Shaunak Saha bd427803ab soc/intel/common/block: Common ACPI
This patch adds the common acpi code.ACPI code is very similar
accross different intel chipsets.This patch is an effort to
move those code in common place so that it can be shared accross
different intel platforms instead of duplicating for each platform.
We are removing the common acpi files in src/soc/intel/common.
This removes the acpi.c file which was previously in
src/soc/common/acpi. The config for common acpi is
SOC_INTEL_COMMON_BLOCK_ACPI which can be defined in SOC's
Kconfig file in order to use the common ACPI code. This patch also
includes the changes in APL platform to use the common ACPI block.

TEST= Tested the patch as below:
1.Builds and system boots up with the patch.
2.Check all the ACPI tables are present in
  /sys/firmware/acpi/tables
3.Check SCI's are properly working as we are
  modifying the function to override madt.
4.Extract acpi tables like DSDT,APIC, FACP, FACS
  and decompile the by iasl and compare with good
  known tables.
5.Execute the extracted tables in aciexec to check
  acpi methods are working properly.

This is a bug introduced by this commit:
stoneyridge: Fix CPU ASL \_PR table [commit I870f81]

The following error is found in dmesg

 ACPI Error: [\_PR_.P000] Namespace lookup failure, AE_NOT_FOUND...

 acpi-cpufreq: overriding BIOS provided _PSD data

And, "ls -la /sys/devices/system/cpu/cpufreq/" doesn't work

The cause is that the Pstate SSDT table generated by AGESA expects CPU
variables \_PR.Pxxx, not \_PR.CPxx as generated by coreboot.
Use Kconfig to set the required string.

The Sideband Acces locking code is skipped from FSP by setting an
FSP-S UPD called PchSbAccessUnlock. This locking is being done in
coreboot during finalize.c.

This is done because coreboot was failing to disable HECI1 device
using Sideband interface during finalize.c if FSP already locks
the Sideband access mechanism before that.

So, as a solution, coreboot passes an UPD to skip the locking
in FSP, and in finalize.c, after disabling HECI, it removes the
Sideband access.

Pratik Prajapati 7a357eb865 soc/intel/skylake: Fix SGX init sequence
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).

Nico Huber 581738642f Reinvent I2C ops
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().

flash write protection and disabling this opcode breaks the ability

Add a configure option for this feature that will disable the opcode

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

Marc Jones 6bfcf666b0 stoneyridge: Fix CPU ASL \_PR table
The PMIO region was moved, but not updated in the ASL. Change to
generate \_PR table runtime and to report the correct PMIO region
and length.

Fix on Kahlee, where the EC overlaps the region:
[    0.802721] cros_ec_lpcs GOOG0004:00: couldn't reserve region0
[    0.807446] cros_ec_lpcs: probe of GOOG0004:00 failed with error -16

BUG=b:63902389
BRANCH=none
TEST=Cros_ec_lps can reserve the region. ACPI tables are correct.

Nico Huber 029dfff30c i2c: Move to Linux like `struct i2c_msg`
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`.
