PS37: 
Yesterday, I attempted to ensure that the fatcat mainboard could be built using only the minimal code for the PTL SOC. However, it appears that due to the introduction of common code and the separation of the various stage dependencies, we will not be able to build the fatcat mainboard code using only the bootblock/minimal code. In order to build fatcat correctly, we must land the code in the following order:

1. bootblock
2. romstage
3. gpio
4. ramstage
5. ACPI/ASL
6. Finally, google/fatcat

Therefore, my recommendation is to follow this order and keep the mb code at the top of each CL. This way, we can only land the CLs from the bottom of #6, which will ensure that the fatcat mainboard build is successful.
