From f75dc784fcce676848c3c5c3d726be44c274a551 Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Mon, 10 Feb 2014 13:11:53 -0700 Subject: ARM: tegra: set CONFIG_SYS_USB_EHCI_MAX_ROOT_PORTS Tegra's EHCI controllers only have a single PORTSC register. Configure U-Boot to know this. This prevents e.g. ehci_shutdown() from touching non-existent registers.
