From 096aa229a9e5909e40865454208a6a009dc0c02b Mon Sep 17 00:00:00 2001 From: Bryan Brattlof Date: Thu, 27 Feb 2025 11:14:41 -0600 Subject: [PATCH] mach-k3: common_fdt: create a reserved memory node Some device trees may not have a reserved-memory node. Rather than exiting early we should create a new reserved-memory node along with the memory carveout for the firmware we (U-Boot) have placed.
