* kFreeBSD headers:
   Patched version in http://people.debian.org/~rmh/kfreebsd-mipsel/kfreebsd-mipsel-headers.tar.gz
   (patch is included in kfreebsd-kernel-headers package too, but needs update)

 * binutils:
   Use latest CVS, or otherwise 2.20.1 with patch from http://people.debian.org/~rmh/kfreebsd-mipsel/binutils-2.20.1.diff

 * GCC:
   Patch for GCC 4.4 in http://people.debian.org/~rmh/kfreebsd-mipsel/gcc-4.4.4.diff
   Upstream won't merge it yet because of timing in their release cycle (we need to wait untill GCC 4.6 is branched).
   Build with {{{--disable-tls}}} as TLS is not supported yet.

 * GDB:
   Apply patch from http://sourceware.org/ml/gdb-patches/2011-01/msg00178.html on top of latest CVS.

 * Debian EGLIBC
   Get latest Debian package of eGlibc (including Debian patchset!!). Resync with latest kfreebsd port SVN (http://svn.debian.org/viewsvn/glibc-bsd/trunk/glibc-ports/) and apply patches/mips_mktime.patch as well.
   Build with {{{--without-__thread}}} as TLS is not supported yet.
   CFLAGS="-march=mips64 -O2 -g" is recommended.
   Dynamic linker doesn't work yet, use -static when building programs.

 * init: to build a minimal system, cross-compile bash and then you can use the following shell script as init:
   {{{
\#!/bin/sh
exec < /dev/console > /dev/console 2> /dev/console

export PATH=/usr/sbin:/usr/bin:/sbin:/bin
export HOME=/root
export PS1="\h:\w# "
export CFLAGS="-static -g -march=mips64"

mount -o rw /

cd $HOME

while : ; do
  /bin/sh
done
}}}

 * kFreeBSD (kernel of FreeBSD): 
   Image for MALTA available from kfreebsd-image-*-malta package (e.g. http://packages.debian.org/kfreebsd-image-8.2-1-malta).
   Tested on gxemul (see below).

 * Build disk image:
   {{{
   /usr/sbin/makefs /tmp/mips.img directory
   }}}

 * Run with gxemul:
   {{{
   gxemul -e malta -C 4Kc kfreebsd-*-malta -x -M 256 -d i:/tmp/mips.img
   }}}

 * Run with qemu (note: this doesn't work yet):
   {{{
   qemu-system-mipsel -M malta -kernel kfreebsd-*-malta -serial /dev/tty
   }}}
