Aleksey Makarov fd7ec06254 net: thunderx: add static
This fixes sparse messages like this:

drivers/net/ethernet/cavium/thunder/nicvf_main.c:1141:26: sparse: symbol
'nicvf_get_stats64' was not declared. Should it be static?

Also remove unused declarations

Robert Richter d768b678a8 net: thunderx: Cleanup duplicate NODE_ID macros, add nic_get_node_id()
There are duplicate NODE_ID macro definitions. Move all of them to
nic.h for usage in nic and bgx driver and introduce nic_get_node_id()
helper function.

This patch also fixes 64bit mask which should have been ULL by
reworking the node calculation.

Arnd Bergmann 5e9615bfb9 net: thunderx: add 64-bit dependency
The thunderx ethernet driver fails to build on architectures
that do not have an atomic readq() and writeq() function for
64-bit PCI bus access:

drivers/net/ethernet/cavium/thunder/thunder_bgx.c: In function 'bgx_reg_read':
include/asm-generic/io.h:195:23: error: implicit declaration of function 'readq' [-Werror=implicit-function-declaration]

It seems impossible to get this driver to work on most 32-bit
hardware, so it's better to add an explicit dependency, in
order to let us keep building 'allmodconfig' kernels on
all architectures.

As the driver is meant for the internal hardware on an arm64 SoC, this
is not a problem for usability. Allowing the build on all 64-bit
architectures rather than just CONFIG_ARM64 on the other hand means that
we get the benefit of build testing on x86.

Sunil Goutham 4863dea3fa net: Adding support for Cavium ThunderX network controller
This patch adds support for the Cavium ThunderX network controller.
The driver is on the pci bus and thus requires the Thunder PCIe host
controller driver to be enabled.
