No. All boards that PPCBoot was ported to started as "custom  boards"
like  yours. Until somebody adapted PPCBoot, and send me the patches.
Then  a  new  "standard"  configuration  was  added  to  the  PPCBoot
distribution.

Right.

The best documentation you can get so far is the  README  that  comes
with the PPCBoot sources, and the source cod eitself, of course.

Yes indeed, it's not that hard once you understand that the 8bit flash
has to be accessed little endian style when trying to program it (i.e.
address X in a CPU view is address X xor 3 on the flash address lines
and vise versa). I didn't finish the port yet though. Mainly because
I'm quite satisfied with what it does right now. I will of course
submit my code to the community once it's finished.

regards
Matthias

you can also use the askenv command.

Re: [Ppcboot-users] Mvista Kernel and PPCboot on FADS

Dave Ellis had sent me a patch to use the kernel 2.4.4 of ftp.denx.de for 
the FADS.
I attach it for you again so you don't need to extract it from the mailing 
lists web interface.

Here is the original thread:

RE: [Ppcboot-users] Want FADS patch for kernel

I haven't used this kernel too much yet, but it seems solid so far
(Thanks Wolfgang!). The FADS modifications are cleaner than with
some of the older MontaVista kernels I had been using.

Wolfgang's Linux 2.4.4 kernel source:
ftp://ftp.denx.de/pub/LinuxPPC/usr/src/linux-2.4.4-2001-05-12.tar.bz2

Use the attached patch (fadsnc.patch), build it with fads860_defconfig
(also attached). I use this:

   make zImage 2>&1 | tee make.out
   mkimage -n '2.4.4-2001-05-12 NFS SCC1 FADS 860T' \
         -A ppc -O linux -T kernel -C gzip -a 00000000 -e 00000000 \
         -d arch/ppc/coffboot/vmlinux.gz image
   # /tftpboot/image links to this target:
   cp image /opt/hardhat/devkit/ppc/8xx/target/boot

to build the image file and then boot it with bootp.

Sorry, but I can't help much with this. I don't have 16MB for my 
FADS and my real target board uses only SDRAM.

Thank you very much. This one works.

Where did you get this patch? Or has it been made by you?

Wolfgang, I was just wondering, is this that patch I wrote and sent you?
