From 2385a6d8ed66aa31bd358b55441ca2f780b4324e Mon Sep 17 00:00:00 2001 From: Michal Simek Date: Mon, 8 Jan 2024 16:39:20 +0100 Subject: [PATCH] arm64: zynqmp: Introduce u-boot options node with bootscr-address Add u-boot options node with details about bootscr-address. c&p description from dtschema/schemas/options/u-boot.yaml: "Holds the full address of the boot script file. It helps in making automated flow easier by fetching the 64bit address directly from DT. Value should be automatically copied to the U-Boot 'scriptaddr' variable. When it is defined, bootscr-ram-offset property should be ignored. Actually only one of them should be present in the DT." Address is generic for all zynqmp boards because all of them have DDR starting from 0. Custom boards should revisit the location and aligned it based on their needs.
