Following changes have been introduced to ld in binutils-2.16: * Added SORT_BY_NAME and SORT_BY_ALIGNMENT to the linker script language to permit sorting sections by section name or section maximum alignment. http://sourceware.org/cgi-bin/cvsweb.cgi/~checkout~/src/ld/NEWS?rev=1.116&content-type=text/plain&cvsroot=src&only_with_tag=binutils-binutils-2_21 These new macros are used in mips.lds and all u-boot.lds files. I get follogwing error with ELDK-3.1.1 or other gcc-3.x based toolchains (IncaIP used as sample config): mips_4KC-ld -g -Ttext 0x80200000 -T mips.lds \ -o <snip>/u-boot-git//build/incaip/examples/standalone/hello_world -e hello_world <snip>/u-boot-git//build/incaip/examples/standalone/hello_world.o <snip>/u-boot-git//build/incaip/examples/standalone/libstubs.o \ -L<snip>/eldk-3.11/usr/bin/../lib/gcc-lib/mips-linux/3.3.3 -lgcc mips_4KC-ld:mips.lds:37: parse error This error refers to following line: .rodata : { *(SORT_BY_ALIGNMENT(SORT_BY_NAME(.rodata*))) } Following commit introduced that change for all u-boot.lds files: http://git.denx.de/?p=u-boot.git;a=commit;h=f62fb99941c625605aa16a0097b396a5c16d2c88 I'd claim that all toolchains with binutils lesser than 2.16 are not working anymore. > >> Thus ELDK-3.1.1 and earlier are not functional with mainline U-Boot >> anyway.

I have prepared a v3 of this patch that checks whether -mips32r2 is supported. If not than -mips32 will be used as fallback. But I want to clarify this first before I send it.
