ARM: refactor compiler options in config.mk Every ARM cpu config.mk (arch/arm/cpu/{CPUDIR}/config.mk) defines: PLATFORM_RELFLAGS += -fno-common -ffixed-r8 -msoft-float So, this patch moves the common compiler options to arch/arm/config.mk.

* Update Intel IXP4xx support - Add IXP4xx NPE ethernet MAC support - Add support for Intel IXDPG425 board - Add support for Prodrive PDNB3 board - Add IRQ support Patch by Stefan Roese, 23 May 2006 [This patch does not include cpu/ixp/npe/IxNpeMicrocode.c which still sufferes from licensing issues.

IXP: Make IXP buildable with arm-linux- toolchains Add -EB flag to LD to switch endianness of the linker. This should make armeb targets buildable again. Also, make use of U-Boot's internal libgcc instead of toolchain's one, this works around the use of libraries from GCC, which might be little endian.

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%.
