+From 86cc911aaa958fedf2ea9cb04b4af17f5357815d Mon Sep 17 00:00:00 2001
+From: Anton Gerasimov <anton.gerasimov@here.com>
+Date: Fri, 1 Feb 2019 14:39:48 +0100
+Subject: [PATCH] board: raspberrypi: add serial and revision to the device
+ tree
+
+Raspberry Pi bootloader adds this node to fdt, but if u-boot script
+doesn't reuse the tree provided by it, this information is lost.
+
+Revision and serial are displayed in /proc/cpuinfo after boot.
