Sorry, my fault - when saying that I was writing a HAL I
actually meant that I want to build upon an existing one,
extending it to support additional hardware. I intend to
use plf_if_init() to get my things initialized. Is this a
sensible approach?
The problem with the COMMS table is that the HAL I want to
build upon defines CYGNUM_HAL_VIRTUAL_VECTOR_NUM_CHANNELS
as a computed property with a fixed value, so in order to
extend the COMMS table I have to resort to
CYGNUM_HAL_VIRTUAL_VECTOR_AUX_CHANNELS, or don't I?
