We've just decided to remove the only known use of the VBSD_SW_WP flag
in vboot (https://chromium-review.googlesource.com/c/575389), since it
was unused and never reliable on all platforms anyway. Therefore, we can
now also remove the coreboot infrastructure that supported it. It
doesn't really hurt anyone, but removing it saves a small bit of effort
for future platforms.

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.

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.

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.

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.

For the skylake/kabylake generation of PCH there is an ACPI workaround
for emmc/sd power state that involves disabling and re-enabling dynamic
clock gating after enabling power to the controller, before setting the
power state to D0.
Under certain conditions we have observed that the controller is not
powered and ready by the time the kernel attempts to read the PME
control and status register and so the system will hang while attempting
to read PCI config register 0x84.
To ensure that the controller is ready add a 2ms delay after re-enabling
dynamic clock gating and before setting the power state to D0.
This issue has been observed on eMMC, but the same workaround exists for
the SD card interface so the same delay is added there.
BUG=b:35587084
BRANCH=eve
TEST=manual stress testing of D0<>D3 transition across many devices
shows no hard hang after 2 days.

As per latest BWG, ucode reloading should be done at the end
of Mp Init, i.e., after PRMRR and other features are enabled.
No reloading specifically after SMM Relocation is required.
As, in the Common CPU MP Init code, we are already doing a
uCode load at the end of MP Init Feature Programming, hence,
the uCode loading after SMM relocation can be removed.

SMI code is very similar across Intel platforms. Move this code to
common/block/smi to allow it to be shared between platforms instead
of duplicating the code for each platform. smihandler.h has already
been made common so all it will contain is name changes and a move
to the common block location. Due to moving smihandler code, APL
changes are bundled here to show this change.
