Hello,
I've successfully ported U-Boot to the Motorola PrPMC800. Support for
FLASH, PCI, IDE and networking have bee successfully enabled. It has been
in use now for several weeks in a stable form. I do have one lingering
problem of not being able to turn on the L1 and L2 data caches. Doing so
apparently causes the system to hang. Unfortunately I don't have a BDI2000
setup for this board to better debug the problem. I used just a good ol'
console and plenty of printf statements to do the port.
I can't give a specific time for when I will have the port submitted for a
future release of U-Boot. But I will do it. I'd like to fix my cache
problem first and I have to finish the rest of the project for which U-Boot
is just one part. And that may be awhile.
Regards,
Mark.

AM Subject: PrPMC800 Port and Newbie Intro
Hello,
My name is Mark Lightfoot and I'm a software engineer with SITA INC. I'm
investing the possibility of porting U-Boot to the Motorola PrPMC800 and
possibly the Force Computer PowerPMC-260.
As anyone already done the port to these boards?
See URL:
http://mcg.motorola.com/cfm/templates/product.cfm?PageID=925&ProductID=175&PageTypeID=1
And URL:
http://www.forcecomputers.com/products/viewDetail.cfm?productTypeID=2&productID=144
The goal is to boot Linux from and IDE drive which the boot firmware of
these boards do not support. I don't have the Motorola hardware yet (
delivery is six to eight weeks! ) but it is the intended hardware for the
project I'm working on. I do have the Force Computer hardware right now.
So, I may proceeded to port U-Boot to it first and do my the remainder of
the Linux development work with it in the mean time.
Brgds,
Mark.
