The goal of this driver is consolidate information about SuperIO chips
and to provide for peaceful coexistence of drivers that need to access
SuperIO configuration registers.
While SuperIO chips can host various functions most of them are
discoverable and accessible without any knowledge of the SuperIO.
Examples are: keyboard and mouse controllers, UARTs, floppy disk
controllers. SuperIO-s also provide non-standard functions such as
GPIO, watchdog timers and hardware monitoring. Such functions do
require drivers with a knowledge of a specific SuperIO.
At this time the driver supports a number of ITE and Nuvoton (fka
Winbond) SuperIO chips.
There is a single driver for all devices. So, I have not done the usual
split between the hardware driver and the bus functionality. Although,
superio does act as a bus for devices that represent known non-standard
functions of a SuperIO chip. The bus provides enumeration of child
devices based on the hardcoded knowledge of such functions. The
knowledge as extracted from datasheets and other drivers.
As there is a single driver, I have not defined a kobj interface for it.
So, its interface is currently made of simple functions.
I think that we can the flexibility (and complications) when we actually
need it.
I am planning to convert nctgpio and wbwd to superio bus very soon.
Also, I am working on itwd driver (watchdog in ITE SuperIO-s).
Additionally, there is ithwm driver based on the reverted sensors
import, but I am not sure how to integrate it given that we still lack
any sensors interface.

NANDFS has been broken for years. Remove it. The NAND drivers that
remain are for ancient parts that are no longer relevant. They are
polled, have terrible performance and just for ancient arm
hardware. NAND parts have evolved significantly from this early work
and little to none of it would be relevant should someone need to
update to support raw nand. This code has been off by default for
years and has violated the vnode protocol leading to panics since it
was committed.

Add a CAM-Newbus SDIO support module. This works provides a newbus
infrastructure for device drivers wanting to use SDIO. On the lower end
while it is connected by newbus to SDHCI, it talks CAM using the MMCCAM

This also duplicates the usbdevs framework to equally create sdiodev

FDT data is sometimes used to configure usb devices which are hardwired into
an embedded system. Because the devices are instantiated by the usb
enumeration process rather than by ofwbus iterating through the fdt data, it
is somewhat difficult for a usb driver to locate fdt data that belongs to
it. In the past, various ad-hoc methods have been used, which can lead to
errors such applying configuration that should apply only to a hardwired
device onto a similar device attached by the user at runtime. For example,
if the user adds an ethernet device that uses the same driver as the builtin
ethernet, both devices might end up with the same MAC address.
These changes add a new usb_fdt_get_node() helper function that a driver can
use to locate FDT data that belongs to a single unique instance of the
device. This function locates the proper FDT data using the mechanism
detailed in the standard "usb-device.txt" binding document [1].
There is also a new usb_fdt_get_mac_addr() function, used to retrieve the
mac address for a given device instance from the fdt data. It uses
usb_fdt_get_node() to locate the right node in the FDT data, and attempts to
obtain the mac-address or local-mac-address property (in that order, the
same as linux does it).
The existing if_smsc driver is modified to use the new functions, both as an
example and for testing the new functions. Rpi and rpi2 boards use this
driver and provide the mac address via the fdt data.

- Make lindebugfs depend on linuxkpi (for seq_file)
- Check if read/write functions are set before calling, DRM drivers

modules outside of a kernel and such modules never match real cofigured
kernel.
So, we should prevent our users from building obviously defective modules.
Therefore, remove the root cause of the building of modules outside of a
kernel - the possibility of building modules with DEBUG or KTR flags.
And remove all of DEBUG printfs as it is incomplete and in threaded
programms not informative, also a half of system call does not have DEBUG
printf. For debuging Linux programms we have dtrace, ktr and ktrace ability.

That's the minimum 3 of copyin/copyout operations for one syscall.
Also some syscall uses linux_sa_put() and linux_getsockaddr() when load
sockaddr to userspace or from userspace accordingly.
To avoid this chaos, especially converting sockaddr in the userspace,
rewrite these 4 functions to convert sockaddr only in kernel and leave
only 2 of this functions.
Also in order to reduce duplication between MD parts of the Linuxulator put
struct sockaddr conversion functions that are MI out into linux_common module.
