There are dumps after all, here. These are from CP31 CPU board (68030@33 Mhz + 68882). Quick memory map:

68230 PIT $FF800C00
68561 MPCC $FF800000
62421 RTC $FF800A00
68230 PIT2 $FF800200
32KB 0ws SRAM $FF04xxxx..$FF07xxxx
256KB EPROM $FF00xxxx..$FF03xxxx

CP31 manual says that ROM is initially mapped at 0, and the mapping is reset by writing anything to this address.
