From 0eed87ed9047a42269369be1fdc5b64c42c15476 Mon Sep 17 00:00:00 2001 From: Pragnesh Patel Date: Fri, 29 May 2020 11:33:25 +0530 Subject: [PATCH] riscv: sifive: dts: fu540: Add board -u-boot.dtsi files Devicetree files in FU540 platform is synced from Linux, like other platforms does. Apart from these U-Boot in FU540 would also require some U-Boot specific node like clint. So, create board specific -u-boot.dtsi files. This would help of maintain U-Boot specific changes separately without touching Linux dts(i) files which indeed easy for syncing from Linux between releases.
