Attached is a patch to add generic base support for systems based on the OMAP 1 family. The devices supported in this patch are serial console and MPU timers for OS timing purposes. This patch depends upon patches previously sent by Scott Allan: "Three small patches for ARM" on 07/26/2006 and "Patch to add support for ARM9E" on 07/31/2006. A staggering number of mobile phones, PDAs, and other portable devices are based on these systems, and OMAP would make a great addition to NetBSD. If there are any concerns we can address or other things we can do to get this code accepted upstream please let me know, thanks,
