Subject: [PATCH 1/3] boot/efi: Bring in a bunch of additional TianoCore EDK II
 headers.

Taken from the MdePkg of the UDK2017 branch of the
git://github.com/tianocore/edk2 repository.
All I modified was killing CRs using 'tr -d "\015"'.

This is a work in progress.

+/**
+  The function reads the next keystroke from the input device. If
+  there is no pending keystroke the function returns
+  EFI_NOT_READY. If there is a pending keystroke, then
+  KeyData.Key.ScanCode is the EFI scan code defined in Error!
+  Reference source not found. The KeyData.Key.UnicodeChar is the
+  actual printable character or is zero if the key does not
+  represent a printable character (control key, function key,
+  etc.). The KeyData.KeyState is shift state for the character
+  reflected in KeyData.Key.UnicodeChar or KeyData.Key.ScanCode .
+  When interpreting the data from this function, it should be
+  noted that if a class of printable characters that are
+  normally adjusted by shift modifiers (e.g. Shift Key + "f"
+  key) would be presented solely as a KeyData.Key.UnicodeChar
+  without the associated shift state. So in the previous example
+  of a Shift Key + "f" key being pressed, the only pertinent
+  data returned would be KeyData.Key.UnicodeChar with the value
+  of "F". This of course would not typically be the case for
+  non-printable characters such as the pressing of the Right
+  Shift Key + F10 key since the corresponding returned data
+  would be reflected both in the KeyData.KeyState.KeyShiftState
+  and KeyData.Key.ScanCode values. UEFI drivers which implement
+  the EFI_SIMPLE_TEXT_INPUT_EX protocol are required to return
+  KeyData.Key and KeyData.KeyState values. These drivers must
+  always return the most current state of
+  KeyData.KeyState.KeyShiftState and
+  KeyData.KeyState.KeyToggleState. It should also be noted that
+  certain input devices may not be able to produce shift or toggle
+  state information, and in those cases the high order bit in the
+  respective Toggle and Shift state fields should not be active.
