Configure core PRMRR first on all the cores and then follow
the SGX init sequence. Second microcode load would run the
MCHECK. To pass MCHECK, PRMRR on all cores needs to be
configured first. Hence, PRMRR configuration would be called
from soc_core_init while MP init for each core and then from
soc_init_cpus, BSP would call sgx_configure for each core
(including for itself). This code flow satisfies the MCHECK
passing pre-conditions; and apparently this patch fixes the
behavior of calling configure_sgx() “again” for BSP. (So
removed the TODO comment also).

To correct the SGX init sequence; PRMRR on all cores first
needs to be set, then follow the SGX init sequence. This
patch would refactor the common SGX code (and add needed
checks in the init sequence) so that SOC specific code can
call SGX init in correct order.

Add mp_current_microcode() function to get the microcode patch pointer.
Use this function to avoid reading the microcode patch from the boot

Instead of enabling power button SMI unconditionally, add a boot state
handler to enable power button SMI just before jumping to
payload. This ensures that:
1. We do not respond to power button SMI until we know that coreboot
is done.
2. On resume, there is no need to enable power button SMI. This avoids
any power button presses during resume path from triggering a
shutdown.

Do not use the global platform_i2c_transfer() function that can only be
implemented by a single driver. Instead, make a `struct device` aware
transfer() function the only interface function for I2C controller dri-
vers to implement.
To not force the slave device drivers to be implemented either above
generic I2C or specialized SMBus operations, we support SMBus control-
lers in the slave device interface too.
We start with four simple slave functions: i2c_readb(), i2c_writeb(),
i2c_readb_at() and i2c_writeb_at(). They are all compatible to respec-
tive SMBus functions. But we keep aliases because it would be weird to
force e.g. an I2C EEPROM driver to call smbus_read_byte().

* `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

Chrome OS systems rely on the write status register to enable/disable
flash write protection and disabling this opcode breaks the ability
to enable or disable write protection with flashrom.
Add a configure option for this feature that will disable the opcode
for Write Status commands unless CONFIG_CHROMEOS is enabled.
Tested to ensure that a default build without CONFIG_CHROMEOS has this
option enabled while a build with CONFIG_CHROMEOS does not. Also
ensured that when this option is disabled (for Chrome OS) then flashrom
can be used with the --wp-enable and --wp-disable commands, depending
on the state of the external write protect pin.

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`.

It has been observed on a number of platforms (baytrail, kaby lake)
that if serial console is not enabled in coreboot, but is enabled in
kernel (v4.4), then on resume kernel hangs. In order to fix this, add
support for enabling UART debug port controller on resume.
In order to decide whether UART debug port controller should be
enabled in ramstage, following things are checked in given order:
1. If coreboot has serial console enabled, there is no need to
re-initialize the controller.
2. This special action is taken only for UART debug port controller.
3. If boot is not S3 resume, then initialization is skipped.
4. Callback into SoC to check if it wants to initialize the
controller.
If all the above conditions are met, then UART debug port controller
is initialized and taken out of reset.
BUG=b:64030366
TEST=Verified with the entire patchset series that:
1. If coreboot does not have serial console enabled, but Linux kernel
has console enabled, then on resume, coreboot initializes UART debug
port controller.
2. If coreboot and Linux do not have serial console enabled, then
coreboot does not initialize UART debug port controller.
3. If coreboot has serial console enabled, there is no change in
behavior.

As per discussion with CSME team, ME is NOT using PCI Config
Space register HFSTS2 Bit 10 to update ME power-gated status.
ME goes to CM0-PG state after ME device becomes idle after
Bit 2 of MMIO register offset 0x800 (D0i3 Control - HECI1_D0I3C)
is being set.
And to retrieve the PG status of ME, one should read from the
PWRMBASE+offset 0x590 (which should give the value 0xF9) and
PWRMBASE+offset 0x594 (which should give the value 0xFF).
But, also it needs some time for the ME FW to go to idle state
and reflect these values in PWRMBASE registers after D0i3 bit
is being set. This does not happen instantly.
So, in coreboot, if we read the ME PG state in finalize.c, which
happens just after FSP Notify phase, where actually ME D0i3 bit
is set, we do not read the correct PG state values (i.e, 0xF9
and 0xFF).
But, once it boots to Kernel, if we read those same registers
through iotool mmio_read32 command, we get correct values.
So, removing the ME PG state prints from coreboot, since it is
actually showing wrong information, although ME Power Gating is
successful.

Current implementation of itss_irq_init() uses 8 bit write access to
IRQ routing registers which is not supported on Apollo Lake.
This commit moves the register access from 8 bit to 32 bit so that this
function can be used with every platform.

coreboot was setting SPI FPR register to protect the
mrc_cache data range stored in flash. This programming was being done
after FSP Notify 1.
But, FSP was locking the SPI by setting FLOCKDN Bit during Notify
phase 1, due to which coreboot was unable to protect that range.
As solution, FSP introduced a new UPD SpiFlashCfgLockDown to skip
the lockdown of flash on interest of bootloader. Set that UPD to 0
to skip the lockdown of FAST_SPI flash from FSP.
The same is being done from coreboot after end of Post at finalize.c
file.
BUG=b:63049493
BRANCH=none
TEST=FPR can be set properly to protect the mrc_cache range. The
issue reported in the bug doesn't come when both software and
hardware WP is enabled with this patch.

Use 16bit write to avoid touching the upper two bytes that may cause
write cycle to fail in case a prior transaction has not completed.
This function sets the WRSDIS(Bit 11) and FLOCKDN (Bit 15) of the
SPIBAR + BIOS_HSFSTS_CTL. While WRSDIS is lockable with FLOCKDN,
writing both in the same cycle is guaranteed to work by design.
Avoid read->modify->write operation not to clear the RW1C bits
unintentionally.

Earlier 15ms time-out was kept for SPI transactions which was not
enough for SPI Erase transactions.
Increase the max time-out time to 5 secs which was present in SKL
before common code.
This increase in time-out won't disturb other SPI transactions like
Read, Write or Read Status, since, for those it will come out of
the loop once FDONE bit or FCERR bit is set.

A pad number is passed into gpi_status_get() to determine if its
associated bit is set from a generated event. However, the
implementation wasn't taking into account the gpi_status_offset
which dictates the starting offset for each community. Additionally,
the max_pads_per_group field is per community as well -- not global.
Fix the code to properly take into account the community's
gpi_status_offset as well as the max_pads_per_group.
