+/** @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.
