CROSS_COMPILE is generally passed from the command line or by the environment variable because cross tools vary from user to user.
But, having some choices of often used CROSS_COMPILE seems reasonable. $(call cc-cross-prefix, ...) returns the first prefix where a prefix$(CC) is found in PATH. If your cross tools exist in the argument of $(call cc-cross-prefix, ...), you do not have to specify it explicitly. Signed-off-by: Masahiro Yamada <yamad...@jp.panasonic.com> --- My question is which cross tools are popular enough to be added to the list. In my opition, arm-linux-gnueabi-gcc is popular because it is distributed in Ubuntu. On the other hand, I am not sure ppc_8xx-gcc is currently being used. Which one should be to added/deleted to our default list. Your comments are very welcome.
