From mboxrd@z Thu Jan 1 00:00:00 1970 From: Becky Bruce Date: Wed, 3 Dec 2008 23:04:44 -0600 Subject: [U-Boot] [PATCH 08/11] mpc8641hpcn: Clean up PCI mapping concepts In-Reply-To: <1228367087-27268-1-git-send-email-beckyb@kernel.crashing.org> References: <1228367087-27268-1-git-send-email-beckyb@kernel.crashing.org> Message-ID: <1228367087-27268-9-git-send-email-beckyb@kernel.crashing.org> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de Clean up PCI mapping concepts in the 8641 config - rename _BASE to _BUS, as it's actually a PCI bus address, separate virtual and physical addresses into _VIRT and _PHYS, and use each appopriately.
