Maybe someone can port the Etherboot to powerpc. And it should be some easy.

Finally, someone has recognized the lack of support with LinuxBios. About 6 months ago we decide to do an x86 based project but abandoned it because of the lack of support for this bootloader. The code is disorganized and in disarray as far as I'm concerend. We were on a tight schedule and didn't have the luxury of spending a lot of time trying to understand the code layout. This was due in part to the lack of badly needed documentation and code organization. We decided to base our design on a powerpc and go with u-boot. Hopefully by the time we decide to do cost reduced version, LinuxBios will be usable for the masses and not just for an elite group of people who assume everybody else uses the x86 for everyday use.:-(

I think this is a reasonable idea, particularly your
suggestion of
making linuxbios more modular. One of my main beefs with
the payload
strategy is that each payload has to provide it's own set
of,
potentially buggy, driver code. If we have 5 payloads then
we have 5
sets of drivers that all do the same thing slightly
differently. If
the drivers were modular enough so that a payload could call
them
directly, then this would go a long way to addressing these concerns.
As far as I can tell the only drivers involved would be
output drivers,
ie. video output and serial output. There the extensible
LinuxBIOS
table could come into play. The video driver could store a pointer
to the
framebuffer, the resolution and maybe even a font, to save
duplicates.
Serial is only a kilobyte or so of a driver i think.
Have I forgotten something?
PCI device code and resource information should be available for payloads to use. A payload should not have to re-probe for devices on the PCI bus.
