+Subject: [PATCH 1/2] BaseTools: fix ucs-2 lookup on python 3.9
+
+python3.9 changed/fixed codec.register behavior to always replace
+hyphen with underscore for passed in codec names:
+
+  https://bugs.python.org/issue37751
+
+So the custom Ucs2Search needs to be adapted to handle 'ucs_2' in
+addition to existing 'ucs-2' for back compat.
+
+This fixes test failures on python3.9, example:
+
+======================================================================
+FAIL: testUtf16InUniFile (CheckUnicodeSourceFiles.Tests)

+Subject: [PATCH 2/2] BaseTools: Work around array.array.tostring() removal in
+ python 3.9
+
+In python3, array.array.tostring() was a compat alias for tobytes().
+tostring() was removed in python 3.9.
+
+Convert this to use tolist() which should be valid for all python
+versions.
+
+This fixes this build error on python3.9:
