Look at how piggy.o is built in arch/arm/boot/compressed/Makefile. You
can also make ld do the same -- check out arch/arm/boot/bootp/Makefile.

It can be used for network booting if your bootloader can speak bootp.
But that's not why it is useful in this case. The bootp support is
simply a kernel and an initrd in a single image, along with the right
magic to tell the kernel where to find the initrd. Standard Linux
stuff comes next -- the initrd needs to have whatever drivers and user
tools are required to find and mount the root parition. That probably
means pcmcia+ide-cs+ide-disk+yadda yadda. Once the initrd runs, it
should pivot_root (or the like) to a proper root file system, found on
CF.

I had this running at one time on my 720, long ago.
