U-Boot already supports using -D to indicate that it should use the normal
device tree. It is sometimes useful to run with the test device tree, e.g.
when running a test. Add a -T option for this along with some
documentation.
It can be used like this:
/tmp/b/sandbox/u-boot -T -c "ut dm pci_busdev"
(this will use /tmp/b/sandbox/arch/sandbox/dts/test.dtb as the DT)

At present this function is never called when of-platdata is enabled since
we never have a device tree. However, this function is responsible for
copying over the of-platdata, so we must call it. Otherwise the probe()
method would have to be used.
Correct this and fix the sandbox serial driver to not read from the device
tree and try to write to what is read-only platdata on some platforms.

At present when multiple 'ut dm' commands are executed, all but the first
is run with a flat tree, even if live tree is enabled. This is because the
live tree node pointer is set to NULL and never restored.
This does not affect normal test running, which just runs all the test in
one go, but can be confusing when several individual tests are run during
the same U-Boot run.
Correct this by restoring the pointer.

At present we assume that CAR (Cache-as-RAM) is used if HOBs (Hand-off
blocks) are not, since HOBs typically indicate that an FSP is in use, and
FSPs handle the CAR init.
However this is a bit indirect, and for FSP2 machines which use their own
CAR implementation (such as apollolake) but use the FSP for other
functions, the logic is wrong.
To fix this, add a dedicated Kconfig option to indicate when CAR is used.

The useable RAM is calculated when the RAM is inited. Save this value so
that it can be easily used in U-Boot proper.
Also save a pointer to the hob list so that it is accessible (before
relocation only) in U-Boot proper. This avoids having to scan it in SPL,
for everything U-Boot proper might need later.

U-Boot is built in three phases: TPL, SPL and U-Boot proper. Sometimes
it is necessary to use different init code depending on the phase. For
example, TPL might do very basic CPU init, SPL might do a little more

cores.

At present the bloblist is set up in spl_common_init() which can be called
from spl_early_init(), i.e. before SDRAM is ready. This prevents the
bloblist from being located in SDRAM, which is useful on some platforms
where SRAM is inaccessible after U-Boot relocates (e.g. x86 CAR region).
It doesn't serve much purpose to have the bloblist available early, since
very little is known about the platform then, and the handoff info is
written when SPL is about to jump to U-Boot.
Move the code to board_init_r() to avoid any restrictions.
