oxnas: drop target

Browse Source 
The Upstream Linux community has discontinued support for the target.
Maintaining support for it downstream would require too much effort.
Moreover, it seems that the supported hardware is no longer deemed worthy
of it.

From df9fb90120423c4c55b66a5dc09af23f605a406b Mon Sep 17 00:00:00 2001
From: Daniel Golle <daniel@makrotopia.org>
Date: Mon, 1 Dec 2014 21:37:25 +0100
Subject: [PATCH] disk/part.c: use unsigned format when printing capacity
To: u-boot@lists.denx.de
Large disks otherwise produce highly unplausible output such as
Capacity: 1907729.0 MB = 1863.0 GB (-387938128 x 512)
As supposedly all size-related decimals are unsigned, use unsigned
format in printf statement, resulting in a correct capacity being
displayed:
Capacity: 1907729.0 MB = 1863.0 GB (3907029168 x 512)

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.
Signed-off-by: Adrian Panella <ianchi74@outlook.com>
