The EC doesn't seem to be able to handle its bus running at 4 MHz or higher.
To avoid it not being able to keep up, we reduce the frequency of that bus on
all nyan derivatives to 3 MHz. Because PLLP can't be divided that low, we
switch the clock source to CLKM.

To ensure that the command1 write which sets the "go" bit completes before
other reads to the device. Otherwise, there's a race condition where those
register values might still have their values from the last transfer. With
different SPI clock frequencies, that could lead to spi_delay being told there
were negative bytes still to send. Its expected delay would wrap to a negative
value, that was passed to udelay, and the system would sit there for 4 seconds
not doing anything.

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

bootblock output was garbled.

The SPI drivers for tegra and exynos5420 have code in them which waits for a
frame header and leaves filler data out. The SPI driver shouldn't have support
for frame headers directly. If a device uses them, it should support them
itself. That makes the SPI drivers simpler and easier to write.
When moving the frame handling logic into the EC support code, EC communication
continued to work on tegra but no longer worked on exynos5420. That suggested
the SPI driver on the 5420 wasn't working correctly, so I replaced that with
the implementation in depthcharge. Unfortunately that implementation doesn't
support waiting for a frame header for the EC, so these changes are combined
into one.

To find the coreboot tables, the payload has historically searched for their
signature in a predefined region of memory. This is a little clumsy on x86,
but it works because you can assume certain regions are RAM. Also, there are
areas which are set aside for the firmware by convention. On x86 there's a
forwarding entry which goes in one of those fairly small conventional areas
and which points to the CBMEM area at the end of memory.
On ARM there aren't areas like that, so we've left out the forwarding entry and
gone directly to CBMEM. RAM may not start at the beginning of the address space
or go to its end, and that means there isn't really anywhere fixed you can put
the coreboot tables. That's meant that libpayload has to be configured on a
per board basis to know where to look for CBMEM.
Now that we have boards that don't have fixed amounts of memory, the location
of the end of RAM isn't fixed even on a per board level which means even that
workaround will no longer cut it.
This change makes coreboot pass the location of the coreboot tables to
libpayload using r0, the first argument register. That means we'll be able to
find them no matter where CBMEM is, and we can get rid of the per board search
ranges.
We can extend this mechanism to x86 as well, but there may be more
complications and it's less necessary there. It would be a good thing to do
eventually though.
BUG=None
TEST=Built and booted on nyan. Changed the size of memory and saw that the
payload could still find the coreboot tables where before it couldn't. Built
for pit, snow, and big.

The preceding patch copied gizmo2 from the amd/olivehill
board. This commit includes the changes required to make
the code reflect the gizmo2 hardware:
- Update the vendor Kconfig to add gizmo2
- Update the mainboard Kconfig
- Update devicetree
- Add support in for the soldered down DDR3
- Update the CODEC verb data
- Update the graphics connector settings
- Adjust the temperature thresholds for the fan
What's missing:
- Interrupt routing tables
Gizmo2 can boot DOS and Ubuntu 14.10.

Clang warns of an implicit conversion from 'double' to 'int'
e.g. changes value from '26.67' to '26'. Thus take the floor() of
the array and not change orginal behaviour.

- In '-ffreestanding' main() is just as any other function and so
it needs a type-signature. Fixes a clang warning.
- Bay Trail and Rangeley have the updated romstage.c with the code
moved into the chipset, put the prototype in romstage.c.
- The sandybridge code has not been updated, so the prototype
for it goes into chipset_fsp_util.h, next to the prototype for
romstage_main_continue.
- Correct the return value of baytrail main() from void * to void
and remove the unnecessary asmlinkage tag. I'm surprised that this
didn't generate a warning...
