This patch implements the dram init setting by replacing the hard-coded
init sequence with a series of functions to support calibration for more

Initialize the input_hertz and uart_pci_addr fields of the lb_serial
struct to prevent later undefined reads in lb_add_serial(). This was
done for exynos5420 in commit ff94e00362 (soc/samsung/exynos5420/uart.c:
Init new serial struct variables), and this patch finishes the rest.
Note that not all of the drivers can have the UART PCI address
configured at build time, so a follow-up patch will be needed to correct
those ones.

This patch uprevs the Arm Trusted Firmware submodule to the new upstream
master (commit 42cdeb930).
Arm Trusted Firmware unified a bunch of stuff related to BL31 handoff
parameters across platforms which involved changing a few names around.
This patch syncs coreboot back up with that. They also made header
changes that now allow us to directly include all the headers we need
(in a safer and cleaner way than before), so we can get rid of some
structure definitions that were duplicated. Since the version of entry
point info parameters we have been using has been deprecated in Trusted
Firmware, this patch switches to the new version 2 parameter format.
NOTE: This may or may not stop Cavium from booting with the current
pinned Trusted Firmware blob. Cavium maintainers are still evaluating
whether to fix that later or drop the platform entirely.
Tested on GOOGLE_KEVIN (rk3399).

The default voltage of vsim2 is set to 2.76V for sim card usage.
In general, 2.76V of vsim2 is composed of 2.7V main voltage and 0.06V calibration voltage.
However, vsim2 is used for the tx_ovdd power of display port IT6505 on the kukui board design which needs 2.7V.
So we set it to 2.7V with modifying calibration value.

When <symbols.h> was first introduced, it only declared a handful of
regions and we didn't expect that too many architectures and platforms
would need to add their own later. However, our amount of platforms has
greatly expanded since, and with them the need for more special memory
regions. The amount of code duplication is starting to get unsightly,
and platforms keep defining their own <soc/symbols.h> files that need
this as well.
This patch adds another macro to cut down the definition boilerplate.
Unfortunately, macros cannot define other macros when they're called, so
referring to region sizes as _name_size doesn't work anymore. This patch
replaces the scheme with REGION_SIZE(name).
Not touching the regions in the x86-specific <arch/symbols.h> yet since
they don't follow the standard _region/_eregion naming scheme. They can
be converted later if desired.

A very common pattern in drivers is that we need to wait for a condition
to become true (e.g. for a lock bit in a PLL status register to become
set), but we still want to have a maximum timeout before we treat it as
an error. coreboot uses the stopwatch API for this, but it's still a
little verbose for the most simple cases. This patch introduces two new
helper macros that wrap this common application of the stopwatch API in
a single line: wait_ms(XXX, YYY) waits for up to XXX milliseconds to see
if the C condition 'if (YYY)' becomes true. The return value is 0 on
failure (i.e. timeout expires without the condition becoming true) and
the amount of elapsed time on success, so it can be used both in a
boolean context and to log the amount of time waited.
Replace the custom version used in an MTK ADC driver with this new
generic version.

The romstage main() entry point on arm64 boards is usually in mainboard
code, but there are a handful of lines that are always needed in there
and not really mainboard specific (or chipset specific). We keep arguing
every once in a while that this isn't ideal, so rather than arguing any
longer let's just fix it. This patch moves the main() function into arch
code with callbacks that the platform can hook into. (This approach can
probably be expanded onto other architectures, so when that happens this
file should move into src/lib.)
Tested on Cheza and Kevin. I think the approach is straight-forward
enough that we can take this without testing every board. (Note that in
a few cases, this delays some platform-specific calls until after
console_init() and exception_init()... since these functions don't
really take that long, especially if there is no serial console
configured, I don't expect this to cause any issues.)

is enabled, only 25088 (66%) bytes are needed.

There have been discussions about removing this since it does not seem
to be used much and only creates troubles for boards without defaults,
not to mention that it was configurable on many boards that do not
even feature uart.
It is still possible to configure the baudrate through the Kconfig
option.

Split `i2c.h` into three pieces to ease reuse of the generic defi-
nitions. No code is changed.
* `i2c.h` - keeps the generic definitions
* `i2c_simple.h` - holds the current, limited to one controller driver
per board, devicetree independent I2C interface
* `i2c_bus.h` - will become the devicetree compatible interface for
native I2C (e.g. non-SMBus) controllers

Our current struct for I2C segments `i2c_seg` was close to being compa-
tible to the Linux version `i2c_msg`, close to being compatible to SMBus
and close to being readable (e.g. what was `chip` supposed to mean?) but
turned out to be hard to fix.
Instead of extending it in a backwards compatible way (and not touching
current controller drivers), replace it with a Linux source compatible
`struct i2c_msg` and patch all the drivers and users with Coccinelle.
The new `struct i2c_msg` should ease porting drivers from Linux and help
to write SMBus compatible controller drivers.
Beside integer type changes, the field `read` is replaced with a generic
field `flags` and `chip` is renamed to `slave`.
Patched with Coccinelle using the clumsy spatch below and some manual
changes:
* Nested struct initializers and one field access skipped by Coccinelle.
* Removed assumption in the code that I2C_M_RD is 1.
* In `i2c.h`, changed all occurences of `chip` to `slave`.
