Subject: [PATCH 1/5] ARM: at91: Add PBL_BREAK support
X-SA-Exim-Version: 4.2.1 (built Wed, 08 May 2019 21:11:16 +0000)
X-SA-Exim-Scanned: Yes (on metis.whiteo.stw.pengutronix.de)
This adds PBL_BREAK support to the barebox at91 header.
Since we're here, let's set the header parameters to the defaults
for the barebox and do some code formatting to improve readability.
