From 89d63fe179520b11f54de1f26755b7444c79e73a Mon Sep 17 00:00:00 2001 From: Atsushi Nemoto Date: Fri, 11 Jul 2008 00:33:08 +0900 Subject: [MIPS] TXx9: Reorganize PCI code Split out PCIC dependent code and SoC dependent code from board dependent code. Now TX4927 PCIC code is independent from TX4927/TX4938 SoC code. Also fix some build problems on CONFIG_PCI=n. As a bonus, "FPCIB0 Backplane Support" is available for all TX39/TX49 boards and PCI66 support is available for all TX49 boards.
