[Open-graphics] VGA text mode C version

[Timothy Normand Miller]

I'd like to work in integrating HQ today or tomorrow.  Do we have a
summary somewhere of the ports and how we're going to handle address,
byte enables, target, count, etc?

I'm going to start with the fifos.  To begin with, it'll just be those
in a module, wired for bypass only, and then we can insert HQ into
there next.

Here's what we have:

pci command/write fifo -> HQ -> bridge command fifo
bridge read data fifo -> HQ -> pci read data fifo

Am I missing anything?

I need to go look up the ports.


We have ports defined for a single out-standing read.  That won't work
for a block of reads, though.  Do we need it for anything?



There are other comments I've made about stuff I'm going to forget.
For instance, we need to make sure that timeouts work right.  I'm
going to go through the discussions, but I could use some help with
those details.
