[En-Nut-Discussion] Change in directory structure for platform dependend files

[Ole Reinhardt]

Hi Oliver,

I also struggled with this some time ago.

I realy agree we should move the files as proposed!

What's about the dev directory? Here we also have a lot of plattform 
dependand code. Should we perhpas also move the plattform dependand 
files in the special directory and only leave plattform independand 
drivers in the main dev directory?

And if we just started thinking about portability... I like to start a 
discussion about better portability of the driver model at all... For a 
long time I just thought about a driver model a bit more like the linux 
driver model. With drivers devided into character driver (Serial, LCD, 
TWI...), block devices (flash, harddisk), network drivers (ethernet, 
perhaps also can), filesystems (fat, urom) and misc drivers (PIO...)

Any suggestions? This would be a lot of work, but perhpas a good goal 
for NutOS 5.0

Regards,

Ole
