Add the "/reserved-memory/optee" node to the SPL devicetree. The
purpose is to allow configuring TZC regions when booting OP-TEE.

OP-TEE is very particular about how the TZC should be configured.
When booting an OP-TEE payload, an incorrect TZC configuration will
result in a panic.
Most information can be derived from the SPL devicetree. The only
information we don't have is the split between TZDRAM and shared
memory. This has to be hardcoded. The rest of the configuration is
fairly easy, and only requires 3 TZC regions. Configure them.
Signed-off-by: Alexandru Gagniuc <mr.nuke.me@gmail.com>
The purpose of this change is to allow configuring TrustZone (TZC)
memory permissions. For example, OP-TEE expects TZC regions to be
configured in a very particular way. The API presented here is
intended to allow exactly that.
UCLASS support is not implemented, because it would not be too useful.
Changing TZC permissions needs to be done with care, so as not to cut
off access to memory we are currently using. One place where we can
use this is at the end of SPL, right before jumping to OP-TEE.

OP-TEE requires some particular setup, which is not needed for linux
or other payloads. Add a hook for platform-specific code to perform
any OP-TEE related configuration and initialization.
A weak function is used because it is symmetrical to other
spl_board_prepare_for_*() implementations. A solution to avoid the use
of weak functions would trivially apply to all these implementations.
However, re-designing this is beyond the scope of this patch.

In general, Falcon mode means we're booting a linux kernel directly.
With FIT images, however, an OP-TEE secure kernel can be booted before
linux. Thus, if the next stage is an IH_OS_TEE, this isn't necessarily
a problem.
Of course, a general solution would involve mmc_load_image_raw_os()
only loading the binary, and leaving the decision of suitability to
someone else. However, a rework of the boot flow is beyond the scope
of this patch. Accept IH_OS_TEE as a valid OS value.

When a push-button is released and PA13/PA14 are defined as input (high-Z)
the LED should not be active as the circuit is open but a small current
leak through PCB or push-button close the circuit and allows a small LED
bias giving erroneous level voltage.
So it is recommended to activate an internal pull-up in order to clearly
fix the voltage at PA13/PA14 when button is released and to wait
a short delay before to read the GPIO value only when the pull-up is

Add a Sierra PHY driver with PCIe and USB support.
This driver is a port from the mainline linux driver.
The PHY has multiple lanes, which can be configured into
groups, and a generic PHY device is created for each group.
There are two resets controlling the overall PHY block, one
to enable the APB interface for programming registers, and
another to enable the PHY itself. Additionally there are
resets for each PHY lane.
The PHY can be configured in hardware to read register
settings from ROM, or they can be written by the driver.
The sequence of operation on startup is to enable the APB
bus, write the PHY registers (if required) for each lane
group, and then enable the PHY. Each group of lanes
can then be individually controlled using the power_on()/
power_off() function for that generic PHY
One difference with the linux driver is that the PHY is
always reset after it is powered-on. This is because role
switching is not supported in u-boot and the cable
orientation is handled by the PHY reset.
