The Tile architecture port was added by Chris Metcalf in 2010, and
maintained until early 2018 when he orphaned it due to his departure
from Mellanox, and nobody else stepped up to maintain it. The product
line is still around in the form of the BlueField SoC, but no longer
uses the Tile architecture.
There are also still products for sale with Tile-GX SoCs, notably the
Mikrotik CCR router family. The products all use old (linux-3.3) kernels
with lots of patches and won't be upgraded by their manufacturers. There
have been efforts to port both OpenWRT and Debian to these, but both
projects have stalled and are very unlikely to be continued in the future.
Given that we are reasonably sure that nobody is still using the port
with an upstream kernel any more, it seems better to remove it now while
the port is in a good shape than to let it bitrot for a few years first.

This driver is 64 bit only, and so this driver and device are ready
for 2038. This patch changes the driver to the new PHC and also
carries the timespec64 parameter on out to the gxio_mpipe_get-
set_timestamp functions, making explicit the fact that the tv_sec
field is 64 bits wide.
Not even compile tested.

The initial driver support was for a single mPIPE shim on the chip
(as is the case for the Gx36 hardware). The Gx72 chip has two mPIPE
shims, so we extend the driver to handle that case.

The TILE-Gx chip includes a packet-processing network engine called
mPIPE ("Multicore Programmable Intelligent Packet Engine"). This
change adds support for using the mPIPE engine from within the
kernel. The engine has more functionality than is exposed here,
but to keep the kernel code and binary simpler, this is a subset
of the full API designed to enable standard Linux networking only.
