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

f96d9051c2 Remove MIPS architecture
The MIPS architecture port has been added 5+ years ago in order to
support a Chrome OS project that ended up going nowhere. No other board
has used it since and nobody is still willing or has the expertise and
hardware to maintain it. We have decided that it has become too much of
a mainenance burden and the chance of anyone ever reviving it seems too
slim at this point. This patch eliminates all MIPS code and
MIPS-specific hacks.

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.

cbmem_top via calling arguments is not an option. To work around this
populate _cbmem_top_ptr with cbmem_top_chipset which is also used in
romstage.

d05f57cfcb arch/arm64: Pass cbmem_top to ramstage via calling argument
This solution is very generic and can in principle be implemented on
all arch/soc. Currently the old infrastructure to pass on information
from romstage to ramstage is left in place and will be removed in a
follow-up commit.

Nvidia Tegra will be handled in a separate patch because it has a
custom ramstage entry.

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.

Mechanisms set in place to pass on information from rom- to ram-stage
will be replaced in a followup commit.

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.

b3f24b4884 arm64: Uprev Arm TF and adjust to BL31 parameter changes
This patch uprevs the Arm Trusted Firmware submodule to the new upstream
master (commit 42cdeb930).

Arm Trusted Firmware unified a bunch of stuff related to BL31 handoff
parameters across platforms which involved changing a few names around.
This patch syncs coreboot back up with that. They also made header
changes that now allow us to directly include all the headers we need
(in a safer and cleaner way than before), so we can get rid of some
structure definitions that were duplicated. Since the version of entry
point info parameters we have been using has been deprecated in Trusted
Firmware, this patch switches to the new version 2 parameter format.

NOTE: This may or may not stop Cavium from booting with the current
pinned Trusted Firmware blob. Cavium maintainers are still evaluating
whether to fix that later or drop the platform entirely.

Tested on GOOGLE_KEVIN (rk3399).

These platforms return to romstage from FSP only after

region is available and discoverable via HOB.

Previously, CBMEM console detected on-the-fly that CAR
migration had happened and relocated cbmem_console_p
accoringlin with car_sync_var(). However, if the CAR_GLOBAL
pointing to another object inside CAR is a relative offset
instead, we have a more generic solution that can be used
with timestamps code as well.

On SKL/KBL/CML CPUID.15h.ecx = nominal core crystal clock = 0 Hz

Recommendation is to make use of CPUID.16h where crystal clock frequency
was not reported by CPUID.15h to calculate the crystal clock.

With RELOCATABLE_RAMSTAGE, S3 resume path only uses
memory that is reserved from OS. So there is no need
for low memory backup and recovery.

9172b6920c src: Remove variable length arrays
Variable length arrays were a feature added in C99 that allows the
length of an array to be determined at runtime. Eg.

	int sum(size_t n) {
		int arr[n];
		...
	}

This adds a small amount of runtime overhead, but is also very
dangerous, since it allows use of an unlimited amount of stack memory,
potentially leading to stack overflow. This is only worsened in
coreboot, which often has very little stack space to begin with. Citing
concerns like this, all instances of VLA's were recently removed from the
Linux kernel. In the immortal words of Linus Torvalds [0],

    AND USING VLA'S IS ACTIVELY STUPID! It generates much more code, and
    much _slower_ code (and more fragile code), than just using a fixed
    key size would have done. [...] Anyway, some of these are definitely
    easy to just fix, and using VLA's is actively bad not just for
    security worries, but simply because VLA's are a really horribly bad
    idea in general in the kernel.

This patch follows suit and zaps all VLA's in coreboot. Some of the
existing VLA's are accidental ones, and all but one can be replaced with
small fixed-size buffers. The single tricky exception is in the SPI
controller interface, which will require a rewrite of old drivers
to remove [1].

will need to be set dynamically based on sku.

0c4ed4bd7e arch, include, soc: Use common stdint.h
There are only minimal differences between the architecture specific
stdint.h implementations, so let's tidy them up and merge them together
into a single file. In particular,

- Use 'unsigned long' for uintptr_t. This was already the case for x86
  and riscv, while arm and mips used 'unsigned int', and arm64 and ppc64
  used 'unsigned long long'. This change allows using a single integer
  type for uintptr_t across all architectures, and brings it into
  consistency with the rest of the code base, which generally uses
  'unsigned long' for memory addresses anyway. This change required
  fixing several assumptions about integer types in the arm code.
- Use _Bool as the boolean type. This is a specialized boolean type that
  was introduced in C99, and is preferrable over hacking booleans
  using integers. romcc sadly does not support _Bool, so for that we
  stick with the old uint8_t.
- Drop the least and fast integer types. They aren't used
  anywhere in the code base and are an unnecessary maintenance burden.
  Using the standard fixed width types is essentially always better anyway.
- Drop the UINT64_C() macro. It also isn't used anywhere and doesn't
  provide anything that a (uint64_t) cast doesn't.
- Implement the rest of the MIN and MAX numerical limits.
- Use static assertions to check that the integer widths are correct.

fb49379ed2 device/pci_rom: Fix redundant pci_rom_probe() calls
For the PCI_VENDOR_ID_ATI case, we can rely on
pci_rom_acpi_fill_vfct() to make the call if necessary.

For hardware other than ATI, pci_rom_probe() was already
called from pci_rom_ssdt() and pci_dev_init(), so
PCI_ROM_ADDRESS BAR is already enabled, if requested so.

b379f1964e fit: Refactor config node handling
This patch makes some minor refactoring to the way the FIT parser
handles config nodes. A lot of this code was written in the dawn age of
depthcharge when its device tree library wasn't as well-stocked yet, so
some of it can be rewritten nicer with more high-level primitives.
There's no point in storing both the string name and the actual FDT node
of a FIT image node separately, since the latter also contains the
former, so remove that. Also eliminate code for the case of not having
an FDT (which makes no sense), and move some more FDT validity/compat
checking into fit_update_compat() (mostly in anticipation of later
changes).

This patch was adapted from depthcharge's http://crosreview.com/1553456
with a couple of modifications specific to coreboot's custom FIT loading
code.

01c83a2e99 3rdparty/blobs: Update submodule, SNB improvements
The sandybridge systemagent-r6 blob is modified:
- To be more flexible about the location of the stack w.r.t. the heap
- Place the MRC pool right below the MRC_VAR region
- to work with the same DCACHE_RAM_BASE from the native raminit (could
  make the CAR linker symbols easily compatible if desired)

This allows CAR setup compatibility between mrc.bin and native
bootpath and also allows for BIOS/memory mappeds region larger than
8MB.

This changes the semantics of CONFIG_DACHE_RAM_MRC_VAR_SIZE to also
include the pool on top of MRC_VAR region.

TESTED on T520 (boots and resumes from S3 with mrc.bin).
