[U-Boot] [PATCH v9 1/5] usb: ehci: prevent bad PORTSC register access

2013-05-15 Thread Kuo-Jung Su
From: Kuo-Jung Su 1. The 'index' of ehci_submit_root() is not always > 0. e.g. While it gets invoked from usb_get_descriptor(), the 'index' is always a '0'. (See ch.9 of USB2.0) 2. The PORTSC register is not always required, and thus it should only report a port error when necessary
