1c8e8b259d arch/riscv: Avoid gcc11 replacing memset implementation with memset call
SBI comes with its own memset implementation (under a slightly
different name) that gcc11 "helpfully" tries to replace with a call
to memset(). Since we don't provide a memset, the linker isn't happy,
so prevent gcc from doing that.

6a73b2466f SMBIOS: Allow skipping default SMBIOS generation
The call to the `get_smbios_data` device operation is followed by
calls to unconditional default functions, which lacks flexibility.
Instead, have devices that implement `get_smbios_data` call these
default functions as needed.

Most `get_smbios_data` implementations are in mainboard code, and are
bound to the root device. The default functions only operate with PCI
devices because of the `dev->path.type != DEVICE_PATH_PCI` checks, so
calling these functions for non-PCI devices is unnecessary. QEMU also
implements `get_smbios_data` but binds it to the domain device, which
isn't PCI either.

Drop unused variables partitions, cache_line_size and number_of_sets as
struct cpu_cache_info.size  would provide the cache size directly.

0c6c0dac50 arch/x86: Helper functions to get deterministic cache parameters
This patch creates helper function that internally detects the CPU
type (AMD or Intel) and pick the leaf to send CPUID instruction with
different cache level to retrieve deterministic cache parameters.

Lists of helper functions generated as part of this CL :
1. cpu_check_deterministic_cache_cpuid_supported => if CPU has support
for deterministic cache using CPUID instruction.
2. cpu_get_cache_ways_assoc_info => Get cache ways for associativity.
3. cpu_get_cache_type => Get cache type.
4. cpu_get_cache_level => Get cache level.
5. cpu_get_cache_phy_partition_info => Get cache physical partitions.
6. cpu_get_cache_line_size => Get cache line size.
7. cpu_get_cache_sets => Get cache number of sets.
8. cpu_is_cache_full_assoc => Check if cache is fully associative.
9. cpu_get_max_cache_share => Cores are sharing this cache.
10. get_cache_size => Calculate the cache size.
11. fill_cpu_cache_info => Fill cpu_cache_info structure.

This change does the following:
* Pushes the cpu_info struct into the top of the stack (just like
  c_start.S). This is required so the cpu_info function works correctly.

* Adds the thread.c to the romstage build.

This patch changes byte order definition which is required for proper work

{le,be}*toh().

It also revealed bugs related to the endianness on BE targets that are

88eb167868 arch/x86: Save resume vector to stack in x86_64 mode
In x86_64, the first function parameter is passed in rdi register, and
the 32-bit code after exiting long mode reads the resume vector in
4(%esp), so it's needed to save the resume vector from rdi to 4(%rsp).

Also note that the function attribute "regparm" only works on x86-32
targets according to the GCC manual, so "asmlinkage" doesn't change
the ABI of an x86_64 function.

Tested on HP EliteBook 2560p. The laptop can resume from S3 in x86_64
mode after this change.

Introduce the `ARCH_ALL_STAGES_X86` Kconfig symbol to automatically
select the per-stage arch options. Subsequent commits will leverage
this to allow choosing between 32-bit and 64-bit coreboot where all
stages are x86. AMD Picasso and AMD Cezanne are the only exceptions
to this rule: they disable `ARCH_ALL_STAGES_X86` and explicitly set
the per-stage arch options accordingly.

8c9a89de99 arch/x86/ioapic: Drop irq_on_fsb as a configurable item
APIC Serial Bus pins were removed with ICH5 already, so a choice
'irq_on_fsb = 0' would not take effect. The related register BOOT_CONFIG
0x3 is also not documented since ICH5.

For emulation/qemu-q35 with ICH9 the choice INTERRUPT_ON_APIC_BUS was
wrong and ignored as BOOT_CONFIG register emulation was never implemented.

For ICH4 and earlier, the choice to use FSB can be made based on the
installed CPU model but this is now just hardwired to match P4 CPUs of
aopen/dxplplusu.

For sb/intel/i82371eb register BOOT_CONFIG 0x3 is also not defined
and the only possible operation mode there is APIC Serial Bus, which
requires no configuration.

d023909b01 treewide: Disable R_AMD64_32S relocation support
This fixes a hard to debug hang that could occur in any stage, but in
the end it follows simple rules and is easy to fix.

In long mode the 32bit displacement addressing used on 'mov' and 'lea'
instructions is sign-extended. Those instructions can be found using
readelf on the stage and searching for relocation type R_X86_64_32S.

The sign extension is no issue when either running in protected mode or
the code module and thus the address is below 2GiB. If the address is
greater than 2GiB, as usually the case for code in TSEG, the higher
address bits [64:32] are all set to 1 and the effective address is
pointing to memory not paged. Accessing this memory will cause a page
fault, which isn't handled either.

To prevent such problems
- disable R_AMD64_32S relocations in rmodtool
- add comment explaining why it's not allowed
- use the pseudo op movabs, which doesn't use 32bit displacement addressing
- Print a useful error message if such a reloc is present in the code

Fixes a crash in TSEG and when in long mode seen on Intel Sandybridge.

40acfe7f77 cbfs: Increase mcache size defaults
The CBFS mcache size default was eyeballed to what should be "hopefully
enough" for most users, but some recent Chrome OS devices have already
hit the limit. Since most current (and probably all future) x86 chipsets
likely have the CAR space to spare, let's just double the size default
for all supporting chipsets right now so that we hopefully won't run
into these issues again any time soon.

The CBFS_MCACHE_RW_PERCENTAGE default for CHROMEOS was set to 25 under
the assumption that Chrome OS images have historically always had a lot
more files in their RO CBFS than the RW (because l10n assets were only
in RO). Unfortunately, this has recently changed with the introduction
of updateable assets. While hopefully not that many boards will need
these, the whole idea is that you won't know whether you need them yet
at the time the RO image is frozen, and mcache layout parameters cannot
be changed in an RW update. So better to use the normal 50/50 split on
Chrome OS devices going forward so we are prepared for the eventuality
of needing RW assets again.

The RW percentage should really also be menuconfig-controllable, because
this is something the user may want to change on the fly depending on
their payload requirements. Move the option to the vboot Kconfigs
because it also kinda belongs there anyway and this makes it fit in
better in menuconfig. (I haven't made the mcache size
menuconfig-controllable because if anyone needs to increase this, they
can just override the default in the chipset Kconfig for everyone using
that chipset, under the assumption that all boards of that chipset have
the same amount of available CAR space and there's no reason not to use
up the available space. This seems more in line with how this would work
on non-x86 platforms that define this directly in their memlayout.ld.)

Also add explicit warnings to both options that they mustn't be changed
in an RW update to an older RO image.

20fa59fc2c arch/x86/smbios: Let SMBIOS type 9 be able to write slot ID
The slot ID can be passed in from the function caller but
parsing slot ID from devicetree is not yet supported and
would still be 0.

Add Slot ID in SMBIOS type 9 for Delta Lake.

Tested=Execute "dmidecode -t 9" to verify.

84d10cc5d3 ChromeOS: Use CHROMEOS_NVS guard
Replace CONFIG(CHROMEOS) with CONFIG(CHROMEOS_NVS) for cases where
the conditional and dependency are clearly about the presence of
an ACPI NVS table specified by vendorcode. For couple locations also
CONFIG(HAVE_ACPI_TABLES) changes to CONFIG(CHROMEOS_NVS).

This also helps find some of the CONFIG(CHROMEOS) cases that might
be more FMAP and VPD related and not about ChromeOS per-se, as
suggested by followup works.

1de8708fe5 cbfs: Remove prog_locate() for stages and rmodules
This patch removes the prog_locate() step for stages and rmodules.
Instead, the stage and rmodule loading functions will now perform the
locate step directly together with the actual loading. The long-term
goal of this is to eliminate prog_locate() (and the rdev member in
struct prog that it fills) completely in order to make CBFS verification
code safer and its security guarantees easier to follow. prog_locate()
is the main remaining use case where a raw rdev of CBFS file data
"leaks" out of cbfs.c into other code, and that other code needs to
manually make sure that the contents of the rdev get verified during
loading. By eliminating this step and moving all code that directly
deals with file data into cbfs.c, we can concentrate the code that needs
to worry about file data hashing (and needs access to cbfs_private.h
APIs) into one file, making it easier to keep track of and reason about.

This patch is the first step of this move, later patches will do the
same for SELFs and other program types.

82d16b150c memlayout: Store region sizes as separate symbols
This patch changes the memlayout macro infrastructure so that the size
of a region "xxx" (i.e. the distance between the symbols _xxx and _exxx)
is stored in a separate _xxx_size symbol. This has the advantage that
region sizes can be used inside static initializers, and also saves an
extra subtraction at runtime. Since linker symbols can only be treated
as addresses (not as raw integers) by C, retain the REGION_SIZE()
accessor macro to hide the necessary typecast.

7a5c369614 soc/intel/xeon_sp/cpx: Account for 'rc' heap manager
The xeon_sp/cpx has a second 'rc' heap inside FSP-M that is statically
allocated at the start of CAR. This breaks FSP 2.0 specification. This
can be worked around in the linker scripts to make sure coreboot and
FSP-M don't fight over the same memory.

Tested
- on ocp/deltalake: boot and the "Smashed stack detected in

7522a8fe0f arch/x86: Move prologue to .init section
For arch/x86 the realmode part has to be located within the same 64
KiB as the reset vector. Some older intel platforms also require 4 KiB
alignment for _start16bit.

To enforce the above, and to separate required parts of .text without
matching *(.text.*) rules in linker scripts, tag the pre-C environment
assembly code with section .init directive.

Description of .init section for ELF:

This section holds executable instructions that contribute to the
process initialization code. When a program starts to run, the
system arranges to execute the code in this section before calling the
main program entry point (called main for C programs).
