generic kernel on the simulator

generic kernel on the simulator

[Ian Wienand]

Hi,

Should a generic kernel be able to boot on the simulator?  The kernel
seems to build in machine vector information for the simulator, but
I'm not sure if the simulator simulates enough for the init routines
to discover this?

I think it would be useful to have that work because it would mean
that anyone with access to real hardware could test at least two very
different platforms with a generic kernel (namely Ski and the real
hardware).

I suspect we'll need to add some more fw emulation to make this really
work.  Actually, looking at acpi_get_sysname(), perhaps we just need
to change it so that if the rsdp cannot be found, we default to hpsim?
Without RSDP, real hardware won't be able to boot anyhow, so returning
"dig" makes little sense.
