And here is a second draft with more infos.
Booting the Linux/ppc64 kernel without Open FirmwareThanks a lot for taking the initiative to come to an agreement about the kernel boot interface.
I have some concerns about the memory foot print and increased boot time that will result from the proposed solution. There are many embedded systems where resources are tight and requirements are aven tighter. It would be probably a good idea to also ask for feedback from these folks - for example by posting your RFC on the celinux-dev mailing list.
But my biggest concern is that we should try to come up with a solution that has a wider acceptance. Especially from the U-Boot point of view it is not exactly nice that each of PowerPC, ARM and MIPS use their very own, completely incompatible way of passing in- formation from the boot loader to the kernel.
As is, your proposal will add just another incompatible way of doing the same thing (of course we will have to stay backward compatible with U-Boot to allow booting older kernels, too).
Why don't we try to come up with a solution that is acceptable to the other architectures as well?
Maybe you want to post the RFC to lkml, or at least to the linux-arm-kernel and linux-mips mailing lists?
I'm really interested in having this discussion.
I'm forced to maintain my own u-boot based solution for doing this and I'd be very interested in whatever gets chosen.
IMHO the current mess is considerable, and at this point I wouldn't really care if the resulting solution is less than optimal, as long as there is one.
Best regards,
