Subject: ide: Accept the IDLE (0xe3) ATA command.
X-Git-Tag: stable_2015_04_15~80
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=ecec8cde63666221dc29160629473247aac9a055;p=gem5.git

ide: Accept the IDLE (0xe3) ATA command.

This command is supposed to set up a timer which will put the drive into a
standby mode if it isn't sent a command within a given time out. Since most of
the timeouts are generally significantly longer than a simulation would run
anyway, and we don't have an implementation for standby mode to begin with,
we can accept the command, do nothing, and report success.
