/* *** Overview ***
There has been a trend to create more HWPs that process raw data.
This allows Hostboot and Cronus (and other platforms to share more code.
The trick is that we generally want to call these HWPs inside what has
traditionally been Hostboot-only code. The fapiwrap directory will help
encapsulate all of the calls to ekb code in one place. That way if we
ever need to remove HWPs/EKB code it will be easier to stub out the calls.
We have found in the past we have contaminated a lot of Hostboot-only
code with calls to EKB code. This directory should help address that problem.
