Other platforms may provide similar support, but they do that

with the current assumptions, but it also allows one to
differentiate a platform desiring SPI flash support while it not
being the actual boot device.
One thing to note is that while google/daisy does boot with SPI

Until now it was assumed that all TPM devices were of the same type
(TCG 1.2 spec compliant) and x86 based boards had LPC connected TPMs
and all other boards had I2C connected TPMs.
With the advent of TPM2 specification there is a need to be able to
configure different combinations of TPM types (TPM or TPM2) and
interfaces (LPC, I2C and SPI).
This patch allows to do it. Picking Chrome OS still assumes that the
board has a TPM device, but adding MAINBOARD_HAS_TPM2 to the board's
Kconfig will trigger including of TPM2 instead.
MAINBOARD_HAS_LPC_TPM forces the interface to be set to LPC, adding
SPI_TPM to the board config switches interface choice to SPI, and if
neither of the two is defined, the interface is assumed to be I2C.

On modern x86 platforms like apollolake, pre-RAM stages verstage and
romstage run within the cache-as-ram region. Thus, we do not need to
pass in the --xip parameter to cbfstool while adding these
stages. Introduce a new Kconfig variable NO_XIP_EARLY_STAGES which is
default false for all x86 platforms. Apollolake selects this option
since it supports code execution with CAR.

Instead of hard coding a #define in each architecture's
tables.c for the coreboot table size in cbmem use a Kconfig
varible. This aids in aligning on a common write_tables()
implementation instead of duplicating the code for each
architecture.

Reorder drivers to fit src/drivers/[X]/[Y]/ scheme to make
them pluggable.
Also, fix up the following driver subdirectories by switching
to the src/drivers/[X]/[Y]/ scheme as these are hard requirements
for the main change:
* drivers/intel
* drivers/pc80
* drivers/dec

Instead of just defaulting to disabled, remove the option for
x86 since it doesn't work there.

This patch ports the LZ4 decompression code that debuted in libpayload
last year to coreboot for use in CBFS stages (upgrading the base
algorithm to LZ4's dev branch to access the new in-place decompression
checks). This is especially useful for pre-RAM stages in constrained
SRAM-based systems, which previously could not be compressed due to
the size requirements of the LZMA scratchpad and bounce buffer. The
LZ4 algorithm offers a very lean decompressor function and in-place
decompression support to achieve roughly the same boot speed gains
(trading compression ratio for decompression time) with nearly no
memory overhead.
For now we only activate it for the stages that had previously not been
compressed at all on non-XIP (read: non-x86) boards. In the future we
may also consider replacing LZMA completely for certain boards, since
which algorithm wins out on boot speed depends on board-specific
parameters (architecture, processor speed, SPI transfer rate, etc.).
BRANCH=None
BUG=None
TEST=Built and booted Oak, Jerry, Nyan and Falco. Measured boot time on
Oak to be about ~20ms faster (cutting load times for affected stages
almost in half).

Add the DEBUG_BOOT_STATE Kconfig value to enable boot state debugging.
Update include/bootstate.h and lib/hardwaremain.c to honor this value.
Add a dashed line which displays between the states.
Testing on Galileo:
* select DEBUG_BOOT_STATE in mainboard/intel/galileo/Kconfig
* Build and run on Galileo
