From aaad108b889c6980a2d05262a2f7febb14f94d68 Mon Sep 17 00:00:00 2001 From: "Kim B. Heino" Date: Fri, 12 Mar 2010 15:46:56 +0200 Subject: USB storage count Here's another USB storage patch. Currently U-Boot handles storage devices #0 - #4 as valid devices, even if there is none connected. This patch fixes usb_stor_get_dev() to check detected device count instead of MAX-define. This is very important for ill behaving devices. usb_dev_desc[] can be partially initialized if device probe fails. After fixing get_dev() it was easy to fix "usb part" etc commands. Previously it outputed "Unknown partition table" five times, now it's "no USB devices available". Signed-off-by: Kim B.
