The timing information on a 16 or 20 Mhz MC68020 are in the file
c/src/lib/libbsp/m68k/mvme135/times.  This is the output of the
RTEMS Timeing Tests.

Works or you can use another target and run on a CPU simulator
built into gdb such as sis for the sparc (erc32 BSP) or psim
for the powerpc (psim BSP).

This was/is? the site of the crossgcc archive.  What were you looking for?
