All other architectures set NEW_PCIB in DEFAULTS, with arm being the one
remaining straggler that only sets it for GENERIC and TEGRA124.
ARMADA38X and ARMADAXP contain device pci but don't set NEW_PCIB,
however GENERIC claims to support them and as part of that NEW_PCIB
support was added to mv_pci, so these configs are most likely just
stale. Other than NOTES that just leaves ALPINE as the one kernel with
PCI support not covered by GENERIC, but al_pci is supported by arm64
which enables NEW_PCIB, and it's just a generic_pcie_fdt_driver with
some fixup code to deal with quirks so should support PCI_RES_BUS just
fine. Therefore it is believed that all in-tree kernel configs support
NEW_PCIB in reality, and so let's take a step towards removing all the
non-NEW_PCIB code by having it always-on everywhere.

Following the removal of general MIPS support, there's no longer a need
to have the AHB bus-frontend in place, which according to Linux sources
also isn't used with any non-MIPS SoCs. For simplicity, PCI bus support
is only made conditional on the main one again, i. e. device ath_pci is
removed, and built into the main module, i. e. if_ath_pci.ko obsoleted,
respectively.
Effectively, this reverts the following commits and associated changes:

NETLINK is going to replace rtsock and a number of other ioctl/sysctl interfaces.
In-base utilies such as route(8), netstat(8) and soon ifconfig(8)
are being converted to use netlink sockets as a transport between
kernel and userland.
In the current configuration, it still possible have the kernel
without NETLINK (`nooptions NETLINK`) and use the aforementioned
utilies by buidling the world with `WITHOUT_NETLINK` src.conf knob.
However, this approach does not cover the cases when person unintentionally
builds a custom kernel without netlink and tries to use the standard userland.
This change adds `option NETLINK` to the default options for each
architecture, fixing the custom kernel issue.
For arm, this change uses `std.armv6` and `std.armv7` (netlink already in)
instead of DEFAULTS.

This is a followup of 692e19cf51 (add netlink to GENERIC@amd64).
Netlink is a communication protocol defined in RFC 3549. It is async,
TLV-based protocol, providing 1-1 and 1-many communications between kernel
and userland. Netlink is currently used in Linux kernel to modify, read and
subscribe for nearly all networking states. Interface state, addresses, routes,
firewall, rules, fibs, etc, are controlled via Netlink.
Netlink support was added in D36002. It has got a number of improvements and
first customers since then:
* net/bird2 got netlink support, enabling route multipath in FreeBSD
* netlink-based devd notifications are being worked on ( D37574 ).
* linux(4) fully supports and depends on Netlink
Enabling Netlink in GENERIC targets two goals.
The first one is to provide stability for the third-party userland applications,
so they can rely on the fact that netlink always exists since 14.0 and potentially 13.2.
Loadable module makes life of the app delepers harder. For example, `net/bird2` can be
either build with netlink or rtsock support, but not both.
The second goal is to enable gradual conversion of the base userland tools
to use netlink(4) interfaces. Converting tools like netstat (D36529), route,
ifconfig one-by-one simplifies testing and addressing the feedback.
Othewise, switching all base to use netlink at once may be too big of a leap.

This adds support for the IPQ4018/IPQ4019 MDIO bus. This is used to
talk to external PHYs and switches. (There's an internal switch

This adds some very simple DWC3 glue for the IPQ4018/IPQ4019.
Other chipsets introduce reset line iteration, some further
clock line iteration and some customisations; I'll look at adding
those later.
This is enough to finally bring up USB 3.0 on my IPQ4018 ASUS
RT-58U router.
This adds the USB 2.0 and 3.0 PHY support for the IPQ4018/IPQ4019.
All it really needs to do is gate the relevant clocks on/off in the
right order with the right delays.
The Qualcomm TCSR is some top level glue between multiple IP blocks,
both for doing configuration of said IP blocks, some IPC between
them (mostly between multiple execution environments - eg trustzone
and non-TZ), and interrupt status bits for them.
However, for the IPQ4018/IPQ4019, it only is used as a small subset
of IP block configuration. As for what it actually gets used as
for other Qualcomm chipsets? Well, that'll have to wait.
It's a bit of a mess in linux and openwrt. See, every different
SoC support branch ends up with some different TCSR code for it.
So instead, I'm going to land a single TCSR driver that I'm going
to use for the IPQ4018/IPQ4019. When I add the next chipset, I'll
figure out how to organise things so there's a single TCSR driver
that works for multiple platforms.
The Qualcomm Universal Peripherals Engine (QUP) is a unified SPI and I2C
peripheral that ships with a variety of Qualcomm SoCs.
It supports three transfer modes - single PIO, block PIO and DMA.
This driver only supports the single PIO mode, which is enough to
bootstrap the rest of the SPI NAND/NOR support and means I can do
things like read the Wifi calibration data from NOR. It has some
hardware support code for the other transfer modes as well as
some support for split transfers (ie, transfers with no read or
write phase), but I haven't yet implemented those.
This driver is based on four sources - the linux driver, the u-boot
driver, some initial work done for APQ8064 by mmel@, and the APQ8064
Technical Reference Manual which is surprisingly free and open to
read. The linux and u-boot drivers approach a variety of things
completely differently, from how PIO is done, the hardware support
for re-ordering bytes in a transfer word and how the CS lines
are used.
Tested:
* IPQ4018, SPI to NAND/NOR flash, PIO only
Now that the clock drivers are in the tree, the cpufreq driver will
"just work".
Tested:
* IPQ4018, testing performance of dd from /dev/zero->/dev/null at
each frequency step.

NOTE: HEADS UP read the note below if your kernel config is not including GENERIC!!
This patch does a bit of cleanup on TCP congestion control modules. There were some rather
interesting surprises that one could get i.e. where you use a socket option to change
from one CC (say cc_cubic) to another CC (say cc_vegas) and you could in theory get
a memory failure and end up on cc_newreno. This is not what one would expect. The
new code fixes this by requiring a cc_data_sz() function so we can malloc with M_WAITOK
and pass in to the init function preallocated memory. The CC init is expected in this
case *not* to fail but if it does and a module does break the
"no fail with memory given" contract we do fall back to the CC that was in place at the time.
This also fixes up a set of common newreno utilities that can be shared amongst other
CC modules instead of the other CC modules reaching into newreno and executing
what they think is a "common and understood" function. Lets put these functions in
cc.c and that way we have a common place that is easily findable by future developers or
bug fixers. This also allows newreno to evolve and grow support for its features i.e. ABE
and HYSTART++ without having to dance through hoops for other CC modules, instead
both newreno and the other modules just call into the common functions if they desire
that behavior or roll there own if that makes more sense.
Note: This commit changes the kernel configuration!! If you are not using GENERIC in
some form you must add a CC module option (one of CC_NEWRENO, CC_VEGAS, CC_CUBIC,
CC_CDG, CC_CHD, CC_DCTCP, CC_HTCP, CC_HD). You can have more than one defined
as well if you desire. Note that if you create a kernel configuration that does not
define a congestion control module and includes INET or INET6 the kernel compile will
break. Also you need to define a default, generic adds 'options CC_DEFAULT=\"newreno\"
but you can specify any string that represents the name of the CC module (same names
that show up in the CC module list under net.inet.tcp.cc). If you fail to add the
options CC_DEFAULT in your kernel configuration the kernel build will also break.
