A similar change was applied to sunxi platform in "sunxi: Fix u-boot-spl.lds to refer to .vectors" (sha1: 9e5f80d823e3fd2a685b10ecf02009e34b86cff9) This also allows for placement of the vector table at the hivecs location by setting the TEXT_BASE to 0xffff0000.

2014-05-14zynq: treat ps7_init.c/h as external files to ignore themMasahiro Yamada
ps7_init.c and ps7_init.h are supposed to be exported by hw project and copied to board/xilinx/zynq/ directory. We want them to be ignored by git. So what we should do is to always treat them as external files rather than replacing ps7_init.c This commit does: - Move a weak function ps7_init() to arch/arm/cpu/armv7/zynq/spl.c and delete board/xilinx/zynq/ps7_init.c - Compile board/xilinx/zynq/ps7_init.c only when it exists - Add .gitignore to ignore ps7_init.c/h Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Signed-off-by: Michal Simek <michal.simek@xilinx.com>

Resolution consists in adjusting the list of object files in the main branch version. This also applies to two files which are not listed as conflicting but had to be modified: board/compulab/common/Makefile board/udoo/Makefile include/configs/omap4_common.h conflicts are due to the OMAP4 conversion to ti_armv7_common.h on the ARM side, and CONFIG_SYS_HZ removal on the main side. Resolution is to convert as this icludes removal of CONFIG_SYS_HZ. include/configs/pdnb3.h is due to a removal on ARM side. Trivial resolution is to remove the file. Note: 'git show' will also list two files just because they are new: include/configs/am335x_igep0033.h include/configs/omap3_igep00x0.h
