173d8f08e8 x86: Initialize SPI controller explicitly during PCH init
This ensures that SPI is ready when eventlog code is used.

x86 platforms which use eventlog invoke elog_clear() in GSMI and
elog_add_event_raw() when deciding the boot path based on ME status.
For the SMM case spi_init() is called during the finalize stage in
SMM setup. For the boot path case we can call spi_init() at the
beginning of BS_DEV_INIT and it will be ready to use when the boot
path is determined from the ME status.

3f1f565baf tegra124: clock: Enforce PLL constraints for VCO and CF
This patch adds some documentation to the additional PLL divisor
constraints on the intermediary VCO and CF values that we just found out
about. PLLC divisors for some oscillators had to be adjusted
accordingly.

It also adds a new clock_get_pll_input_khz() function to replace
clock_get_osc_khz() in cases where you want to factor in the built-in
predivider for 38.4 and 48 MHz oscillators.

200aa7c5b1 x86: Set BOOT_MEDIA_SPI_BUS
BOOT_MEDIA_SPI_BUS is a Kconfig variable used on some ARM-based
platforms to set up CBFS media. It turns out it can also be helpful
for setting up the eventlog which is intended to reside on the same
SPI flash as CBFS. Setting it for x86 will allow us to remove an
assumption about which SPI bus is used for this flash device.

Long term this can go away as we come up with a better abstraction
for the eventlog's backing store. This is only intended to help us
get from here to there.

00c423fb2c i2c: Replace the i2c API.
The new API is in use in depthcharge and is based around the "i2c_transfer"
function instead of i2c_read and i2c_write. The new function takes an array of
i2c_seg structures which represent each portion of the transfer after a start
bit and before the stop bit. If there's more than one segment, they're
seperated by repeated starts.

Some wrapper functions have also been added which make certain common
operations easy. These include reading or writing a byte from a register or
reading or writing a blob of raw data. The i2c device drivers generally use
these wrappers but can call the i2c_transfer function directly if the need
something different.

The tegra i2c driver was very similar to the one in depthcharge and was simple
to convert. The Exynos 5250 and 5420 drivers were ported from depthcharge and
replace the ones in coreboot. The Exynos 5420 driver was ported from the high
speed portion of the one in coreboot and was straightforward to port back. The
low speed portion and the Exynos 5250 drivers had been transplanted from U-Boot
and were replaced with the depthcharge implementation.

bf16ea915c Provide ability to integrate with QComm SBLs
Ipq8064 SBLs initialize the hardware to prepare it to run an arbitrary
user provided bootloader. The only bootloader requirements imposed by
the SBLs are that it is concatenated with the SBL chunks in the
bootprm AND it uses MBN encapsulation (mostly to specify the size and
load address).

This patch adds configuration options to specify the location of the
SBL blobs and to require MBN encapsulation of the bootblock.

6871aa3151 cbmem console: Make cbmem console usable on ARM.
The current CBMEM console implementation can work in two different ways, one
that requires CAR migration which doesn't make sense on ARM and will break the
build, and a second which assumes 0x600 is a valid memory address which can be
used to keep track of the current location of the console. Neither of those
work on ARM.

To get around that problem, this change adds yet another flavor of behavior
to the cbmem console driver where it assumes the console is in a fixed place
before RAM is initialized (bootblock and ROM stage) and in CBMEM afterwards
(RAM stage). More specifically, the location of the console is always fixed
in a particular stage, attempts to set it are ignored, it's only initialized
in the earliest stage it's enabled, and cbmem reinitialization and migration
is ignored in RAM stage.

We really need to rework all the twisted paths through this code and reduce
it to one implementation that makes sense and works in all the situations it
needs to without all the extra complexity.

BUG=None
TEST=Built and booted on nyan with other changes that enable the console.

On non-x86 systems, the location of the preram CBMEM console may not be in a
predictable place relative to other things in the linker script. That makes it
difficult to work with as its own section because the linker will complain if
you try to move backwards as it lays out memory. If the console header is
treated as an actual blob of memory which has to be put in the image, we'd
have to predict where to put it so that it isn't before something with a lower
address or after something with a higher address. Symbols, on the other hand,
can be defined arbitrarily.

164f7010a4 tegra124: A couple clock fixes.
This fixes two problems with the clock configuration on tegra124. First, the
macro which set up the i2c clocks tried to account for the fact that the i2c
divisor's lsb represents 1.0 where it normally represents 0.5 by multiplying
the target frequency by 2. That doesn't work, unfortunately, because the
divisor is actually n + 1, and what n + 1 means depends on where the one's
place is in the divisor.

Also, when calculating the divisor, the standard C division operator uses
truncation to deal any remainder which tends to make the divisor smaller. That
has the effect of making the output frequency higher than what was requested.
Since it's usually safer to undershoot a frequency than overshoot it, this
change makes those divisions round up instead.

Finally, the hand tuned temporary UART clock configuration was adjusted so
that it still ends up with the same divisor. Without that, very early output
from the bootblock is garbled, specifically the coreboot welcome banner,
build timestamp, etc.

BUG=chrome-os-partner:27220
TEST=Built and booted on nyan. Used a logic analyzer to verify that the TPM
i2c bus ran at 400KHz instead of 660KHz, and that the divisor was the expected
value. Measured boot time with and without EFS and verified that there was no
change. Spot checked the output for errors and verified that none of the
bootblock output was garbled.
