* imx: Fix automatic make targets for imx imagesBenoît Thébaudeau2013-04-12-2/+6
| | | | | | | | | | | | | | Automatically build the 'u-boot.imx' (i.e. imx header + u-boot.bin) and 'SPL' (i.e. imx header + u-boot-spl.bin) make targets for all imx processors supporting this header, so for arm926ejs, arm1136 and armv7. Some combinations were missing. At the same time, fix the build of SPL targets not supporting the imx header on arm1136. For arm1136, the 'SPL' make target was forced to build in all cases if CONFIG_SPL_BUILD was defined, even for non-imx platforms or imx setups without an imx header.

* build: imx: Fix 'u-boot.imx' build without full OBJTREE referenceOtavio Salvador2013-02-12-1/+1
| | | | | | | | | | | | | | | | | | | When calling 'make u-boot.imx' the build were failing as it were expecting the full path for the file; this regression has been included by commit 71a988a (imximage.cfg: run files through C preprocessor). The direct references for u-boot.imx were replaced by $(obj) as config.mk handles the proper setting of it making it set to $(OBJTREE) when required. The build has been test using: - ./MAKEALL -s mx5 -s mx6 - make u-boot.imx - make O=/tmp/build Signed-off-by: Otavio Salvador <otavio@ossystems.com.br>
* imximage.cfg: run files through C preprocessorTroy Kisky2013-01-22-1/+1
| | | | | | | | | | | | The '#' used as comments in the files cause the preprocessor trouble, so change to /* */. The mkimage command which uses this preprocessor output was moved to arch/arm/imx-common/Makefile .gitignore was updated to ignore .cfgtmp files.

* Reduce build timesWolfgang Denk2011-11-03-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | U-Boot Makefiles contain a number of tests for compiler features etc. which so far are executed again and again. On some architectures (especially ARM) this results in a large number of calls to gcc. This patch makes sure to run such tests only once, thus largely reducing the number of "execve" system calls. Example: number of "execve" system calls for building the "P2020DS" (Power Architecture) and "qong" (ARM) boards, measured as: -> strace -f -e trace=execve -o /tmp/foo ./MAKEALL <board> -> grep execve /tmp/foo | wc -l Before: After: Reduction: ================================== P2020DS 20555 15205 -26% qong 31692 14490 -54% As a result, built times are significantly reduced, typically by 30...50%.
