48f96739ed soc/intel/skylake: Remove Heci2 and Heci3 from wake resource list
HECI2 and HECI3 devices are “function disable” during FSP
Silicon Init phase. Device will not be visible over PCI bus
hence removing these devices from wake source list.

b5a5aa6450 soc/intel/common/gpio: clean up logical to chipset mapping
1. Explicitly add LOGICAL to the reset macro name to make it explicit
   that the values are logical.
2. Reword some of the comments and combine them into single comment
   instead of scattering the comments throughout.
3. Use c99 struct initializers for the reset mapping array.
4. For the chipset specific values use literals that match the hardware.
5. Use 'U' suffixes on the literals so we don't trip up compiler being
   over zealous on undefined behavior.
6. Use unsigned and fixed-width types for the reset mapping structure
   since the code is reliant on matching up with a register definition.
7. Fix formatting that can fit < 80 cols.

aa2504a10e soc/intel/common/gpio: distingiush single vs multi acpi devices
Sadly, small core and big core are not aligned with the OS driver's
expectation on the number of ACPI devices used for each community.
Big core uses a single device while small cores use one ACPI device
per community. Allow for this distinction within the common gpio
implementation and ensure apollolake is utilizing the new option
to retain the correct behavior.

stack for the lzma decompression buffer. Therefore, reduce the stack

3214bc4ecc soc/intel/skylake: Remove “disable SaGv” in recovery mode flow
This reverts commit 5535cead (intel/skylake: Disable SaGv in 
recovery mode).

Commit 5535cead disables SaGv in recovery mode to save few seconds
booting time as we were doing memory training on every recovery flow.

Now we don't need to perform MRC training on every recovery boot
due to RECOVERY_MRC_CACHE implementation in place. Hence we don't
need to define different SaGv policy between Normal (developer) mode
and recovery mode to save few seconds.

Using different SaGv parameters between recovery and all other mode
has some significent drawbacks over warm reboot cycle. We are seeing
a MRC traning hang in eve/soraka/poppy devices with below use case.

Step 1: Boot system in developer mode (first time RW_MRC training)
Step 2: Set recovery_request=1 (using crossystem) and issue “reboot”
from OS
Step 3: System will perform recovery mode MRC training and boot to
OS (first time RECOVERY_MRC training)
Step 4: Issue “reboot” from OS console.
Step 5: System wil boot in developer mode (using RW_MRC cache)
Step 6: Set recovery_request=1 (using crossystem) and issue “reboot”
from OS
Step 7: System will pick RECOVERY_MRC_CACHE and will hang during
MRC training.

This patch fixes issue mentioned above and ensures system boot to
OS without any hang if we change mode (dev<->recovery) over warm
reset.

BUG=b:63515071
BRANCH=none
TEST=manual stress testing of dev<->recovery mode over warm boot.
No MRC hang with this fix on eve/soraka/poppy devices.

68243a5157 soc/amd/common: Add initial support for AMD PSP
Add files for supporting the BIOS->PSP communication not
covered by AGESA. The first command implemented notifies the
PSP that DRAM is ready.

This patch also introduces the amd/common/block directory
structure similar to intel/common/block.

a1de1a0810 soc/intel/skylake: Remove unnecessary P-State and Flex Ratio assignment
This patch basically does two things -

1) Remove unnecessary setting of flex_ratio to TDP nominal:
Factory configured (default) Max Non-TURBO ratio(P1) is already cofigured
in MSR_PLATFORM_INFO(0xCE).
If this Maximum Non-TURBO Ratio(P1) needs to be modified, it should be done
using MSR_FLEX_RATIO (0x194).
Here, in this code, the FLEX_RATIO is being modified by the TDP Nominal
Ratio, reading the MSR_CONFIG_TDP_NOMINAL(0x648). But this value is
actually less than the factory configured Maximum Non TURBO Ratio (P1).
So, this code is actually not required.

Also, the Bit 12 in PCH Soft Strap Register is already set in descriptor.
This Bit implies Processor Boot Max Frequency -
0 = Disable Boot Max Frequency
1 = Enable Boot Max Frequency (Default)
This setting determines if the processor will operate at maximum frequency
at power-on and boot.

Thus this patch will avoid one extra platform warm reset now onwards.

2) Remove wrongly setting Max Frequency in Bootblock phase:
In the function set_max_frequency(), the P-State max ratio was set to
TDP Nominal ratio if C-TDP was enabled, else it was set to Max Non
Trbo ratio.

But, when the cpu gets reset, it will operate with the Max-Non Turbo
ratio only, which is greater than the TDP Nominal ratio.
So, no need to set back the ratio to TDP Nominal which is lower than
the currently operating frequency.

BUG=none
BRANCH=none
TEST=Build and boot poppy
