From 5924486dc0f205ebc2bbf4c262eec902ff38e802 Mon Sep 17 00:00:00 2001 From: Russell King Date: Thu, 22 Jun 2006 15:05:36 +0100 Subject: [ARM] nommu: add stubs for ioremap and friends nommu doesn't have any form of remapping support, so ioremap, etc become stubs which just return the casted address, doing nothing else. Move ioport_map(), ioport_unmap(), pci_iomap(), pci_iounmap() into a separate file which is always built.

Since this also removes iotable_init() and iotable_init() is used extensively in the platform support files, just make it a no-op. Based upon a couple of patches by Hyok. Signed-off-by: Hyok S.
