The many different places to put vboot support in can be confusing.
Instead of using libverstage (which isn't enough since those functions are
sometimes called outside that, too), mention all stages where it can resides
explicitly.

As per discussion with lawyers[tm], it's not a good idea to
shorten the license header too much - not for legal reasons
but because there are tools that look for them, and giving
them a standard pattern simplifies things.
However, we got confirmation that we don't have to update
every file ever added to coreboot whenever the FSF gets a
new lease, but can drop the address instead.
util/kconfig is excluded because that's imported code that
we may want to synchronize every now and then.

This patch removes quite a bit of code duplication between cpu_to_le32()
and clrsetbits_le32() style macros on the different architectures. This
also syncs those macros back up to the new write32(a, v) style IO
accessor macros that are now used on ARM and ARM64.

unfortunately something about the new macro notation makes the compiler
evaluate it more efficiently (not recalculating the address between the
read and the write), so this was of limited value.

The TPM driver by default allocates a 4K transfer buffer on the stack,
which leads to lots of fun on boards with 2K or 3K stack sizes. On
RK3288 this ends up writing over random memory sections which dependent
on the memlayout of the day might contain timestamp data (no big deal)
or page tables (-> bad time).
This patch fixes the problem by reducing the buffer size to slightly
above 1K, which still seems to work as far as I can tell. There was
already some really odd code that #undef'ed this value and redefined it
with the lower number in one .c file (unfortunately not the one with the
buffer declaration), with no explanation whatsoever... I'm removing that
and just assume the smaller value will be fine for everything.

This code ports antirollback module and tpm library from platform/vboot_reference.
names are modified to conform to coreboot's style.
The rollback_index module is split in a bottom half and top half. The top half
contains generic code which hides the underlying storage implementation.
The bottom half implements the storage abstraction.
With this change, the bottom half is moved to coreboot, while the top half stays
in vboot_reference.

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.

On ARM platforms the TPM is not attached through LPC but through I2C.
This patch adds an I2C TPM driver that supports the following chips:
* Infineon SLB9635
* Infineon SLB9645
In order to select the correct TPM implementation cleanly, CONFIG_TPM
is moved to src/Kconfig and does the correct choice.

i2c tpm: Remove mostly useless delay code/tables.
I assume from the code in the TPM driver that the TPM spec defines
different types of delays and timeouts which each have a particular
duration, and that the TPM can tell you how long each type is if you ask
it. There was a large table, some members of a data structure, and a
function or two which managed the timeouts and figured their value for
different operations. The timeout values for the various "ordinals"
were never set in the vendor specific data structure, however, and
always defaulted to 2 minutes. Similarly the timeouts a, b, c, and d
were never overridden from their defaults. This change gets rid of all
the timeout management code and makes the "ordinal" timeout 2 minutes
and the a, b, c, and d timeouts 2 seconds, the larger of the two default
values.
This is a port from depthcharge to coreboot, original change:
