From 90f06e9d20a402311b89b08eff5e1e0f2c987840 Mon Sep 17 00:00:00 2001 From: Ashok Reddy Soma Date: Wed, 7 Oct 2020 00:36:54 -0600 Subject: [PATCH] arm64: versal: Update mini u-boot eMMC node parameters Mini u-boot eMMC dt parameters are not in sync with full u-boot dt. Frequency for eMMC is fixed to 25Mhz. Due to this, mmc multi-block write commands are failing. Increase frequency to 200Mhz to fix this issue. Add bus-width = <8>, non-removable and disable-wp properties to the node as this is eMMC.
