[coreboot] V2 Multiboot

[Jordan Crouse]

Having a copious amount of time on my hands right now, I had occasion to 
review the coreboot v2 multiboot patch from some time back.

http://www.coreboot.org/pipermail/coreboot/2008-September/039364.html

It looks technically correct, and it compiles and works.  I did see one 
issue:

Here is the memory map from the coreboot table by way of coreinfo:

-- Memory Map --

Table: 0000000000000000 - 0000000000000fff

RAM: 0000000000001000 - 00000000000effff

Table: 00000000000f0000 - 00000000000fffff

RAM: 0000000000100000 - 0000000007ffffff

And the multiboot map, also courtesy of coreinfo:

-- Memory Map --

Reserved: 0000000000000000 - 0000000000000527

Reserved: 00000000000f0000 - 00000000000f0457

RAM: 0000000000000528 - 00000000000effff

RAM: 00000000000f0458 - 0000000007ffffff

Multiboot is being rather generous in giving back memory to the system - 
I think that the two table should match - or failing that, at least 
multiboot should round up to the nearest 4k page.  V3 has the same issue.

Other then that, I'm cool with acking this.
