/** @file
Provides a service to retrieve a pointer to the start of HOB list.
Only available to DXE module types.
This library does not contain any functions or macros. It simply exports a global
pointer to the start of HOB list as defined in the Platform Initialization Driver
Execution Environment Core Interface Specification. The library constructor must
initialize this global pointer to the start of HOB list, so it is available at the
module's entry point. Since there is overhead in looking up the pointer to the start
of HOB list, only those modules that actually require access to the HOB list
should use this library.
