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.
