The DP83867 has a muxing option for the CLK_OUT pin. It is possible
to set CLK_OUT for different channels.
Create a binding to select a specific clock for CLK_OUT pin.
Based on commit 9708fb630d19 ("net: phy: dp83867: Add binding for
the CLK_OUT pin muxing option") of mainline linux kernel.

There are VLAN related macros defined in include/linux/if_vlan.h
in Linux kernel, as well as some kernel useful structures and inline
functions. Instead of a complete import from kernel, let's add these
VLAN macros to U-Boot's include/linux/if_ether.h.

There are plenty of existing drivers that have macros like ETH_ALEN
defined in their own source files. Now that we imported the kernel's
if_ether.h to U-Boot we can reduce some duplication.

This imports include/uapi/linux/if_ether.h from Linux kernel v4.17.
It can be very helpful When porting Linux ethernet driver to U-Boot.
Note it is not exactly the same as the kernel one, as checkpatch
issues are fixed.

Rather than passing a hardcoded maxsize to the generic get_ram_size()
function use the i.MX 7 specific imx_ddr_size() function, which extracts
the memory size at runtime by reading the DDR controller registers.
This is a purely cosmetic change as the generic get_ram_size() function
already took care of properly automatically detecting 256MB, 512MB or 1GB
modules.

This file has changed quite a bit in the last 5 years as the capabilities
of the ECs have grown. Sync it up with the copy in coreboot commit
b9141f2215.
The only change is the addition of EC_VBNV_BLOCK_SIZE_V2. This is needed
because U-Boot uses the new v2 vboot API and this is not currently fully
supported by Chromium OS firmware.

At present sandbox sets non-blocking I/O as soon as any input is read
from the terminal. However it does not restore the previous state on
exit. Fix this and drop the old os_read_no_block() function.
This means that we always enable blocking I/O in sandbox (if input is a
terminal) whereas previously it would only happen on the first call to
tstc() or getc(). However, the difference is likely not important.

At present there are many situations where sandbox syncs the display to
the SDL frame buffer. This is a very expensive operation but is only
needed every now and then. Update video_sync() so that we can specify
whether this operation is really needed.
At present this flag is not used on other architectures. It could also
be used for reducing writeback-cache flushes but the benefit of that would
need to be investigated.

At present to output a log message you need something like:
log(UCLASS_SPI, LOCL_INFO, "message1");
log(UCLASS_SPI, LOCL_INFO, "message2");
but many files use the same category throughout. Also it is helpful to
shorten the length of log names, providing helpers for common logging
levels. Add some macros so that it is possible to do:
(top of file, before #includes)
#define LOG_CATEGORY UCLASS_SPI
(later in the file)
log_info("message1");
log_debug("message2");
log_err("message3");

On my Ubuntu 18.04.1 machine two driver-model bus tests have started

Adds a uclass to interface with a TEE (Trusted Execution Environment).
A TEE driver is a driver that interfaces with a trusted OS running in
some secure environment, for example, TrustZone on ARM cpus, or a
separate secure co-processor etc.
The TEE subsystem can serve a TEE driver for a Global Platform compliant
TEE, but it's not limited to only Global Platform TEEs.
The over all design is based on the TEE subsystem in the Linux kernel,
tailored for U-Boot.
