// 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
