[Uwe Hermann]

See patch.

Build-tested, but not yet run-time-tested on any board.

Uwe.

As you know I'd rather see this done differently but I need to put the
select MMX
in all those CPUs that support it. So I will change this later when I
can, or someone else can. Here's what it ought to look like:

+crt0-$(CONFIG_CPU_AMD_GX1) += ../../../../src/cpu/amd/model_gx1/cpu_setup.inc
+crt0-$(CONFIG_CPU_AMD_GX1) += ../../../../src/cpu/amd/model_gx1/gx_setup.inc
 crt0-$(CONFIG_MMX) += ../../../../src/cpu/x86/mmx/enable_mmx.inc
 crt0-$(CONFIG_SSE) += ../../../../src/cpu/x86/sse/enable_sse.inc
 crt0-y += auto.inc
 crt0-$(CONFIG_SSE) += ../../../../src/cpu/x86/sse/enable_sse.inc
 crt0-$(CONFIG_MMX) += ../../../../src/cpu/x86/mmx/disable_mmx.inc

But, as said,for each CPU that supports SSE and MMX, we have to add
the right select statements.

But this is such fine work that it is:

Sure, we'll change that as soon as the SSE/MMX infrastructure is in
place.

Thanks, r4719.

BTW, what are the rules for MMX/SSE? IIRC MMX was in Ppro. What
supported CPUs can we assume support MMX and SSE? Can we go by socket
type (likely on newer parts) or do we have to go by model/family?

MMX was introduced on the Pentium. There was Pentium, then came
Pentium-MMX. It took a while, so Pentium Pro might have been there
before Pentium-MMX. My guess is that Pentium Pro did not have MMX.

SSE came in Pentium III.

The Pentiums are tricky with MMX, because the same board will run
just fine with Pentium and Pentium-MMX alike. So for Pentium boards
it's not really safe to assume there will ever be MMX.

The later models were slot 1 or socket 370. Could you put a standard
Pentium in a socket 370? I doubt it. Then it's safe to set MMX based
on socket.

What about Pentium III? IIRC you could put an FCPGA Pentium III in an
adapter that made it into a slot 1, and could run instead of a
Pentium II.. Can't rely on the socket there.
