Subject: [PATCH 0/7] powerpc/85xx: p2020: Create one unified machine description

This patch series unifies all P2020 boards and machine descriptions into
one generic unified P2020 machine description. With this generic machine
description, kernel can boot on any P2020-based board with correct DTS
file.

Tested on CZ.NIC Turris 1.1 board with has Freescale P2020 processor.
Kernel during booting correctly detects P2020 and prints:
[    0.000000] Using Freescale P2020 machine description
