Unify assembler function handling Instead of adding regparm(0) to each assembler function called by coreboot, add an asmlinkage macro (like the Linux kernel does) that can be different per architecture (and that is empty on ARM right now) Change-Id: I7ad10c463f6c552f1201f77ae24ed354ac48e2d9 Signed-off-by: Stefan Reinauer <reinauer@google.com> Reviewed-on: http://review.coreboot.org/1973 Reviewed-by: David Hendricks <dhendrix@chromium.org> Tested-by: build bot (Jenkins) Reviewed-by: Ronald G.

/* GCC's libgcc handling is quite broken. While the libgcc functions
* are always regparm(0) the code that calls them uses whatever the
* compiler call specifies. Therefore we need a wrapper around those
* functions. See gcc bug PR41055 for more information.
