Subject: [PATCH 8/9] ram: stm32mp1: reduce delay after BIST reset for tuning
Date: Fri, 6 Mar 2020 11:14:10 +0100	[thread overview]
Message-ID: <20200306111355.8.I2ed443e2c15db6b007f836254b3753da9b06e76d@changeid> (raw)
In-Reply-To: <20200306101412.15376-1-patrick.delaunay@st.com>

Reduce the delay after BIST delay, from 1ms to 10us
which is enough accoriding datasheet.
