How are we going to support code that runs at a fixed address? I can only come up with these two options. I think the PIE stuff from v3 is not an option: we've been warned about it for a while now, and I now believe the warnings. > 4. Geode ROM handling in CBFS. > a.

But, we're at step 1b and we need to make a decision. Our current decision, by default, is 'use ldscripts to create fallback and normal images, not cbfs'. If you look at how the normal symbol is created in the fallback image, I don't see that fixed-location cbfs files are any uglier ... ron -- coreboot mailing list: [email protected] http://www.coreboot.org/mailman/listinfo/coreboot
