Re: [Qemu-devel][PATCH]Get machine name from name of executable

[Fabrice Bellard <fabrice@bellard.org>]

I don't understand your problem : the '-M' option is used to select the 
machine. Your "ar7" machine must be added as a new machine. The 
endianness must be selected inside the machine code. If the machine can 
be launched with the two endiannesses, then you can just add two 
machines names.
