From f8dd311982c86141f4f2fd326c0edf0c2d9fd97b Mon Sep 17 00:00:00 2001 From: Sylvain Munaut Date: Sun, 26 Mar 2006 13:37:38 +0200 Subject: [PATCH] ppc32: Adds support for the LITE5200B dev board ppc32: Adds support for the LITE5200B dev board This LITE5200B devboard is the new development board for the Freescale MPC5200 processor. It has two PCI slots and so a different PCI IRQ routing.
