Subject: [PATCH v3] ARM: imx: Add Support for Webasto ccbv2
Date: Wed, 14 Oct 2020 08:18:58 +0200	[thread overview]
Message-ID: <20201014061857.28101-1-r.czerwinski@pengutronix.de> (raw)

[-- Warning: decoded text below may be mangled, UTF-8 assumed --]
[-- Attachment #1: Type: text/plain, Size: 28102 bytes --]

Add support for the Webasto Common Communication Board Version 2. The
device tree included with barebox can eventually be replaced with the
required barebox changes when the ccbv2 device tree is upstream.

Signed-off-by: Rouven Czerwinski <r.czerwinski@pengutronix.de>
---
v2 ��� v3:
- Added SPDX license identifier to the flash header
- Combined initcalls and moved to board driver
- Removed unnecessary CONFIG_DEBUG_LL check
- Added board to defconfig and tested defconfig compilation

v1 ��� v2:
This should address all comments from the previous patch series,
thanks to Sascha, Ahmad and Roland for the review.
- Barebox should now correctly chainload if early OP-TEE was loaded
- DTS files have been split up
- Uses the iomux file for i.MX6UL to setup the UART instead of magic
  values
- Application of the overlay checks the board compatible before
  application of the overlay.
