I2C bus SDA hold time can be marginal with 60ns value, especially
when there is level shifter on the bus. So program it to 300ns
based on Fast-mode specification, which is between 0 to 900ns.
Apply the same timing for Standard-mode as well.
Refer to original bug on BayTrail chrome-os-partner:28092, this
is to carry forward the fix to Broadwell.

Our CBFS header offset on rk3288 was very low and overlapped with the
end of the bootblock on recent Pinky builds. This can create all kinds
of fun effects like BSS variables suddenly being initialized to
something else than zero, in an effect that jumps somewhere else for
every slightest code size change.
This patch moves the CBFS header offset up a bit and the CBFS ROM offset
down (because there's really no point in leaving such a large gap). This
resolves our immediate booting problems, and I'll also start on a patch
to add further checks somewhere that catch these overlaps in the future.

This patch runs basic NAND initialization code on Proto 0.2 boards which
have been reworked for NAND. It makes sense to do this in coreboot for
two reasons:
- In general, it is reasonable for coreboot to initialize clocks and such
in preparation for depthcharge's use. Waiting times can be pooled, and
the initialization itself here is very fast.
- There is a kernel bug which requires that the clock is already initialized
before the kernel loads NAND support. coreboot is a more sensible place
to put a workaround than depthcharge because depthcharge initializes
things lazily, but when booting from USB, depthcharge won't need to look
at NAND.
This change involves bringing in an additional header file, ebi2.h, from U-Boot.
TEST=Booted a kernel from USB and verified that NAND came up without any
depthcharge hacks, whereas previously a USB-booted kernel would be unable
to access NAND even with the same drivers compiled in due to an initialization
failure.

We've had gpiolib.h which defines a few common GPIO access functions for
a while, but it wasn't really complete. This patch adds the missing
gpio_output() function, and also renames the unwieldy
gpio_get_in_value() and gpio_set_out_value() to the much easier to
handle gpio_get() and gpio_set(). The header is renamed to the simpler
gpio.h while we're at it (there was never really anything "lib" about
it, and it was presumably just chosen due to the IPQ806x include/
conflict problem that is now resolved).
It also moves the definition of gpio_t into SoC-specific code, so that
different implementations are free to encode their platform-specific
GPIO parameters in those 4 bytes in the most convenient way (such as the
rk3288 with a bitfield struct). Every SoC intending to use this common
API should supply a <soc/gpio.h> that typedefs gpio_t to a type at most
4 bytes in length. Files accessing the API only need to include <gpio.h>
which may pull in additional things (like a gpio_t creation macro) from
<soc/gpio.h> on its own.
For now the API is still only used on non-x86 SoCs. Whether it makes
sense to expand it to x86 as well should be separately evaluated at a
later point (by someone who understands those systems better). Also,
Exynos retains its old, incompatible GPIO API even though it would be a
prime candidate, because it's currently just not worth the effort.

In order to properly support more arm64 SoCs PSCI needs
to handle the hierarchy of cpus/clusters within the SoC.
The nodes within PSCI are kept in a tree as well as
a depth-first ordered array of same tree. Additionally,
the PSCI states are now maintained in a hierachal manner.
OFF propogates up the tree as long as all siblings are
set to OFF. ON propogates up the tree until a node is
not already set to OFF.
The SoC provides the operations for determining how many
children are at a given affinity level. Lastly, the
secmon startup has been reworked in that all non-BSP CPUs
wait for instructions from the BSP.

This patch is the start of a series to change all non-x86 SoC-specific
headers to be included as <soc/header.h> instead of the old
<soc/vendor/chip/header.h> or "header.h". It will add an include/soc/
directory under every src/soc/vendor/chip/ and append the .../include/
part of that to the global include path.
This matches the usage of <arch/header.h> for architecture-specific
headers and had already been done for some headers on Tegra. It has the
advantage that a source file which does not know the specific SoC used
(e.g. Tegra files common for multiple chips, or a global include file)
can still include SoC-specific headers and access macros/types defined
there. It also makes the includes for mainboard files more readable, and
reduces the chance to pull in a wrong header when copying mainboard
sources to use a different-related SoC (e.g. using a Tegra124 mainboard
as template for a Tegra132 one).
For easier maintainability, every SoC family is modified individually.
This patch starts out by changing Rk3288. Also alphabetized headers in
affected files since we touch them anyway.

Solving the DACR bug will mean that XN bits suddenly become enforced on
non-LPAE systems, and we will no longer be able to execute out of a
region mapped DCACHE_OFF. When we enable the MMU in romstage we are
still executing out of SRAM, so we would instantly kill ourselves.
Solve this issue by enabling the MMU earlier (in the bootblock) and
mapping the SRAM regions as DCACHE_WRITETHROUGH. They should really be
DCACHE_WRITEBACK, but it looks like there might be hardware limitations
in the Cortex-A12 cache architecture that prevent us from doing so.
Write-through mappings are equivalent to normal non-cacheable on the A12
anyway, and by using this attribute we don't need to introduce a new
DCACHE_OFF_BUT_WITHOUT_XN_BIT type in our API. (Also, using normal
non-cacheable might still have a slight speed advantage over strongly
ordered since it should fetch whole cache lines at once if the processor
finds enough accesses it can combine.)

This patch does some general cleanup in the Rockchip clock code, and
adds some more assertions regarding the PLL VCO and output frequency
ranges. It changes all PLL divisors to use the lowest values that can
still hit the target frequency, since higher NR values lead to higher
jitter and higher NO values increase power draw.
Also change DDR3 frequency code to hardcode the optimal divisors for
certail frequencies. As a little hack we will interpret 666000000 to
actually mean 666666666.6P (and analogous for 533MHz), since that's what
you usually want for memory.

Even though the code looks much different, the same basic algorithm
for setting up the transfer is used. The main difference is that
reads from rxdr and writes to txdr occur simultaneously and accounting
is more complicated, so I separated the higher-level accounting

Incidentally, it looks like CBFS_SIZE configuration setting is not
used on ARM platforms, this will have to be addressed separately.
