took a look, it's very straightforward, and clear.

unfortunately the chsnge  of the ls180 signal named "sys_clk" has
knock-on implications, aboit 8 different code locations are needed in
several separate repositories, in the coriolis2 settings, pinouts, and
so on.

it would be much less work for both myself and Jean-Paul if the rename
was done such that sys_clk remains the same in ls180.

is that practical / possible?  if not we can probably luve with it.
