From 03ebc20de3b30fca5230a4c73cf4494b0d8d8d08 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Tue, 6 Jul 2021 10:36:41 -0600 Subject: binman: Add basic support for debugging performance One of binman's attributes is that it is extremely fast, at least for a Python program. Add some simple timing around operations that might take a while, such as reading an image and compressing it. This should help to maintain the performance as new features are added. This is for debugging purposes only.
