The ugly "setup.c" file


Our current setup.c is as ugly as vendor ones
It refers to several other drivers (timer, uart, pll, ...)

It must be augmented any time a new driver is added

Worse, such additions may depend on what we configure
Worse, it may need to depend on what main() does


What we really need, is a simpler approach
The init function should be part of the driver
If the driver is not built, its initialization would not be built either
If the driver is not used, its initialization should  not be run
