Subject: [PATCH 1/5] Remove the errata fix codes for MPC8641 silicon ver 1.0 which is end of life.
Date: Tue, 22 May 2007 11:38:26 +0800	[thread overview]
Message-ID: <11798051101543-git-send-email-wei.zhang@freescale.com> (raw)
In-Reply-To: <11798051102658-git-send-email-wei.zhang@freescale.com>

Remove the errata fix codes for MPC8641 silicon ver 1.0 which
is end of life.

The MPC8641 silicon ver 1.0 is not fully support PCI/PCI Express
specifications. The revision 2.0 fixes all of these errata
and the rev 1.0 silicon is end of life. So errata codes are removed.

Now, The chip is full compatible with PCI/PCI Express
specifications. The generic PCI code is used.
