515ef38db4 arch/x86: SMBIOS: Improve core count reporting
Current code uses CPUID leaf 0x1, EBX bits 16:23 to determine number for
"core count". However, it turns out this number has little to do with
real number of cores. According to SDM vol 2A, it stays for "maximum
number of addressable IDs for logical processors in this physical
package". This does not seem to take into account fusing of giving
processor.

The new code determines 'core count' by dividing thread-level cpus by
reported logical cores. This seems to be the only way to arrive
to number of cores as it is reported in official CPU datasheet.

TEST=tested on OCP monolake

c05b1a66b3 Kconfig: Drop the C_ENVIRONMENT_BOOTBLOCK symbol
The romcc bootblock will be deprecated soon and most platforms use
C_ENVIRONMENT_BOOTBLOCK already. This patch drops the
CONFIG_C_ENVIRONMENT_BOOTBLOCK symbol and adds CONFIG_ROMCC_BOOTBLOCK
where needed.

7fc928656e lib/fmap: Disable pre-RAM cache for FSP 1.0
Due to the way CAR teardown is handled in FSP 1.0, the results of
car_get_var_ptr() aren't always reliable, which can break things when
running with FMAP cache. It might be possible to fix this but would make
the code rather complicated, so let's just disable the feature on these
platforms and hope they die out soon.

Also allow this option to be used by platforms that don't have space for
the cache and want to save a little more code.

This patch moves the traditional POSIX stdbool.h definitions out from
stdint.h into their own file. This helps for using these definitions in
commonlib code which may be compiled in different environments. For
coreboot everything should chain-include this stuff via types.h anyway
so nothing should change.

cefe89ee79 lib/fmap: Add optional pre-RAM cache
This patch adds an optional pre-RAM cache for the FMAP which most
platforms should be able to use, complementing the recently added
post-RAM FMAP cache in CBMEM. vboot systems currently read the FMAP
about half a dozen times from flash in verstage, which will all be
coalesced into a single read with this patch. It will also help
future vboot improvements since when FMAP reads become "free" vboot
doesn't need to keep track of so much information separately.

In order to make sure we have a single, well-defined point where the new
cache is first initialized, eliminate the build-time hardcoding of the
CBFS section offsets, so that all CBFS accesses explicitly read the
FMAP.

Add FMAP_CACHEs to all platforms that can afford it (other than the
RISC-V things where I have no idea how they work), trying to take the
space from things that look like they were oversized anyway (pre-RAM
consoles and CBFS caches).

1058dd84f0 security/vboot: Removed vboot_prepare from vboot_locator
When prog_locate() is called in the stage VBOOT is starting from and the
image to be loaded is not the target image vboot_prepare() may be called
too early.

To prevent this vboot_prepare() is removed from the vboot_locator
structure. This allows more control over the start of the vboot logic.

To clarify the change the vboot_prepare() has been renamed to
vboot_run_logic() and calls to initialize vboot have been added at the
following places:

postcar_loader: when VBOOT starts in ROMSTAGE
romstage_loader: when VBOOT starts in BOOTBLOCK
ramstage_loader: when VBOOT starts in ROMSTAGE

b1ef725f39 cpu/qemu-x86: Add x86_64 bootblock support
Add support for x86_64 bootblock on qemu.

Introduce a new approach to long mode support. The previous patch set
generated page tables at runtime and placed them in heap. The new
approach places the page tables in memory mapped ROM.

Introduce a new tool called pgtblgen that creates x86 long mode compatible
page tables and writes those to a file. The file is included into the CBFS
and placed at a predefined offset.

Add assembly code to load the page tables, based on a Kconfig symbol and
enter long in bootblock.

The code can be easily ported to real hardware bootblock.

Tested on qemu q35.

7c9a0e8a9c arch/x86: Use the stage argument to implement cbmem_top
Currently all stages that need cbmem need an implementation of a
cbmem_top function.  On FSP and AGESA platforms this proves to be
painful and a pointer to the top of lower memory if often passed via
lower memory (e.g. EBDA) or via a PCI scratchpad register.

The problem with writing to lower memory is that also need to be
written on S3 as one cannot assume it to be still there. Writing
things on S3 is always a fragile thing to do.

A very generic solution is to pass cbmem_top via the program argument.
It should be possible to implement this solution on every
architecture.

Instead trying to figure out which files can be removed from stages
and which cbmem_top implementations need with preprocessor, rename all
cbmem_top implementation to cbmem_top_romstage.

TESTED on qemu-x86.

0d6ddf8da7 cpu/x86/tsc: Flip and rename TSC_CONSTANT_RATE to UNKNOWN_TSC_RATE
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.

As code already used CBMEM hooks to switch from CAR to CBMEM
it was never necessary to have the structure declared inside
_car_relocatable_data.

Switch to use car_[get|set]_ptr is mostly for consistency, but
should also enable use of usbdebug with FSP1.0 romstage.

Keep track of the active timestamp table location using

can be located outside _car_relocatable_data and we only
switch the pointer to CBMEM and copy the data before
CAR gets torn down.

Fix comments about requirements of timestamp_init() usage.

Remove timestamp_cache from postcar and ramstage, as CBMEM
is available early on.
