From d282c1d9e744dea4c7b3a8de63c1c77c16bf3a7c Mon Sep 17 00:00:00 2001 From: Amit Kumar Mahapatra <amit.kumar-mahapatra@amd.com> Date: Mon, 11 Sep 2023 16:10:47 +0200 Subject: [PATCH] arm64: versal: Add no-wp DT property in OSPI flash node Added no-wp DT property in OSPI flash node for all board dts & dtsi files on which the WP# signal of the OSPI flash device is not connected. If this property is set, then the software will avoid setting the status register write disable (SRWD) bit in status register during status register write operation.
