This is the main PEIM file for TXT. It represents an abstract outline of the
|
|
steps required during PEI for enabling TXT. Each individual step is further
|
|
abstracted behind a function call interface. This is intended to minimize
|
|
the need to modify this file when porting TXT to future platforms.
