Reverting everthing would be overkill.. The only thing that negatively affects the build is the ROMBASE configuration in src/arch/i386/Kconfig, the other parts are fine.
I'm looking for a way to keep ROMBASE functional that way (esp. to allow smaller bootblocks) while fixing the current issue.
I think we should allow larger boot blocks at the same time and fix fam10 builds.
Maybe it's still a good idea to revert that change for now.
It's up to you. Reverting it seems cheap compared to having it broken for multiple days.
Thanks, Myles
