// This structure allows a sparse set of keys to be redefined
// or a complete redefinition of the keyboard layout. Most
// keyboards have a lot of commonality in their layouts, therefore
// only defining those keys that need to change from the default
// minimizes the passed in information.
//
// Additionally, when an update occurs, the active keyboard layout
// will be switched to the newly updated keyboard layout. This
// allows for situations that when a keyboard layout driver is
// loaded as part of system initialization, the system will default
// the keyboard behavior to the new layout.
//
// Each call to update the keyboard mapping should contain the
// complete set of key descriptors to be updated, since every
// call to the HII which contains an EFI_HII_KEYBOARD_PACK will
// wipe the previous set of overrides. A call to
