Description

Hello everyone,

I just tried to build a new coreboot.rom for my Thinkpad X220.

The build fails because the payload (tianocore) does not fit into the (standard) CBFS (1MB) anymore.

It turns out: The bootblock size increased from < 5KB to over 60 KB in the latest master build.
Tianocore has roughly the same size, a little less actually.
In the last build the empty space was around 3KB. If bootblock size hadn't increased by that much, it would've been a fit.

Unfortunatly I have no knowledge about how the bootblock (size) is affected by or build in coreboot. I did not find any specific documentation on this regard in docs.coreboot.org.

I'd really appreciate information/hints about how I can tackle this issue myself or how I can provide you with information needed to investigate this behavior.
