please do not change it you specify it at runtime btw: you can use arm-elf- toolchains and others to compile u-boot so why do you want to modify the default one? > endif > ifeq ($(ARCH),i386) > CROSS_COMPILE = i386-linux- > @@ -253,7 +253,7 @@ LIBBOARD = board/$(BOARDDIR)/lib$(BOARD) > LIBBOARD := $(addprefix $(obj),$(LIBBOARD)) > > # Add GCC lib > -PLATFORM_LIBS += -L $(shell dirname `$(CC) $(CFLAGS) > -print-libgcc-file-name`) -lgcc > +PLATFORM_LIBS += -L $(shell dirname `$(CC) $(CFLAGS) > -print-libgcc-file-name`) -lgcc -lgcc_eh > please do it in a fix commit > # The "tools" are needed early, so put this first > # Don't include stuff already done in $(LIBS) > @@ -2641,6 +2641,18 @@ SMN42_config : unconfig > @$(MKCONFIG) $(@:_config=) arm arm720t SMN42 siemens lpc2292 > > > ######################################################################### > +## ARM CORTEX Systems > +######################################################################### > +omap3_beagle_config : unconfig > + @$(MKCONFIG) $(@:_config=) arm omap3 beagle omap3 > + add it when you add each board (1 board => 1 patch) > +omap3_overo_config : unconfig > + @$(MKCONFIG) $(@:_config=) arm omap3 overo omap3 > + > +omap3_evm_config : unconfig > + @$(MKCONFIG) $(@:_config=) arm omap3 evm omap3 > + > +######################################################################### > ## XScale Systems > > ######################################################################### > > diff -uprN uboot_clean/cpu/omap3/config.mk > uboot_beagle/cpu/omap3/config.mk > --- uboot_clean/cpu/omap3/config.mk 1970-01-01 01:00:00.000000000 +0100 > +++ uboot_beagle/cpu/omap3/config.mk 2008-08-22 19:52:20.000000000 +0200 > @@ -0,0 +1,34 @@ > +# > +# (C) Copyright 2002 > +# Gary Jennejohn, DENX Software Engineering, <[EMAIL PROTECTED]> > +# > <cut GPL> > +# > +PLATFORM_RELFLAGS += -fno-strict-aliasing -fno-common -ffixed-r8 \ > + -msoft-float > + > +PLATFORM_CPPFLAGS += -march=armv7a Do you really need armv7a march?
