From 56e403d95fc00304e87565712f34e0f2107a33c4 Mon Sep 17 00:00:00 2001 From: Andre Przywara Date: Mon, 27 Apr 2020 19:18:03 +0100 Subject: [PATCH] arm: juno: enable USB The Juno board features a standard compliant EHCI/OHCI USB host controller pair, which we can just enable. The platform data is taken from the device tree. This allows to use USB mass storage (the only storage on a Juno r0) for loading. At least on my board USB seems a bit flaky, I need two "usb reset" sequences after the "usb start" to detect an USB hard drive.
