I guess the better approach is to have a thorough look at the linux
kernel drivers and their infrastructure. PTXdist is meant for building
an embedded _linux_ system, where linux means you have an os kernel that
handles this stuff for you and provides an abstract, stable interface to it.
For example taking the UARTs:
they get provided as /dev/tty* nodes. You just use them like any other
file, no need to do some initialization/control stuff like in the
embedded market (where you obviously come from).
The already existing device drivers will probably make up ~99.5% of all
your hardware handling code, and for the rest there's things like UIO,
for example.
But it's really essential to get your head around the OS kernel thing
and stop thinking embedded.
