With RELOCATABLE_RAMSTAGE write-back cache of low ram is
only useful for bottom 1MiB of RAM as a small part of this gets used

This I2C controller has separate registers for different speeds to set
specific timing for SCL high and low times, and then a single register
to configure the SDA hold time.
For the most part these values can be generated based on the freq of
the controller clock, which is SOC-specific. The existing driver was
generating SCL HCNT/LCNT values, but not the SDA hold time so that is
added.
Additionally a board may need custom values as the exact timing can
depend on trace lengths and the number of devices on the I2C bus. This
is a two-part customizaton, the first is to set the values for desired
speed for use within firmware, and the second is to provide those
values in ACPI for the OS driver to consume.
And finally, recent upstream changes to the designware i2c driver in
the Linux kernel now support passing custom timing values for high
speed and fast-plus speed, so these are now supported as well.
Since these custom speed configs will come from devicetree a macro is
added to simplify the description:
register "i2c[4].speed_config" = "{
LPSS_I2C_SPEED_CONFIG(STANDARD, 432, 507, 30),
LPSS_I2C_SPEED_CONFIG(FAST, 72, 160, 30),
LPSS_I2C_SPEED_CONFIG(FAST_PLUS, 52, 120, 30),
LPSS_I2C_SPEED_CONFIG(HIGH, 38, 90, 30),
}"
Which will result in the following speed config in \_SB.PCI0.I2C4:
Name (SSCN, Package () { 432, 507, 30 })
Name (FMCN, Package () { 72, 160, 30 })
Name (FPCN, Package () { 52, 120, 30 })
Name (HSCN, Package () { 38, 90, 30 })

Support the common Intel LPSS I2C driver for the 6 I2C bus controllers
that are present on the Skylake-LP PCH with a 120 mHz clock. The
required lpss_i2c_base_address() method is implemented separately for
verstage/romstage and ramstage environments.
This provides methods to convert to and from "struct device" and the
I2C controller bus number for that device. These are used to provide
support for the "I2C Bus Operations" that are present in the coreboot
devicetree.
To support the I2C controller before ramstage an early init function
is provided to do minimal initializaiton of the PCI device and assign
a temporary base address for use before memory. The final base
address is assigned during device enumeration and used during ramstage.
Because it is usually not necessary to enable I2C controllers before
ramstage a config register for the devicetree is provided to perform
early initialization of this controller. In addition the bus speed
can be set in the devicetree and that speed will be applied when the
device is initialized. If not provided the default speed is set to
I2C_SPEED_FAST.
This was tested with the google/chell mainboard by reading and writing
from the trackpad and codec devices during both verstage and ramstage.

Add a generic LPSS I2C driver for Intel SOCs that use the Synopsys
DesignWare I2C block and have a similar configuration of that block.
This driver is ported from the Chromium depthcharge project where it
was ported from U-Boot originally, though it looks very different now.
From depthcharge it has been modified to fit into the coreboot I2C
driver model with platform_i2c_transfer() and use coreboot semantics
throughout including the stopwatch API for timeouts.
In order for this shared driver to work the SOC must:
1) Define CONFIG_SOC_INTEL_COMMON_LPSS_I2C_CLOCK_MHZ to set the clock
speed that the I2C controller core is running at.
2) Define the lpss_i2c_base_address() function to return the base
address for the specified bus. This could be either done by looking
up the PCI device or a static table if the controllers are not PCI
devices and just have a static base address.
The driver is usable in verstage/romstage/ramstage, though it does
require early initialization of the controller to set a temporary base
address if it is used outside of ramstage.
This has been tested on Broadwell and Skylake SOCs in both pre-RAM and
ramstage environments by reading and writing both single bytes across
multiple segments as well as large blocks of data at once and with
different configured bus speeds.
While it does need specific configuration for each SOC this driver
should be able to work on all Intel SOCs currently in src/soc/intel.

Add a PCI driver for the skylake SD card device and have it generate
an entry in the SSDT for the card detect GPIO if it is provided by the
mainboard in devicetree.
This sets up a card detect GPIO configuration that will trigger an
interrupt on both edges with a 100ms debounce timeout and can wake the
SD controller from D3 state.
The GpioInt() entry is bound to the "cd-gpio" device property which will
be consumed by the kernel driver.
The resulting ACPI output in the SSDT will be combined with the SDXC
device declaration in the DSDT.
Example:
Scope (\_SB.PCI0.SDXC)
{
Name (_CRS, ResourceTemplate () {
GpioInt (Edge, ActiveBoth, SharedAndWake, PullNone, 10000,
"\\_SB.PCI0.GPIO", 0, ResourceConsumer) { 35 }

with similar contents halfway through the "BIOS" region. This
second structure is referred as the logical boot partition 2 (LBP2),
and it's optionally employed.

cbfs_locate_file_in_region - to locate (and mmap) a file in a flash
region
This function is used to look for MMA blobs in "COREBOOT" cbfs region
(2) mma_setup_test.sh would write to "COREBOOT" region.
(3) changes in mma_automated_test.sh. Few MMA tests need system to
be COLD rebooted before test can start. mma_automated_test.sh would
do COLD reboot after each test, and so i would sync the filesystem

Allow the platform to override the input clock for the UART by
implementing the routine uart_platform_refclk and setting the Kconfig
value UART_OVERRIDE_REFCLK. Provide a default uart_platform_refclk
routine which is disabled when UART_OVERRIDE_REFCLK is selected. This
works around ROMCC not supporting weak routines.

On modern x86 platforms like apollolake, pre-RAM stages verstage and
romstage run within the cache-as-ram region. Thus, we do not need to
pass in the --xip parameter to cbfstool while adding these
stages. Introduce a new Kconfig variable NO_XIP_EARLY_STAGES which is
default false for all x86 platforms. Apollolake selects this option
since it supports code execution with CAR.

The flush L1D to L2 operation was only being used when loading
romstage from bootblock. However, when the FSP-M component is
loaded no code coherency actions are taken. I suspect this is
because the FSP-M component is larger than the 24KiB L1D and
the entry point is early in the image. Thus, when loading
the FSP-M component the earlier part of the image is flushed
out to L2 in the process of loading the latter part of the
component. Also, once verstage is introduced the same
code coherency actions need to be taken as well. Therefore,
position the apollolake code to handle all these cases.

A call to i2c_read() for a non-existent address followed by an i2c_read()
to a valid address results in a false abort status for the 2nd call.
i2c_read(1, 0x40, 0, buf, sizeof(buf)) => 0x2000000 (I2C_ERR_TIMEOUT)
i2c_read(1, 0x74, 0, buf, sizeof(buf)) => 0x4000000 (I2C_ERR_ABORT)
Because the abort status register is cleared on read and wait_tx_fifo()
reads it twice, the returned status does not contain the abort status.
Fixing that changed the 2nd read to reflect the abort status.
i2c_read(1, 0x40, 0, buf, sizeof(buf)) => 0x2000000 (I2C_ERR_TIMEOUT)
i2c_read(1, 0x74, 0, buf, sizeof(buf)) => 0x4000001 (I2C_ERR_ABORT)
Bit 0 indicates that the address was not acknowledged by any slave.
That's the abort status from the previous transaction.
So I added a read of the abort status before starting a transaction in
both i2c_read() and i2c_write().
i2c_read(1, 0x40, 0, buf, sizeof(buf)) => 0x2000000 (I2C_ERR_TIMEOUT)

The current Apollolake flow has its code executing out of
cache-as-ram for the pre-DRAM stages. This is different from
past platforms where they were just executing-in-place against
the memory-mapped SPI flash boot media. The implication is
that when cache-as-ram needs to be torn down one needs to be
executing out of DRAM since the act of cache-as-ram going
away means the code disappears out from under the processor.
Therefore load and use the postcar infrastructure to bootstrap
this process for tearing down cache-as-ram and subsequently
loading ramstage.
