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.

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.

There are many good reasons why we may want to run some sort of generic
callback before we're executing a reset. Unfortunateley, that is really
hard right now: code that wants to reset simply calls the hard_reset()
function (or one of its ill-differentiated cousins) which is directly
implemented by a myriad of different mainboards, northbridges, SoCs,
etc. More recent x86 SoCs have tried to solve the problem in their own
little corner of soc/intel/common, but it's really something that would
benefit all of coreboot.
This patch expands the concept onto all boards: hard_reset() and friends
get implemented in a generic location where they can run hooks before
calling the platform-specific implementation that is now called
do_hard_reset(). The existing Intel reset_prepare() gets generalized as
soc_reset_prepare() (and other hooks for arch, mainboard, etc. can now
easily be added later if necessary). We will also use this central point
to ensure all platforms flush their cache before reset, which is
generally useful for all cases where we're trying to persist information
in RAM across reboots (like the new persistent CBMEM console does).
Also remove cpu_reset() completely since it's not used anywhere and
doesn't seem very useful compared to the others.

FIT is already loading microcode before CPU Reset. So, we need
not update the microcode again in RO FW in bootblock.
But we need to update in RW FW if there is any new ucode version.
So, added the update microcode function in get_microcode_info callback
before MP Init to make sure BSP is using the microcode from cbfs.

cherry-pick from Chromium, commit 8fbe1e7
On Braswell and Baytrail devices, by userland 'perf top',
observed demanding clocks on __vdso_clock_gettime() since
chromeos_3.18 kernel; besides, evaluated massive calling of
clock_gettime() cost, up to 700 ns in average.
It turns out that Linux kernel of map_vdso() first call of
remap_pfn_range() does not fall into reserve_pfn_range()
due to size parameter, instead it relies on lookup_memtype()
and potentially be failed to be identified as eligible RAM
resource because the function of pat_pagerange_is_ram() actually
walks through root's sibling.
Meanwhile, on current BSW (and BYT) firmware implementation
makes System RAM resources located on child leaf, combining all
of these factors makes the kernel treat the vvar page of vdso
as a uncached-minus one leading slow access in result.
This patch recollects TOLM accessing; as Aaron recalled some
core_msr_script turns off access to TOLM register, he suggests
to store tolm to avoid getting back a zero while setting acpi
nvs space.
