Dear Simon Glass,

> 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.
