Subject: [U-Boot] [PATCH v2 5/7] usb: usbeth: smsc95xx: remove EEPROM loaded check
Date: Thu, 13 Dec 2012 18:21:30 -0800	[thread overview]
Message-ID: <1355451692-28017-6-git-send-email-sjg@chromium.org> (raw)
In-Reply-To: <1355451692-28017-1-git-send-email-sjg@chromium.org>

From: Michael Spang <spang@chromium.org>

[port of Linux kernel commit bcd218be5aeb by Steve Glendinning]

The eeprom read & write commands currently check the E2P_CMD_LOADED_ bit is
set before allowing any operations.  This prevents any reading or writing
unless a correctly programmed EEPROM is installed.
