Subject: [PATCH 4/5] Set RC of mpc8641 to transparent bridge for transfer legacy I/O access.
Date: Tue, 22 May 2007 11:38:29 +0800 [thread overview]
Message-ID: <11798051102051-git-send-email-wei.zhang@freescale.com> (raw)
In-Reply-To: <1179805110278-git-send-email-wei.zhang@freescale.com>
Set RC of mpc8641 to transparent bridge for transfer legacy I/O access.
Now, the children bus could use the I/O resource of the host bridge.
Note: The 0x7010 is the device ID of host bridge for MPC8641 and
0x7011 is the device ID of host bridge fro MPC8641D.
