This is a snapshot diff of my development tree.  So, no warranty what so
ever, like usual.

Don't hesitate to comment, fix bugs, or even send patches to me if you
feel like it!  :-)

This is quick and dirty...  just to give you some clues if you need them.


Step 1: Grab a fresh 2.2.1 source archive and untar it

	tar -xzf linux-2.2.1.tar.gz

Step 2: Grab the ARM patch for this kernel from the ARM Linux FTP site 
	and apply it

	gunzip < patch-2.2.1-rmk2.gz | patch -p0

Step 3: Apply the SA1100 patch

	gunzip < patch-2.2.1-rmk2-np1.gz | patch -p0

Step 4: Configure the kernel

	cd linux
	make config

Step 5: Make the kernel binary.  You should have your cross compiler
	all set for "arm-linux" target.

	make Image	(for the normal binary)
or	make zImage	(for the compressed image)

The following steps are very similar to the instructions provided by the
Itsy team for the original Brutus distribution
(http://www.research.digital.com/wrl/itsy/linux/linux-distrib-notes).

Step 6: You need angelboot to load the kernel and a ramdisk image.  A
	version of angelboot is provided in angelboot.tgz where you found
	this patch.
	
	tar -xzf angelboot.tgz
	cd angelboot
	make
	cd ..

Step 7: You need a ramdisk image. You may use the one provided with the
	original Brutus Linux distribution. The image used is specified as
	"otherfile" in the opts file from the angelboot.tgz archive.
	The file can be gzipped.  It will be loaded along with the kernel
	image in the next step.

Step 8:	Load and start the kernel.  I provided the "go" script in the 
	angelboot.tgz archive which makes use of angelboot with the 
	right options for the 2.0.35 patch.  These options are NOT 
	working with the 2.2.x patches.
	The following points are important:

	load=0xc0008000
	entry=0xc0008000

	and the linux/arch/arm/boot/Image file must be used from
	the "go" script file.  Dont use vmlinux or such.


That's it!

Have fun!
