First of all, INITIAL_EBDA_SEGMENT has been 0xF600 prior to this change.
OK, I guess it works then. At least most of the time anyway.
I believe loading a SeaBIOS payload will obliterate the coreboot EBDA at this location. SeaBIOS almost certainly replaces/updates the BDA and will position its own EBDA at an appropriate place.
I guess there is no need to go back to coreboot code at that point so this is OK. It just seems to me that it would be neater and more consistent if the EBDA were in an appropriate place to begin with.
What is the reason to have it up at 0xf6000? Linux will boot happily with it at 0x9c000 or even somewhat lower, as it must to boot with a standard BIOS.
