I haven't posted it anywhere else because it's a hack to workaround a
Qemu problem: the 5208 apparently has support for separate supervisor
and userspace stack pointers (through two different registers), but
Qemu doesn't emulate that. So I think it's a flaw in Qemu emulation
rather than a kernel problem, but it was easier for now to workaround
it by just adding one "select COLDFIRE_SW_A7".

Ah, ok. I only put the dual stack pointer support in a year or 2 back.
And it is only supported on the more modern ColdFire's, guess the QEMU
support is for the simpler parts :-)

Well, either Qemu pretends to emulate a 5208 and it should support the
dual stack pointer thing, or it shouldn't pretend to emulate a 5208.

Am I correct in my understanding is that the 5208 hardware does support
dual stack pointers?

Best regards,

Thomas
