make use of it where possible.
This primarily brings in support for newer hardware, and FreeBSD is not yet
able to support the abundance of IRQs on new hardware and many features in the
Ethernet driver.
Because of the changes to IRQs in the Simple Executive, we have to maintain our
own list of Octeon IRQs now, which probably can be pared-down and be specific
to the CIU interrupt unit soon, and when other interrupt mechanisms are added
they can maintain their own definitions.
Remove unmasking of interrupts from within the UART device now that the
function used is no longer present in the Simple Executive. The unmasking
seems to have been gratuitous as this is more properly handled by the buses
above the UART device, and seems to work on that basis.
facilities as well as support for the Octeon 2 family of SoCs.
XXX Note that with our antediluvian assembler, we can't support some Octeon 2
instructions and fall back to using the old ones instead.
Executive is a library that can be used by standalone applications and kernels
to abstract access to Octeon SoC and board-specific hardware and facilities.
The FreeBSD port to Octeon will be updated to use this where possible.
