Re: [hatari-devel] 68030 MMU work

This should be corrected now. Obviously there is an error in the datasheet i'm using (M68000PRM.pdf). The instruction format for PTEST is wrong: register field should be 3 bit and FC field should be 5 bit.
I already discovered this when writing PTEST emulation, but obviously still used the wrong shift and a bad debugging output.

I've appended the patch to this message. The patch also cleans debugging messages for the mmu ops.
