Sometimes when bringing up a new board it can take a while until you
have all the peripheral drivers ready. For those cases it is nice to be
able to bitbang certain protocols so that you can already get further in
the boot flow while those drivers are still being worked on. We already
have this support for I2C, but it would be nice to have something for
SPI as well, since without SPI you're not going to boot very far.
This patch adds a couple of helper functions that platforms can use to
implement bit-banging SPI with minimal effort. It also adds a proof of
concept implementation using the RK3399.

A change introduced by commit fe4983e5 [1] in order to prevent
re-initialization of the TPM if already set up in verstage
had the wrong logic in the if statement, causing the TPM
to never be initialized if vboot is disabled.
The RESUME_PATH_SAME_AS_BOOT config is enabled by default for
ARCH_X86, resulting in the if statement to always evaluate to
false. Remove that condition from the if statement to allow it
to function as intended.
This patch also enables TPM initialization for FSP 2.0 with
the same conditions.

Most Intel platforms use separate registers for software-based

combined register (0xe0) for both. Adjust opregion implementation
to use the correct register for Atom-based platforms.

payload and non-VBIOS graphics init; observe Intel display
driver loaded correctly and internal display not blank.

The rationale is to allow the mainboard to override the default
baudrate for instance by sampling GPIOs at boot.
A new configuration option is available for mainboards to select
this behaviour. It will then have to define the function
get_uart_baudrate to return the computed baudrate.

The chip PCA9538 is a 8 bit I/O expander connected to the systems I2C
bus. Add a chip driver to support this chip.
Beside the pure chip driver two interface functions are provided to read
the state of the pins and write output values to the pins.
As the slave address of this chip is hardware configurable the function
pca9538_get_dev() is used to get the right slave address. This function
needs to be implemented in mainboard code if one needs to use the
interface functions to read and write I/O state.

The designware i2c controller indicates that the slave address
shouldn't be programmed while the controller is enabled. Therefore,
switch the ordering of the slave target address and the enable.
Additionally, ensure the controller is disabled prior to the
start of the slave programming sequence.
Lastly, chunk up the i2c_msg segments at differing slave address
boundaries. That allows for simpler programming for the controller
by only doing one slave address transaction chunk at a time.

This would cause failures to read on controllers when large requests

spi_flash_cmd_read_array_wrapped() function that calls
spi_flash_cmd_read_array() in a loop once the maximum transfer size is
calculated based on the spi controller's settings.

Right now dw_i2c_get_soc_cfg() is expecting the SoC to implement
that callback for obtaining the bus config. However, we're currently
forcing another parameter of struct device so one can do the lookup.
This works for Intel-based systems since the struct device was needed
to program the BAR, etc. However, from an API standpoint, it just
complicates matters by needing to obtain the struct device. The SoC
already has knowlege of its own devices so it can get the config
itself by bus number. Therefore, remove that contraint from the API.

This patch adds a member device_index to r8168 chip information which
allows driver to identify which NIC card requests MAC address.
In this implementation, only 10 NIC cards are supported, the device
index is in the range of 0 to 10. Regarding to MAC address mapping,
when there is only one NIC on DUT, it is treated as a special case
mapping to "ethernet_mac" in VPD for backward compatibility. When
there are multiple NICs on DUT, they are mapping to "ethernet_macN"
where N is [0-9].
Device tree configuration:
For single NIC: .device_index = "0", maps to "ethernet_mac"
For multiple NICs: .device_index = "[1-10]", maps to
"ethernet_mac[device_index - 1]"
BUG=b:69950854
BRANCH=None
TEST=Added device_index = [0-10] under /drivers/net in device tree &&
Programmed the mac address to VPD in shell
vpd -s ethernet_mac=<mac address> or
vpd -s ethernet-mac[0-9]=<mac address> && reboot the system.
Ensure the MAC address was fetched correctly by ifconfig command.

The Cr50 i2c driver provides separate entry points for probing and
initialization, but probing function does not really do much.
It also claims and releases locality on every coreboot stage, but
there is no need for this - locality should be definitely claimed
after reset and then it could be retained through the boot process.
On top of that the driver does not properly account for long time it
could take the Cr50 chip to come around to reset processing if TPM
reset request was posted during a lengthy TPM operation.
This patch addresses the issues as follows:
- tpm_vendor_probe() and tpm_vendor_cleanup() become noops, kept
around to conform to the expected driver API.
- tpm_vendor_init() invokes a function to process TPM reset only in
the first stage using TPM (typically verstage), the function
checks if locality is claimed and if so - waits for it to be
released, which indicates that TPM reset processing is over.
- before claiming locality check if it is already taken, and if so -
just proceed.

All coreboot stages using TPM start with the same sequence: check if
locality is claimed, if so, release it by writing 'active locality'
bit, then try claiming it.
This is actually not a proper procedure: section "5.5.2.3.1 Command
Aborts" of "TCG PC Client Platform TPM Profile (PTP) Specification
Level 00 Revision 00.430 Family 2" lists overwriting active locality
status bit as a means of triggering TPM command abort.
On top of that, none of the coreboot stages releases locality, it is
enough to claim it once when device starts booting.
In fact, locality being active when the device is in verstage is most
likely due to delayed TPM reset processing by the Cr50 TPM: reset is
an asynchronous event, and is processed once current command
processing completes.
The proper procedure is to wait if locality is active until it is
released (which will happen when Cr50 processes reset) and then
proceed to claim it. This needs to happen only during verstage, other
stages using TPM are guaranteed has been claimed earlier.

Once coreboot is ready and payload has been loaded a bit inside the NC
FPGA needs to be set to notify this event. As there are NC FPGAs with
different PCI device IDs save the BAR0 address in a global variable once
the driver evaluates this address. It can then be used to access the
register from the boot state machine callback without the need of searching
for all possible PCI devices again.
As this driver is only used at ramstage there is no need of using
CAR_GLOBAL for the global variable. Use a Kconfig switch to make this
feature selectable from mainboard as not every mainboard may have a FPGA
with that capability.

Although Intel's current spec[1] shows the OpRegion structure version
as being the top 16 bits of the field, Intel's Windows drivers
require the OpRegion structure version to be in the top 8 bits of
the field when not using a VGA BIOS (eg, NGI or GOP driver).
As the Linux i915 driver only checks that the version is >= 2,
there is no change in functionality there.
This change effectively matches Intel's implementation in TianoCore,
where the version is set to 0x0200 << 16.

This patch removes checks that ensure EC to be in RO for recovery
boot. We do not need these checks because when recovery is requested
automatically (as opposed to manually), we show 'broken' screen where
users can only reboot the device or request recovery manually.
If recovery is requested, Depthcharge will check whether EC is in RO
or not and recovery switch was pressed or not. If it's a legitimate
manual recovery, EC should be in RO. Thus, we can trust the recovery
button state it reports.
This patch removes all calls to google_chromeec_check_ec_image,
which is called to avoid duplicate memory training when recovery
is requested but EC is in RW.

It was originally designed such that if usbdebug_init() was called
before cbmem_initialize(), it would fetch the already-initialized
state from CBMEM. This changed when cbmem_find() behaviour changed
to require cbmem_initialize() to be called first. As a result,
ramstage had to reinitialize all of the EHCI controller and USB
endpoints on entry. This was slow, specially with AMD hardware
where one can scan USB ports to probe for the debug dongle.
For postcar and ramstage, move usbdebug entry such that it is
triggered from CBMEM_INIT_HOOK instead of console_init().
Side-effect of this is usbdebug console shows 'coreboot-xxx ...
starting...' line only for romstage.
Initialisation for usbdebug is never done in postcar. If you have
USBDEBUG_IN_ROMSTAGE=n, postcar will not have console output on
usb either.
While at it, fix also some other __PRE_RAM__ cases to ENV_ROMSTAGE
and alike.

With FSP 1.1, all FSP blobs are forward-compatible with newer FSP 1.1

This resolves a version mismatch issue with Braswell ChromeOS devices,

but older than the current Braswell FSP 1.1 header (1.1.7.0).

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`.
