If you are going to flatten the structure then you should also probably
correct the companion chip name. The code base this was started from
was vx800 but its been modified for the vx855. At the time OLPC got the
code the mods were already made so we don't know exactly what what
changed from vx800 to vx855.
The vx855 is a subset of the vx800. The code will probably work on a
vx800 but I'm sure there are subtle differences. Perhaps you should
rename it to be vx8xx and then start dealing with the differences when
you find them.
In other news... we have our Gen 1.5 hardware booting (OpenFirmware) and
Linux. Most stuff seems to work but its still in testing.
The bad news is that the vx8xx code won't work on the gen 1.5 ATest
board as written. We ended up having to use different RAM chips and so
there is not an SPD on the ATest. Also there are various things
different in the RAM subsystems between the vx555 demo board we had and
the gen 1.5 Atest. The code has various bits of hardcoded things for
the demo board.
The good news is that all of these settings are in the OpenFirmware
repository. So you can go get the proper settings.
Is there any sort of facility in the config files for a SPDless board?
Bari: Sorry I've not yet responded to your graphics email.. I'll try to
scratch out some time tonight to respond with whats going on in graphics.
