From a6475c132278c1be158a13872c233aeab8a00176 Mon Sep 17 00:00:00 2001 From: Michal Simek Date: Mon, 18 Jan 2010 15:27:10 +0100 Subject: microblaze: Enable PCI, missing files There are two parts of changes. The first is just enable PCI in Makefiles and in Kconfig. The second is the rest of missing files. I didn't want to add it with previous patch because that patch is too big. Current Microblaze toolchain has problem with weak symbols that's why is necessary to apply this changes to be possible to compile pci support. Xilinx knows about this problem.
