- Flesh out ofw_readin routine. - Add OpenFirmware load and exec routines. - Make sure memory allocation for the kernel is done correctly. - Change the way the heap is allocated so as to make it easier to deallocate when we hand over. - Add a command to print memory maps similar to the one for ia64. With this patch, I can now load and hand over to a kernel on my iMac. There are some problems with OpenFirmware routines failing after the hand over that still need to be addressed.
