From 29e5c027889ed583fd04d87927e714201b47a225 Mon Sep 17 00:00:00 2001 From: Patrick Delaunay Date: Thu, 15 Oct 2020 14:52:30 +0200 Subject: [PATCH] board: stm32mp1: no MTD partitions fixup for serial boot Remove the update of the MTD partitions in kernel device tree for serial boot (USB / UART), and the kernel will use the MTD partitions define in the loaded DTB because U-Boot can't known the expected flash layout in this case.
