From mboxrd@z Thu Jan 1 00:00:00 1970 From: Mike Looijmans Date: Tue, 26 May 2020 10:20:26 +0200 Subject: [PATCH] board: xilinx/zynqmp: Remove 1-second delay at boot Message-ID: <20200526082026.18898-1-mike.looijmans@topic.nl> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de SPL boot is slow on the ZynqMP because of this delay. The initialization done in psu_init no longer requires an external delay, so this can be removed to speed up the SPL boot flow considerably.
