Need help implementing romstage CBMEM

[Keith Hui]

Hi all,

After reading the code for more recent Intel northbridges I think I
have an idea on what needs to be added, so here is my attempt to bring
440BX to coreboot 4.7 standards:

The problem is it could not boot. The console log is attached.

In short, I think I have the top of RAM value correct, but it could
not find a place for the payload to load and the boot process is
stuck.

What am I missing?

By the way, I think an unintended update for my two earlier patches
were also pushed along with this change. How to I get them sorted out?
