From a3a01ac9f0b914e7a2454a26e40aa29e31b8640b Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Wed, 13 Mar 2019 17:49:29 +0100 Subject: [PATCH] test/py: mmc: Add 'mmc read' performance check Add option to the mmc rd test to check the duration of the execution of the mmc read command. This allows intercepting read performance regressions.
