Package hierarchy is not reflected by directory hierarchy

[erlingrj]

The code is structured into two directories in the source folder: uart (which is not used) and Core. Then most of the source files are in a package called: flexpret.core. Which does not make sense. The package names should reflect the directory layout. There is no folder name core. Additionally, other files are just in the flexpret package. On top of this, some files are in the Core package.

Questions: Is it necessary to have all of these different packages cant we just have a single package flexpret?
