From 78994e240fce03832ceebc875c43773a2c615e79 Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Mon, 31 Dec 2007 16:41:15 +1100 Subject: [PATCH] [POWERPC] 4xx: PCIe: Increase max busses per port to 64 Because of how big mapping the config space is (1M per bus), we limit how many busses we support for now. In the long run, we could replace that with something akin to kmap_atomic instead. This patch changes the limit from currently 16 to 64.
