Well, IMHO this code needs more than just a few little changes :-(

Thanks for that.

It is helpful to me. I will  try  to  merge  all  patches  that  I've
collected so far.

Yepp, Raphael has no time to care about this. I  met  him  yesterday,
and  we  agreed  to shift responsibilities. I received a message from
him today, that he assigned me and Magnus Damm (?) as  administrators
for the sourceforge tree.

That's correct, Raphael, isn't it?

I will try to coordinate changes a bit, and maybe start a re-write of
some parts of the code. I might have an engineer working on  this  by
mid-July to pick up what we have by then. My current intentions are:

* Make 8xxrom run on the TQM8xxL modules (99% of that are done)
* Add network boot using TFTP / BOOTP (Duncan Palmer is working on
  that, too)
* Add booting from PCMCIA / directly attached ATA disks (not working
  yet on the TQM8xxL)
* Add FLASH driver so that you can use the monitor to load an image
  over the network and write it to FLASH;
* Add some features needed for safe field upgradability (automatic
  selection between two or more boot images)

The list represents more or less the priorities as I see them at  the

Comments welcome, volunteers even more :-)
