This driver actually does nothing but test pinctrl uclass, and
demonstrate how things work.
To try this driver, uncomment /* #define DEBUG */ in the
drivers/pinctrl/pinctrl-sandbox.c, and debug messages will be
displayed.

This creates a new framework for handling of pin control devices,
i.e. devices that control different aspects of package pins.
This uclass handles pinmuxing and pin configuration; pinmuxing
controls switching among silicon blocks that share certain physical
pins, pin configuration handles electronic properties such as pin-
biasing, load capacitance etc.
This framework can support the same device tree bindings, but if you
do not need full interface support, you can disable some features to
reduce memory foot print. Typically around 1.5KB is necessary to
include full-featured uclass support on ARM board (CONFIG_PINCTRL +
CONFIG_PINCTRL_FULL + CONFIG_PINCTRL_GENERIC + CONFIG_PINCTRL_PINMUX),
for example.
We are often limited on code size for SPL. Besides, we still have
many boards that do not support device tree configuration. The full
pinctrl, which requires OF_CONTROL, does not make sense for those
boards. So, this framework also has a Do-It-Yourself (let's say
simple pinctrl) interface. With CONFIG_PINCTRL_FULL disabled, the
uclass itself provides no systematic mechanism for identifying the
peripheral device, applying pinctrl settings, etc. They must be
done in each low-level driver. In return, you can save much memory
footprint and it might be useful especially for SPL.

Add a new uclass for TPMs which uses almost the same TIS (TPM Interface
Specification) as is currently implemented. Since init() is handled by the
normal driver model probe() method, we don't need to implement that. Also
rename the transfer method to xfer() which is a less clumbsy name.
Once all drivers and users are converted to driver model we can remove the
old code.

The current Infineon I2C TPM driver is written in two parts, intended to
support use with other I2C devices. However we don't have any users and the
Atmel I2C TPM device does not use this file.
We should simplify this and remove the unused abstration. As a first step,
move the code into one file.
Also the name tpm_private.h suggests that the header file is generic to all
TPMs but it is not. Rename it indicate that it relates only to this driver

Since commit 2580a2a7e719 ("mtd: nand: Increase max sizes of OOB and
Page size"), three boards (ph1_ld4, ph1_pro4, ph1_sld8) fail to build
with the following error message:
arm-linux-gnueabi-ld.bfd: SPL image plus BSS too big
They compile drivers/mtd/nand/denali_spl.c and it has a page_buffer
as static data:
static uint8_t page_buffer[NAND_MAX_PAGESIZE];
This buffer required 8KB in .bss section before that commit and now
it has been increased to 16KB. Given limited code/memory size for SPL,
it is not a good idea to allocate a page buffer statically. In the
first place, the load address 'dst' can be used as a page buffer.

The device might have already been probed during the call to
device_probe() on its parent device (e.g. PCI bridge devices).
In its parent device's probe routine, it might probe all of
its child devices via device_probe() thus the codes reenter
device_probe_child(). To support code reentrancy, test these
allocated memory against NULL to avoid memory leak, and return
to the caller if dev->flags has DM_FLAG_ACTIVATED set after
device_probe() returns, so that we don't mess up the device.

So far if CONFIG_VGA_AS_SINGLE_DEVICE is not defined, the VGA device
will try to initialize a keyboard device (for x86, it is i8042). But
if i8042 controller initialization fails (eg: there is no keyboard
connected to the PS/2 port), drv_video_init() just simply returns.
This kills the opportunity of using a usb keyboard later with the vga
console, as the vga initialization part is actually ok, only keyboard
part fails. Change the code logic to allow this.

The existing i8042 keyboard controller driver has some issues.
First of all, it does not issue a self-test command (0xaa) to the
controller at the very beginning. Without this, the controller
does not respond to any command at all. Secondly, it initializes
the configuration byte register to turn on the keyboard's interrupt,
as U-Boot does not normally allow interrupts to be processed.
Finally, at the end of the initialization routine, it wrongly
sets the controller to disable all interfaces including both
keyboard and mouse.

Per Intel FSP specification, we should call FSP notify API to
inform FSP that PCI enumeration has been done so that FSP will
do any necessary initialization as required by the chipset's
BIOS Writer's Guide (BWG).
Unfortunately we have to put this call here as with driver model,
the enumeration is all done on a lazy basis as needed, so until
something is touched on PCI it won't happen.
Note we only call this after U-Boot is relocated and root bus has
finished probing.
