From adc5701134f7041d7f767b672b66afb8b64ba5ce Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Fri, 6 Jul 2018 10:27:16 -0600 Subject: [PATCH] binman: Tidy up variables in _RunMicrocodeTest() At present we call the three entries first, second and third. Rename them to reflect their contents instead, for clarity.
