/** @file
|
|
This file declares the Boot Script Executer PPI.
|
|
|
|
This PPI is published by a PEIM upon dispatch and provides an execution engine for the
|
|
Framework boot script. This PEIM should be platform neutral and have no specific knowledge of
|
|
platform instructions or other information. The ability to interpret the boot script depends on the
|
|
abundance of other PPIs that are available. For example, if the script requests an SMBus command
|
|
execution, the PEIM looks for a relevant PPI that is available to execute it, rather than executing it
|
|
by issuing the native IA-32 instruction.
