it has to be a valid ELF image (use vmlinux)

i have been able to boot a kernel via hpcboot and to launch a
shell. various people have been asking for a description off list, so i
made a page documenting it:
http://acid.ch.pw.edu.pl/~sq5bpf/mylinux/linux-jornada720/

a short summary is:
- comment out the architecture check in arch/arm/kernel/head-armv.S
- don't use the framebuffer - it hangs the kernel (at least in
2.4.18-rmk2-hh2), use the serial console
- if you don't have anything to boot from (like a CF card) hack the kernel
to include a filesystem and load it to ramdisk at boot time (see
CONFIG_BLK_DEV_CIBD in the kernel you can download from my page - this is
more of a dirty hack than a solution but it works). it would be nice for
hpcboot to support initrd

a description and a working kernel that boots and gives a shell on the
serial port is included.
