From 361377dbdbc9f0f59b954248a696ad46ad5036b7 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Sat, 11 Apr 2020 20:50:24 +0200 Subject: [PATCH] ARM: rmobile: Merge prior-stage firmware DT fragment into U-Boot DT on Gen3 The prior-stage firmware generates DT fragment containing the /firmware node, /reserved-memory node and /memory@ nodes. Merge these nodes into the U-Boot DT, so U-Boot can use this information.
