It's not that simple. Take the gearbox for example. You say bunch of
MDIO registers. ASIC FW has a custom SDK internally that is used to
talk to the gearbox.
The flash, you say expose by MTD, but there is no access to it directly
from host. Can't be done. There are HW design limitations that are
blocking your concept.
