[Qemu-devel] Sparc system emulator updates

[Blue Swirl]

Hi,

New since last patch:
* Loader for a.out format binaries. Now we can try loading almost any kernel 
or boot loader in sight. I tried as many as I found. None worked.
* Floppy drive and controller are mutated PC ones.
* Serial ports, mouse, keyboard stubs.
* Changed IRQ definition from PIL levels to interrupt controller's register 
bit numbers.
* MMU probe operations implemented, Linux and OpenBSD use them.
* Added MMU table dump function for debugging.
* Unimplemented quad FP ops should trap. No known real CPUs implement them, 
why should we?
* If FPU is disabled, all FP ops trap.
* Added synthetic op optimisations.
* Other tweaks, cleanup.

Since last week, Linux advanced from poke_srmmu() call to next C line. At 
this rate, we'll reach userland somewhere near year 2050.
