Greetings,

System is mcf5272 on  Arcturus uCdimm/uCevolution development board
Requirement is  to receive data from external board connected via
gpio.

My general question due to ignorance
Are there any code samples I could look at?  I tried
adding in parallel port support in the kernel but it
doesn't compile which is no surprise.

Should the plan be to write a driver such as /dev/gpio or
just access the gpio addresses directly?  The latter might
be easier, perhaps?
