In U-boot, serial_tstc was use to determine is there have a character in
serial console that pending for read. If there is no "pending" function
implemented in serial driver, the serial-uclass will return "true(1)"
to indicate there have a character pending to read.
Thus, read a character from nulldev serial will result in continuous
getting -EAGAIN return which might lead system to hang.
This commit is to fix a bug in nulldev serial which implement "pending"
function in nulldev serial to always indicate there is no character in
console that pending for read.

This is required in the case where U-Boot is typically loaded and run at
a particular address, but for some reason the RAM at that location is not
available, e.g. due to memory fragmentation loading other boot binaries or
firmware, splitting an SMP complex between various different OSs without
using e.g. the EL2 second-stage page tables to hide the memory asignments,
or due to known ECC failures.

It can be useful to record how long tests take; this can help debug slow
running test systems or track changes in performance over time. Enhance
the test system to record timestamps while running test:
- Whenever a new log file section is started.
- After U-Boot is started and communication has been established.
- After each host or U-Boot command is executed.

Currently, pylibfdt is always compiled if swig is installed on your
machine. It is really annoying because most of targets (excepts
x86, sunxi, rockchip) do not use dtoc or binman.
"checkbinman" and "checkdtoc" are wrong. It is odd that the final
build stage checks if we have built necessary tools. If your platform
depends on dtoc/binman, you must be able to build pylibfdt. If swig
is not installed, it should fail immediately.
I added PYLIBFDT, DTOC, BINMAN entries to Kconfig. They should be
property select:ed by platforms that need them. Kbuild will descend
into scripts/dtc/pylibfdt/ only when CONFIG_PYLIBFDT is enabled.

The pylibfdt is used by dtoc (and, indirectly by binman), but there
is no reason why it must be generated in the tools/ directory.
Recently, U-Boot switched over to the bundled DTC, and the directory
structure under scripts/dtc/ now mirrors the upstream DTC project.
So, scripts/dtc/pylibfdt is the best location.
I also rewrote the Makefile in a cleaner Kbuild style.
The scripts from the upstream have been moved as follows:
lib/libfdt/pylibfdt/setup.py -> scripts/dtc/pylibfdt/setup.py
lib/libfdt/pylibfdt/libfdt.i -> scripts/dtc/pylibfdt/libfdt.i_shipped
The .i_shipped is coped to .i during building because the .i must be
located in the objtree when we build it out of tree.

function "fdt_prop_parse" runs into troubles upon it wants to write some

To avoid this we tell the compiler to always align this scratchpad to a
