How about a few symlinks.....

How about a few symlinks.....

[Dan Malek]

While editing some Makefiles I was wondering what people thought
of using symlinks to processor dependent files instead of nested
ifdefs in Makefiles?

For starters, make arch/ppc/kernel/head.S a symlink to the appropriate
one in that directory, and derive the name to use from one of the
config options.  I thought I would ask before demonstrating the change.

Thanks.

I like the general concept.  I was suggesting the general idea for header
files to Tom Rini recently since I really like how clean it makes things
in include/asm-arm where there are include/asm-arm/arch-???? directories.
Although their overall software architecture is different and we'd need
some changes, I think it's a great cleanup goal.

Also, include/asm is just a lymlink to asm-${arch}.

Yes, and ARM goes and makes a few other config-dependant symlinks.  So
there's precidence (and it'd be easy to setup too, more or less).
