clear_tpm_owner_request

The first one requests that the firmware clear the TPM owner on the
next boot. When the firmware does this, it will set
clear_tpm_owner_request=0, and set clear_tpm_owner_done=1. The OS can
use the done-flag as a hint that trusted things guarded by the TPM are

Presently kernel load address and buffer size are programmed in the
u-boot device tree. There is no reason for this: the address and size
are part of the vboot encapsulation headers. Duplicating this
information hardcoded in the device tree does not bring any benefit
and is in fact harmful, as it is easy to get out of sync.
A better way of doing things is to derive kernel load address and size
from the appropriate vboot header. ARM people object to this, as they
want the very same kernel blob operate on devices with DRAM mapped to
different address ranges.
The suggested solution is to exclude the kernel memory section from
the device tree on the platforms where the load address could be
safely taken from the vboot header. In this case u-boot will pass
address of zero to vboot, which will know to derive the address/size
from the appropriate header. vboot then rewrites fields of the u-boot
supplied structure with actual address and size of the kernel blob.
There is no sanity check yet, as it is presumed that there is enough
memory to load any kernel and u-boot does not use the space above
0x100000 for at least 16 megabytes (the kernel partition size). On x86
platform the check could be verify that the top of the kernel space is
well below the stack.

The important things are that the first number is now 2, instead of 1, and
the last number is not zero (it's a checksum, so it'll vary depending on the
other numbers, which will themselves vary according to the firmware and
kernel versions).

This macro is only defined by the EC firmware build process, and is used to
cut down the amount of compiled code. A future CL will refactor the library
to make this unnecessary.

Omit this check because this check is not really necessary and it is
dealing more harms than goods to ARM boards.
While body load address is configurable, it is not quite possible to fix
all the build scripts and runtime scripts to carry this address; so in
reality all scripts use the default body load address.
The problem is, this default address is not friendly to ARM boards, and
it virtually makes this check fails on ARM boards.

When the filesystem resizing process starts, it has the TPM open,
which means it can collide with tcsd after the main process exits.
Additionally, improve the debugging around TPM usage for better timing
analysis.

Due to the limitation of servo that is unable to send U keys, dev USB boot
(triggered by Ctrl-U) is unable to be tested on FAFT. To solve it, firmware
should add an addition key combination to workaround it. Ctrl-Enter is the
one we picked.
