* cppcheck cleanup: fix nullPointer errorsWolfgang Denk2014-11-07-1/+4
| | | | | | | | | | | 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>
* ppc: Fix ppc4xx CONFIG_SYS_GENERIC_BOARDDirk Eibach2014-11-05-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I realized that with v2014.10 u-boot is not starting up on ppc4xx boards with CONFIG_SYS_GENERIC_BOARD set.

Every mpc8xx board has its own linker script under the board directory, resulting in lots of duplication of linker scripts. I notice eight mpc8xx boards have the same linker script.

Going forward, we use Kconfig for the board configuration. mkconfig will never be used. Nor will include/config.mk be generated. Kconfig must be adjusted for U-Boot because our situation is a little more complicated than Linux Kernel. We have to generate multiple boot images (Normal, SPL, TPL) from one source tree. Each image needs its own configuration input. Usage: Run "make <board>_defconfig" to do the board configuration. It will create the .config file and additionally spl/.config, tpl/.config if SPL, TPL is enabled, respectively. You can use "make config", "make menuconfig" etc. to create a new .config or modify the existing one. Use "make spl/config", "make spl/menuconfig" etc. for spl/.config and do likewise for tpl/.config file. The generic syntax of configuration targets for SPL, TPL is: <target_image>/<config_command> Here, <target_image> is either 'spl' or 'tpl' <config_command> is 'config', 'menuconfig', 'xconfig', etc. When the configuration is done, run "make". (Or "make <board>_defconfig all" will do the configuration and build in one time.) For futher information of how Kconfig works in U-Boot, please read the comment block of scripts/multiconfig.py. By the way, there is another item worth remarking here: coexistence of Kconfig and board herder files. Prior to Kconfig, we used C headers to define a set of configs. We expect a very long term to migrate from C headers to Kconfig. Two different infractructure must coexist in the interim. In our former configuration scheme, include/autoconf.mk was generated for use in makefiles. It is still generated under include/, spl/include/, tpl/include/ directory for the Normal, SPL, TPL image, respectively.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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/.
