MacOnLinux on a NON-OF machine

[Ross Vumbaca]

Hi,

I am working with the new AmigaOne board in porting Linux to it.

In the past MOL was successfully run on the AmigaOne.

The AmigaOne has since changed - the firmware is now an enanced version 
of the open source ppcboot, and is not an "Open Firmware" firmware.

I found that I couldn't get the kernel module mol.o to load. This was 
due to the "find_path_device" function no longer being present in the 
AmigaOne's Linux kernel. Unless I'm mistaken, that function returns the 
root to the OF Device Tree - and since the AmigaOne is not an OF machine 
anymore, there is no OF Device Tree.

I hacked the module so that that function call is not being made, and a 
0 is returned instead of a device tree root.

I then got MOL set up, but when I run it I find it does nothing, it 
loads and exits mysteriously. Assumedly my little hack broke MOL (as I 
expected).

My question is - is MOL reliant on this device tree for the emulated 
Mac? Would I be correct in saying that MOL does not emulate OF, and in 
fact uses the host machines OF Tree to provide the emualated Mac with an 
OF Tree? (Or am I wrong?).

Any comments or criticisms appreciated.. :)

Regards,

Ross..
