I found a good toolchain and gave building the series a whirl, and here's a few things that need fixing: - The davinci symlink isn't safe, running make again results in ln complaining. - The symlink doesn't work in conjunction with separate object directories as it is in the main src tree. - With O= we get arch/arm/cpu/arm926ejs/davinci/libdavinci.o because of the above, which makes link fail.

May be i must copy pinmux.c,reset.c,timer.c,cpu.c from arch/arm/arm926ejs/davinci to arch/c6x/c674x/c674x, remove from them all not used ifdef (#ifdef CONFIG_SOC_DM355) and don't set in boards.cfg SOC for board? This allow don't use symlink.

No, I think you just need to rework the mkconfig logic you're adding. It should be, roughly, outside of the ! -z ${soc} check: If c6x and davinci rm -f arch/c6x/cpu/c674x/davinci rm -f asm/arch if srctree != objtree set symlinks one way else set symlinks another way fi fi
Then once that works, see if you can shrink the logic down to just set a prefix variable or two and always set the symlinks.
