SD controller in CNL-PCH provides a ability to configure the behavior of
SD_VDD1_PWR_EN# as an active high or low signal. FSP provides an UPD
"SdCardPowerEnableActiveHigh" to control the same.
However, for platforms using SD_VDD1_PWR_EN# as active high, the SDXC
card connector is always powered and may impact system power. This is because
SD_VDD1_PWR_EN# does not de-assert during SDXC D3 or when SD card is not
inserted.
Workaround is to change the pad ownership of SD_VDD1_PWR_EN to GPIO and
force the TX buffer to low in _PS3. And restore the pad mode to native
function in _PS0.
Hence add a Kconfig option to update the UPD, which the board can select
based on how the SD_VDD1_PWR_EN is implemented on it. And, the workaround
gets applied based on this config.

Adapted from Chromium commit 5351dc0d
[Edgar: To set the RX ODT limit and dram geometry with RAMID detection]
Several cyan variants require memory init parameters be passed to FSP
for handling of specific Micron modules; without these, RAM init will
fail when loading training data from the MRC cache, and boot will halt.
This was missed when I upstreamed edgar along with the other cyan
variants, so add the required memory init parameters for edgar as per
its source Chromium branch.
Test: build/boot on edgar board with affected Micron memory
modules, verify boot successful with populated MRC cache.

PMC initialization on Cannon Lake happens earlier in the boot sequence
than other SoCs because FSP-Silicon init hides PMC from PCI bus. As
ACPI disabling was done as part of PMC init, it was being called
earlier than what other SoCs do. This resulted in a different order of
events for some drivers e.g. ChromeOS EC. In case of ChromeOS EC, it
ended up clearing EC events (which happens as part of ACPI disabling
in SMM) before logging any events of interest that happen during
mainboard initialization.
This change moves the call to disable ACPI to pmc_soc_init just like
other SoCs to keep the order of events more aligned.

coreboot performs MP-Init in a parallel way. That leads to the fact
that the order, in which the CPUs are woken up, can vary from boot to
boot. The creation of the MADT table just parses the devicetree and
takes the CPUs reported there as it is for creating the single local
APIC entries. Therefore, the OS will see different order of CPUs.
There are CPUs out there (like Apollo Lake for example) which have
shared caches on core-level and if the order is random this can end up
in assigning cores to different tasks or even OSes (in a virtual
environment) which uses the same cache. This in turn will produce
performance penalties across these distributed tasks/OSes.
Though there is a way to discover the core- and cache-topology it will
in the end be necessary to take the APIC-ID into account. To simplify
it, one can achieve the same output by sorting the APIC-IDs in an
ascending order. This will lead to the fact that CPUs that share a given
cache will be reported right next to each other in the MADT.

When <symbols.h> was first introduced, it only declared a handful of
regions and we didn't expect that too many architectures and platforms
would need to add their own later. However, our amount of platforms has
greatly expanded since, and with them the need for more special memory
regions. The amount of code duplication is starting to get unsightly,
and platforms keep defining their own <soc/symbols.h> files that need
this as well.
This patch adds another macro to cut down the definition boilerplate.
Unfortunately, macros cannot define other macros when they're called, so
referring to region sizes as _name_size doesn't work anymore. This patch
replaces the scheme with REGION_SIZE(name).
Not touching the regions in the x86-specific <arch/symbols.h> yet since
they don't follow the standard _region/_eregion naming scheme. They can
be converted later if desired.
