Apart from having parameters from bootloaders available for RTEMS drivers 
this may also be a solution for many embedded systems to hold system wide 
parameters and distribute it to different modules and subsystems

I appreciate a "(configuration) parameter database", whatever technology it 
  will use as a standard component in RTEMS. We use a flat structure with 
ASCII names and simple data types like string, int, float since over 15 
years and there is a growing need for structured layout, i. e. hierachical 
namespace, aggregate types, like arrays and structures.

We would support efforts toward such a database, the APIs and the methods. 
The use is much wider than an interface between bootloaders and BSP/drivers.
