On the 68LC040 software FPU emulation errata...

[yuhong]

For those who wonder when Motorola started producing 68LC040 processors without the errata that caused problems with software FPU emulation, here is the actual PCN right from Freescale:

Cool - thank you. It's good to have a link like that which people can find easily.

I'd also like to remind people here that NetBSD for m68040s with no FPU (no matter which mask) compiled with -msoft-float is available here:

ftp://ftp.mac68k.org/pub/NetBSD/5.0.2/mac68k-softfloat/

and binary pkgsrc packages, also compiled with -msoft-float, are available here:

ftp://ftp.mac68k.org/pub/pkgsrc/packages/NetBSD/m68k-softfloat/

The binary packages are being built on a 40 MHz Quadra 605 and are updated daily, so the list will continuously grow. Currently we're up to 238.
