While I can understand your position, let me explain that the idea
behind the API was to provide calls to really elementary operations
and printf() wasn't considered as such (we only have print, get and
test a single character as far as console ops go); things like pre-
formatting should be done in the application...
The demo application is just a demo, it links in the same printf-
formatting code that U-Boot library uses, but specific standalone
applications are supposed to implement their own formatting routines.
