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.
o) Add 'octm', a trivial driver for the 10/100 management ports found on some
Octeon systems.
o) Make the Simple Executive's management port helper routines compile on
FreeBSD (namely by not doing math on void pointers.)
o) Add a cvmx_mgmt_port_sendm routine to the Simple Executive to send an mbuf
so there is only one copy in the transmit path, rather than having to first
copy the mbuf to an intermediate buffer and then copy that to the Simple
Executive's transmit ring.
o) Properly work out MII addresses of management ports on the Lanner MR-730.
XXX The MR-730 also needs some patches to the MII read/write routines, but
this is sufficient for now. Media detection will be fixed in the future
when I can spend more time reading the vendor-supplied patches.
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.
