We have a tiny HEAP_SIZE by default, except when we don't, and
mainboards that override it, or not.
Since memory isn't exactly at a premium these days, and unused heap
doesn't cost anything extra, just crank it up to the highest value
we have in the tree by default and remove all overrides.

For recent X86 CPUs, the 0x15 CPUID instruction will return Time Stamp
Counter Frequence. For CPUs that do not support this instruction, EDK2
must include a different library which is the reason why this must be
configured at build time.
If this is enabled, and the CPU doesn't support 0x15, it will fail to
boot. If is not enabled, and the CPU does support 0x15, it will still
boot but without support for the leaf. Consequently, disabled it by
default.

2. Using MMIO access when GEN_PMCON_A is a memory mapped register.

This patch renames all FSP Notify Phase API configs to primarily remove
"SKIP_" prefix.
1. SKIP_FSP_NOTIFY_PHASE_AFTER_PCI_ENUM ->
USE_FSP_NOTIFY_PHASE_POST_PCI_ENUM
2. SKIP_FSP_NOTIFY_PHASE_READY_TO_BOOT ->
USE_FSP_NOTIFY_PHASE_READY_TO_BOOT
3. SKIP_FSP_NOTIFY_PHASE_END_OF_FIRMWARE ->
USE_FSP_NOTIFY_PHASE_END_OF_FIRMWARE
The idea here is to let SoC selects all required FSP configs to execute
FSP Notify Phase APIs unless SoC deselects those configs to run native
coreboot implementation as part of the `.final` ops.
For now all SoC that uses FSP APIs have selected all required configs
to let FSP to execute Notify Phase APIs.
Note: coreboot native implementation to skip FSP notify phase API (post
pci enumeration) is still WIP.
Additionally, fixed SoC configs inclusion order alphabetically.

One of the reason FSP-T support had to be kept in place was for
Intel Bootguard. This now works with native CAR code, so there is no
reason to keep FSP-T as an option for these platforms.
APL did not even build with FSP_CAR and finding FSP-T using walkcbfs
was only recently fixed using FMAP, so there can be no doubt that this
option was never used with coreboot master.

This change adds a common block driver for CNVi WiFi/BT controllers in
Intel SoCs. This driver uses the common PCI dev operations in addition
to generating ACPI device node and returning ACPI name for the
controller device.
This change also selects this driver for CML, GLK, ICL, JSL and TGL.

Kconfig 4.17 started using the $(..) syntax for environment variable
expansion while we want to keep expansion to the build system.
Older Kconfig versions (like ours) simply drop the escapes, not
changing the behavior.
While we could let Kconfig expand some of the variables, that only
splits the handling in two places, making debugging harder and
potentially messing with reproducible builds (e.g. when paths end up
in configs), so escape them all.

hard to maintain but also prone to errors.
To change that behaviour this commit introduces the

3rdparty/fsp.
If a SoC selects HAVE_INTEL_FSP_REPO the config option FSP_USE_REPO is
selected by default, but can be still deselected by the user in menuconfig.

The x86 timers are a bit of a mess. Cases where different stages use
different counters and timestamps use different counters from udelays.
The original intention was to only flip TSC_CONSTANT_RATE Kconfig
to NOT_CONSTANT_TSC_RATE. The name would be incorrect though, those
counters do run with a constant rate but we just lack tsc_freq_mhz()
implementation for three platforms.
Note that for boards with UNKNOWN_TSC_RATE=y, each stage will have a
slow run of calibrate_tsc_with_pit(). This is easy enough to fix with
followup implementation of tsc_freq_mhz() for the platforms.
Implementations with LAPIC_MONOTONIC_TIMER typically will not have
tsc_freq_mhz() implemented and default to UNKNOWN_TSC_RATE. However,
as they don't use TSC for udelay() the slow calibrate_tsc_with_pit()
is avoided.
Because x86/tsc_delay.tsc was using two different guards and nb/via/vx900
claimed UDELAY_TSC, but pulled UDELAY_IO implementation, we also switch
that romstage to use UDELAY_TSC.

Add explicit CBMEM_STAGE_CACHE option. Rename
CACHE_RELOCATED_RAMSTAGE_OUTSIDE_CBMEM to TSEG_STAGE_CACHE.
Platforms with SMM_TSEG=y always need to implement
stage_cache_external_region(). It is allowed to return with a
region of size 0 to effectively disable the cache.
There are no provisions in Kconfig to degrade from
TSEG_STAGE_CACHE to CBMEM_STAGE_CACHE.
As a security measure CBMEM_STAGE_CACHE default is changed to
disabled. AGESA platforms without TSEG will experience slower
S3 resume speed unless they explicitly select the option.

Re-add the Kconfig CONSOLE_UART_BASE_ADDRESS. It was lost by accident
on APL at least. It is used outside of soc/intel/ scope, e.g. to con-
figure SeaBIOS.
As we only ever configure a single UART for the coreboot console, we
don't need different addresses for each possible UART. Which saves
us a lot of code.

The option to specify a binary file name was added later for platforms
that do not provide microcode updates in our blobs repository. Alas,
it wasn't visible what platforms these are. And if you specified a file
for a platform that already had one, they were all included together.
Make it visible which platforms don't provide binaries with the new con-
figs MICROCODE_BLOB_NOT_IN_BLOB_REPO, MICROCODE_BLOB_NOT_HOOKED_UP and
MICROCODE_BLOB_UNDISCLOSED. Based on that we can decide if we want to
include binaries by default or explicitly show that no files are inclu-
ded (default to CPU_MICROCODE_CBFS_NONE).
Also split CPU_MICROCODE_CBFS_GENERATE into the more explicit
CPU_MICROCODE_CBFS_DEFAULT_BINS and CPU_MICROCODE_CBFS_EXTERNAL_BINS.
And clean up the visibility of options: Don't show CBFS related options
on platforms that don't support it and don't show external file options
if the platform uses special rules for multiple files (CPU_MICROCODE_
MULTIPLE_FILES).

Everything is wrong here, the Kconfig symbols are only the tip of the
iceberg. Based on Kconfig prompts the SoC code performed pad configu-
rations! I don't see why the person who configures coreboot should have
the board schematics at hand.
As a mitigation, we remove the prompts for UART_DEBUG, which is renamed
to INTEL_LPSS_UART_FOR_CONSOLE (because the former didn't really say
what it's about), and for UART_FOR_CONSOLE in case the former is selec-
ted.

Above macros are guarded using a newly added Kconfig option
SOC_INTEL_COMMON_BLOCK_GPIO_DUAL_ROUTE_SUPPORT that is selected only
by SoCs that have been validated to allow dual route of

Make use of the common CF9 reset in SOC_INTEL_COMMON_RESET. Also
implement board_reset() as a "full reset" (aka. cold reset) as that
is what was used here for hard_reset().
Drop soc_reset_prepare() thereby, as it was only used for APL. Also,
move the global-reset logic.
We leave some comments to remind us that a system_reset() should
be enough, where a full_reset() is called now (to retain current
behaviour) and looks suspicious.
Note, as no global_reset() is implemented for Denverton-NS, we halt
there now instead of issuing a non-global reset. This seems safer;
a non-global reset might result in a reset loop.

With https://github.com/IntelFsp/FSP/pull/4 merged, this allows using
Intel's FSP repo (that we mirror) to build a complete BIOS ifd region
with a simple coreboot build, automatically drawing in headers and
binaries.
This commit covers Apollolake, Coffeelake, Skylake, and Kabylake.
Skylake is using Kabylake's FSP since its own is FSP 1.1 and Kabylake's
also supports Skylake.
Another candidate (given 3rdparty/fsp's content) is Denverton NS, but
it requires changes to coreboot's FSP bindings to become compatible.
Cannonlake, Whiskeylake require an FSP release.

ifdtool has relied on one of the fields within FCBA(read_freq) to
determine whether a platform supports IFD_VERSION_1 or
IFD_VERSION_2. However, newer platforms like GLK and CNL do not have
read_freq field in FCBA and so the value of these bits cannot be used
as an indicator to distinguish IFD versions. In the long run, we need
to re-write ifdtool to have a better mapping of SoC to IFD fields. But
until that is done, this change adds a list of platforms that we know
do not support read_freq field but still use IFD_VERSION_2. This
change also updates GLK and CNL to pass in platform parameter to
ifdtool.

Add support and enalbe cache-as-ram paging for glk to work around
a cache-as-ram corruption issue. glk executes verstage, romstage,
and FSP-M directly out of cache-as-ram (just like apl). However,
the front end on glk is very agressive about pulling cache lines
into L1I for potential execution. When the snoops hit in the L1D
and the cache lines are dirty the processor writes the line back.
However, there is no backing store for the dirty lines to go. As
such when the line is pulled back in the value is all 0xff's,
corrupting cache-as-ram.
To fix the issue one needs to enable paging with NX (no execute)
permissions which prevents the above actions from happening because
the TLB will indicate that shouldn't be fetched into the instruction
cache since data will be marked no execute.
The generated page tables are added to cbfs and only added to the
COREBOOT cbfs as they are only consumed in the early cache-as-ram
stages.
The page tables generated with:
$ go run util/x86/x86_page_tables.go \
--iomap_file=src/soc/intel/apollolake/glk_page_map.txt \
--metadata_base_address=0xfef00000 \
