In RS485 mode RTS line acts as a transceiver direction control.
The datasheet is not very clear about the polarity but register setting
here is tested to drive nRTS line high when transmitting.
Also note revision of B of the super-IO has errata and 8N1 setting does
not work properly, you would need revision C of the chip assembled to
fix this.

b. Accept a callback function to add any device specific information to

This version of coreboot successfully starts a Harvey (Plan 9) kernel as a payload,
entering main() with no supporting assembly code for startup. The Harvey port
is not complete so it just panics but ... it gets started.
We provide a standard payload function that takes a pointer argument
and makes the jump from machine to supervisor mode;
the days of kernels running in machine mode are over.
We do some small tweaks to the virtual memory code. We temporarily
disable two functions that won't work on some targets as register
numbers changed between 1.7 and 1.9. Once lowrisc catches up
we'll reenable them.
We add the PAGETABLES to the memlayout.ld and use _pagetables in the virtual
memory setup code.
We now use the _stack and _estack from memlayout so we know where things are.
As time goes on maybe we can kill all the magic numbers.
