Sorry for the mailbox flooding, I'm slowly learning to step back and look at things before jumping to conclusions. Geode and i586 also have ROM_CODE_SEG defined, this didn't, that's why the jump was going to nowhere. Do those defines belong in this file, somewhere else, or in Kconfig? Are the i586 values the same as they should be for c7?
ROM_CODE_SEG is probably the same for all x86 but we did not want to assume anything.
I'm now getting hung up because XIP_ROM_[SIZE,BASE] isn't defined. Do we still need XIP and those defines? Are the value limitations the same as they were in v2?
XIP, hmm. Those are now called CONFIG_XIP_*. Although what meaning they have in v3 is questionable to me. I have never used it.
Note the error in this snippet from arch/x86/i586/stage0.S
#if defined(CONFIG_XIP_ROM_SIZE) && defined(CONFIG_XIP_ROM_BASE) /* enable write base caching so we can do execute in place * on the flash rom. */ movl $0x202, %ecx xorl %edx, %edx movl $(XIP_ROM_BASE | MTRR_TYPE_WRBACK), %eax ^^^^^^^^^^^^^^^^^ WRONG NAME! wrmsr

I would LOVE to have the CN7 on V3 for this show: http://sc08.supercomputing.org/
we always show off coreboot there. Most important is k8, but via would be nice too. ron

Once CAR's running, the rest of initram should be a breeze (and I can actually do it up right, too!). The hardest part after that will be the dts :p

given an lspci I can give you an initial dts.
how about we start committing bits of your work soon :-)

Oops, I meant to respond to this. It seems that file is the only place CONFIG_XIP* shows up:
corey@Mobulus:~/coreboot/coreboot-v3$ grep -rn CONFIG_XIP * arch/x86/i586/.svn/text-base/stage0.S.svn-base:245:#if defined(CONFIG_XIP_ROM_SIZE) && defined(CONFIG_XIP_ROM_BASE) arch/x86/i586/stage0.S:245:#if defined(CONFIG_XIP_ROM_SIZE) && defined(CONFIG_XIP_ROM_BASE)
I'm gonna try commenting out the XIP stuff and seeing what it does.
Thanks, Corey
