From mboxrd@z Thu Jan 1 00:00:00 1970 From: Andreas Galauner Date: Wed, 1 Aug 2018 00:00:38 +0200 Subject: [U-Boot] [PATCH 1/1] arm: zynq: Fix device tree for Avnet Picozed boards Message-ID: <20180731220038.15675-1-andreas@galauner.de> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de This change adds the necessary /chosen/stdout-path to the device tree for the Avnet Picozed boards. This node is mandatory for the SPL. Without it the board resets in a loop without any output. The change also adds the USB, QSPI and Ethernet MAC nodes of the corresponding devices present on the board.
