I understand. But I work with a very nice operating system that has
never had a need for __asm__, so I question the need for it myself.

I'd still like to see the reason that memset is so slow.

Also, I realize we have dropped support for other architectures, but
coreboot is still in principle portable. This change will be the
beginning of the removal of the portability. Before we start to make
such a change we need to make a conscious decision that losing
portability is what we want.

Part of "portability", in this case, is eventually moving to native
64-bit mode for the x86_64. I think we'll have to do that when we have
machines with more memory than PAE can address.

thanks

ron
