From a9d2b105ccd23e07e3dd99d010a34bd5d1c95b42 Mon Sep 17 00:00:00 2001
From: Daniel Golle <daniel@makrotopia.org>
Date: Sat, 13 Jan 2018 18:35:59 +0100
Subject: [PATCH 1/3] ARM: dts: rename oxnas dts files
Other platforms' device-tree files start with a platform prefix, such as
sun7i-a20-*.dts or at91-*.dts.
This naming scheme turns out to be handy when using multi-platform build
systems such as OpenWrt.
Prepend oxnas files with their platform prefix to comply with the naming
scheme already used for most other platforms.

From 71270226b14733a4b1f2cde58ea9265caa50b38d Mon Sep 17 00:00:00 2001
From: Adrian Panella <ianchi74@outlook.com>
Date: Thu, 9 Mar 2017 09:37:17 +0100
Subject: [PATCH 67/69] generic: Mangle bootloader's kernel arguments
The command-line arguments provided by the boot loader will be
appended to a new device tree property: bootloader-args.
If there is a property "append-rootblock" in DT under /chosen
and a root= option in bootloaders command line it will be parsed
and added to DT bootargs with the form: <append-rootblock>XX.
Only command line ATAG will be processed, the rest of the ATAGs
sent by bootloader will be ignored.
This is usefull in dual boot systems, to get the current root partition
without afecting the rest of the system.

+ bool "Append rootblock parsing bootloader's kernel arguments"
+ help
+ The command-line arguments provided by the boot loader will be
+ appended to a new device tree property: bootloader-args.
+ If there is a property "append-rootblock" in DT under /chosen
+ and a root= option in bootloaders command line it will be parsed
+ and added to DT bootargs with the form: <append-rootblock>XX.
+ Only command line ATAG will be processed, the rest of the ATAGs
+ sent by bootloader will be ignored.
