Hi, I am now able boot the mips port on a Sibyte 1250 processor on the SWARM reference platform. You can find more details about the processor here (including user manual): http://www.broadcom.com/products/Enterprise-Networking/Communications-Processors/BCM1250 http://www.broadcom.com/products/Enterprise-Networking/Communications-Processors/BCM91250A Some details about my setup: - 2GB of memory (cannot use all of it since some is mapped beyond 4GB) - Kernel is netbooted by the CFE - Root filesystem comes off a compact flash card connected via parallel ATA or a USB stick. - bge ethernet card on the PCI expansion slot for network connectivity - Using CFE to read and write from the console Things that still remain to be done are mostly to enable the devices on the chip (e.g. uart, gigabit ethernet, pcmcia) and also to start using the second core. Most of my changes were platform-dependent however I had to make some changes to: - busdma (to deal with physical memory beyond the directly mapped window) - pmap (zero pages through cacheable direct mapped window) - interrupts (allow masking and unmasking of shared interrupts) I don't want to keep holding diffs against -current for this, so I was hoping to get this checked in. How do I go about doing that? best Neel Boot log: CFE version 1.4.0 for SWARM (64bit,MP,LE,MIPS) Build Date: Sat May 5 17:32:29 PDT 2007 (neelnatu@sim19) Copyright (C) 2000,2001,2002,2003,2004,2005 Broadcom Corporation.
