Subject: [PATCH 0/7] powerpc/85xx: p2020: Create one unified machine description
Date: Fri, 19 Aug 2022 21:15:50 +0200	[thread overview]
Message-ID: <20220819191557.28116-1-pali@kernel.org> (raw)

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
