This is a potentially good pointer to where someone can take this.
While startup was working, BSP now explodes once the AP stops, while
BSP is doing startup IPI loop send #2. The code needs to be hardened; I
think use of the shared variables would really make it much more solid.
This would be a good undergrad student project if someone is looking for one.

adaption of the v2 code, with significant cleanup and
simplification. It also works in CAR mode, and has no .bss or .data
usage. It provides for a way to provide AP POST codes to the BSP.
Since one common file with amd changed (lapic.h) I have build-tested this
against serengeti and it is fine.
It builds and I'll be testing it as soon as I can find the power supply for
the kontron (it got "borrowed").

new file. Basically an adaptation of the v2 code to v3. All global variables
removed. One big change to note: there is a stack struct, and the
parameters to the secondary_start are struct members. Thus the BSP
can watch the AP, and, neater, the AP can POST to a shared variable
and the BSP can see how far it got.

that has already been done by the BSP. For single processor systems the CPU
flag is always 0, BSP. This code also moves the AP stop for K8 mainboards to
after memory setup so the AP's MTRRs can be setup to match system memory.

etherboot.
The fix is to replace the wbinvd with an invd. The wbinvd is a bad idea,
since the cache at this point is full of tags to a location that is not backed
by memory.
