Remove redundant armv4 flag from arm926ejs compile flags Currently the arm926ejs tree has the armv4 option set during compilation. This flag does not belong here because a arm926 CPU is always a armv5 CPU. Signed-off-by: Remy Bohmer <linux@bohmer.net> 2008-12-05 06:25:57 +09:00			`PLATFORM_CPPFLAGS += -march=armv5te`
Make sure only supported compiler options are used Import "cc-option" shell function from kernel and use it to get the correct ARM GCC options for individual CPUs Patch by Peter Pearse, 30 Jun 2005 2005-10-05 05:38:24 +09:00			`# =========================================================================`

Reduce build times 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%.

imx: Fix automatic make targets for imx images 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 reference 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> 2013-02-11 13:33:51 +09:00			`ALL-y += $(obj)u-boot.imx`
