Previously the ME PCI interface (HECI) was being reported as present in
the DMAR ACPI table even when ME firmware was missing or the PCI device
was hidden and HECI would be unresponsive.
Now we check via the PCI config space itself to verify if the HECI
is present or not.
Note that this test could fail if ME firmware is present but
HECI is disabled in devicetree, because it would not advertise that the HECI
exists even though there is a running ME. Perhaps this behaviour is desirable
because in this case you won't see the HECI in the lspci tree anyway.

With a SPI clock above about 24MHz the APB cannot keep up when doing
individual byte transfers. Adjust the driver to use 16-bit reads when
it can, to remove this bottleneck.
Any transaction which involves writing bytes still uses 8-bit transfers,
to simplify the code. These are the transfers that are not time-critical
since they tend to be small. The case that really matters is reading from
SPI flash.
In general we can use 16-bit reads anytime we are transferring an even
number of bytes. If the code detects an odd number of bytes, it tries to
perform the operation in two steps: once in 16-bit mode with an even
number of bytes, and once in 8-bit mode for the final byte. This allow
us to use 16-bit reads even if asked to transfer (for example) 0xf423
bytes.
The limit on in_now and out_now is adjusted to 0xfffe to avoid an extra
transfer when transferring ~>=64KB.

Several of the special function pins we're using in firmware have a
pre-assigned pull-up or pull-down on power-on reset. We don't want those
to interfere with any of the signaling we're trying to do on those pins,
so this patch disables them.
Also do some house-cleaning to group the bootblock code better, and
change the setup code for all SPI and I2C buses to first initialize the
controller and then mux the pins... I assume this might be a little
safer (in case the controller peripheral has some pins in a weird state
before it gets fully initialized, we don't want to mux it through too
early).

layer that provides appropriate access to the chip. Move this into
a tpm_vendor_probe() function so it can use iic_tpm_read() with all

directly from the wrong layer.

For an unknown reason the printed address in the SPI debug messages is
modified before it is printed by subtracting the constant 0xf020 from
the passed in address.
What I suppose this debug code should do is to print the used register
address within the SPI controller while any parts of this address that
belongs to the SPI base address should be omitted. To fix that remove
the subtraction of 0xf020 and adjust the address mask to 0x3ff so that
only the offset to the registers inside the SPI controller will be
visible in the debug messages.
In addition switch to uint8_t and friends over u8 to sync up with used
types in this file.

According to "G45: Volume 3: Display Register
Intel 965G Express Chipset Family and Intel
G35 Express Chipset Graphics Controller" some registries
are set incorrectly in gm45/gma.c.
Some values are changed after comparing them with the values
the i915 linux kernel (3.13 was used) module sets while modesetting.
The values were obtained using 'intel_reg' from intel-gpu-tools,
during a normal boot and with 'nomodeset' as a kernel argument.
Some registers that don't exist on gm45 are set in gma.c, which is
probably the result of copying code from a more recent intel
northbridge.
The result is that that gm45 laptops with wxga displays still work as
before. gm45 laptops with wxga+ or higher resolution now just work,
where previously a black screen was shown.
TEST: build with native graphic init and flash on a gm45 target, like
lenovo x200.

If the TPM completely fails to respond then the vendor structure may not
have assigned handlers yet, so catch that case and return error so the
boot can continue to recovery mode instead of asserting over and over.

Add code to generate an ACPI descriptor for an I2C TPM based
on the device as described in devicetree.cb.
This currently requires the devicetree to provide the HID,
since we don't currently talk to the TPM in ramstage and I
didn't want to add yet another init path for it here.
This was tested on a reef board to ensure that the device
is described properly in the SSDT.

Add support for the cr50 TPM used in apollolake chromebooks.
This requires custom handling due to chip limitations, which
may be revisited but are needed to get things working today.
- timeouts need to be longer
- must use the older style write+wait+read read protocol
- all 4 bytes of status register must be read at once
- same limitation applies when reading burst count from status reg
- burst count max is 63 bytes, and burst count behaves
slightly differently than other I2C TPMs
- TPM expects the host to drain the full burst count (63 bytes)
from the FIFO on a read
Luckily the existing driver provides most abstraction needed to
make this work seamlessly. To maximize code re-use the support
for cr50 is added directly instead of as a separate driver and the
style is kept similar to the rest of the driver code.
This was tested with the cr50 TPM on a reef board with vboot
use of TPM for secdata storage and factory initialization.

Allow the sleep durations used by the driver to be set by the
specific chip so they can be tuned appropriately.
Since we need to read the chip id to know the values use very
conservative defaults for the first command and then set it
to the current values by default.

Use CAR accessors where needed for accessing static data.
In some cases this required some minor restructuring to pass
in a variable instead of use a global one.
For the tpm_vendor_init the structure no longer has useful
defaults, which nobody was depending on anyway. This now
requires the caller to provide a non-zero address.
Tested by enabling I2C TPM on reef and compiling successfully.

As far as I know, the Cortex-A53 cores in RK3399 are of a newer revision
that is not affected by ARM erratum 843419. If it was, the workaround
would also need to be enabled in libpayload and Chrome OS userspace,
which it currently isn't. I assume this was just incorrectly copied over
from another SoC and we can safely remove it.

Write speed is less important since there are very few writes and they

If we setup the PWM _after_ the pinmux then there's a period of time
when we're driving the PWM incorrectly. Let's setup the regulator and
_then_ configure the pinmux.
This fixes no known bugs, but it is more correct and probably makes the
signals look better at bootup.

Use the config switch CONFIG_DEBUG_SPI_FLASH on compiler level rather
then on preprocessor level to ensure that the code is compiled even if
the switch is not selected. In addition the following two changes are
introduced:
1. Prepend the debug messages with 'SPI:' to make the output more
meaningful.
2. Change the address mask from 0xffff to 0x3ff and remove the subtraction
of the constant value 0xf020 in order to print only the register
offset within the SPI controller and avoid the visibility of any
fragments from SPI base address.
3. Switch to uint8_t and friends instead of u8 to sync up with other
code in the same file.
