Subject: [PATCH 10/17] tests/tcg: clean up output of memory system test
Date: Fri, 13 Sep 2024 18:26:48 +0100	[thread overview]
Message-ID: <20240913172655.173873-11-alex.bennee@linaro.org> (raw)
In-Reply-To: <20240913172655.173873-1-alex.bennee@linaro.org>

This is useful information when debugging memory issues so lets
improve by:

  - include the ptr address for u8 fills (like the others)
  - indicate the number of operations for reads and writes
  - explicitly note when we are flushing
  - move the fill printf to after the reset
