[U-Boot-Users] i386 port of ppcboot
Hello all,
I have made a preliminary port of ppcboot to i386 processors. The code runs on a AMD SC520 CDP (AMD reference design for the SC520 486 system on a chip device) and boots a linux kernel to promt from the on board flash. I am in the process of making a patch file and finding some web-spece to publish it on, I will announce when the patch is availabe on the web. If anyone wants to see it right now, you can email me and ask for the patch (~38kb compressed).
The code is based on a ppcboot cvs-snapshot from October 28, but I intend to move to U-boot as soon as I have pulished the first version.

Can this boot a standard linux kernel?
I do not know much about the x86 world but don't linux need some functions from BIOS to start?

Yes, with or without the ppcboot header.

Yes, those three or four BIOS calls that are needed are emulated. /Daniel

Can you post it to the list? 38 kB shouldn't be that bad.
How do you access the SC520 flash? Do you have some kind of a JTAG tool for it?

Congratulations! Excellent job!

Please post it to the list (the size limit of 40 k should permit); plase add an explicit "Cc: wd@denx.de" just in case.
The code is based on a ppcboot cvs-snapshot from October 28, but I intend to move to U-boot as soon as I have pulished the first version.
There is probably only little significant change since then, so I should be able to merge your patch directly.
Thanks for this valuable contribution!
Best regards,

Ok, I will post a patch that I am preparing later today.

Please go ahead if you like.
