Add support for the tracing infastructure in coreboot. The compiler is forced to emmit special functions on every entry/exit of the function. Add a compile time option to support it. Function entries will be printed in the console. The CONFIG_TRACE has more documentation. Patch for userspace tools will follow.

src/lib/trace.c: Make address size generic On platforms that didn't use 32-bit addresses, enabling the CONFIG_TRACE option (Trace function calls) would break the build due to a cast from a pointer of a different size. This fixes this warning: src/lib/trace.c:29:58: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast] Change-Id: Iaab13c1891b6af7559ea6982ecc6e74c09dd0395 Signed-off-by: Martin Roth <martinroth@google.com> Reviewed-on: https://review.coreboot.org/13962 Tested-by: build bot (Jenkins) Reviewed-by: Stefan Reinauer <stefan.reinauer@coreboot.org> Reviewed-by: Paul Menzel <paulepanter@users.sourceforge.net>
