The axis devs responded with the solution that does not rely on the CONFIG_ETRAX_ARCH_Vxx but instead includes arch-v10 and arch-v32 dirs in header-y target. I guess it is OK to do so, since we might need headers for v10 and/or v32 CPUs. The only catch would be to make correct symlink to the desired arch-vxx directory. diff --git a/include/asm-cris/Kbuild b/include/asm-cris/Kbuild index 1745545..d5b6319 100644 --- a/include/asm-cris/Kbuild +++ b/include/asm-cris/Kbuild @@ -1,7 +1,7 @@ include include/asm-generic/Kbuild.asm -header-$(CONFIG_ETRAX_ARCH_V10) += arch-v10/ -header-$(CONFIG_ETRAX_ARCH_V32) += arch-v32/ +header-y += arch-v10/ +header-y += arch-v32/ header-y += ethernet.h header-y += rtc.h I think it is the correct path to take, but will still try to work out the best solution with the Axis devs later on..
