76e70675d9 ACPI: Add RHSA and ANDD structures for DMAR table
Remapping Hardware Status Affinity (RHSA) structure is applicable for
platforms supporting non-uniform memory. An ACPI Name-space Device
Declaration (ANDD) structure uniquely represents an ACPI name-space
enumerated device capable of issuing DMA requests in the platform.
Add RHSA and ANDD structures support for DMAR table generation.

0a9be33a8a soc/intel/common/timer: Calculate TSC frequency based on CPUID 0x15
This patch ensures to follow Intel SDM Vol 3B Sec 18.7.3 to
calculate nominal TSC frequency.

As per SDM recommendation:
For any processor in which CPUID.15H is enumerated and
MSR_PLATFORM_INFO[15:8] (which gives the scalable bus frequency) is
available, a more accurate frequency can be obtained by using CPUID.15H

This patch also adds header file to capture Intel  processor model number.

BUG=b:129839774
TEST=Boot ICL platform and calculate TSC frequency using below methods
1. TSC freq calculated based on MSR 0xCE
tsc: Detected 1600.000 MHz processor

2. TSC freq calculated based on CPUID 0x15
tsc: Detected 1612.800 MHz TSC

Method 2 actually reduce ~25ms of boot performance time.

Note: Method 2 is recommended from gen 6 processor onwards.

d2cdfff63b device/pci: Rewrite PCI MMCONF with symbol reference
The effect of pointer aliasing on writes is that any data on CPU
registers that has been resolved from (non-const and non-volatile)
memory objects has to be discarded and resolved. In other words, the
compiler assumes that a pointer that does not have an absolute value
at build-time, and is of type 'void *' or 'char *', may write over
any memory object.

Using a unique datatype for MMIO writes makes the pointer to _not_
qualify for pointer aliasing with any other objects in memory. This
avoid constantly resolving the PCI MMCONF address, which is a derived
value from a 'struct device *'.

0097f5589e vboot: standardize on working data size
Previously, the size of memory made for vboot_working_data
through the macro VBOOT2_WORK was always specified in each
individual memlayout file.  However, there is effectively no
reason to provide this customizability -- the workbuf size
required for verifying firmware has never been more than 12K.
(This could potentially increase in the future if key sizes
or algorithms are changed, but this could be applied globally
rather than for each individual platform.)

This CL binds the VBOOT2_WORK macro to directly use the
VB2_WORKBUF_RECOMMENDED_DATA_SIZE constant as defined by vboot
API.  Since the constant needs to be used in a linker script, we
may not include the full vboot API, and must instead directly
include the vb2_constants.h header.

2847e1e714 prog_loader: Associate TS_END_ROMSTAGE timestamp with postcar if exist
This patch adds timestamp for "end of romstage" with postcar if platform
has selected postcar as dedicated stage.

If postcar stage doesn't exist then "end of romstage" timestamp will get
call while starting of ramstage as exist today.

TEST=It's been observed that "end of romstage" timestamp doesn't appear
in "cbmem -t" log when ramstage is not getting executed. As part of this fix
"end of romstage" timestamp is showing in "cbmem -t" log on Intel platform
where POSTCAR is a dedicated stage.

db561e6e39 acpi: Sort the reported APIC-IDs in the MADT table
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.

7e0dea6317 symbols.h: Add macro to define memlayout region symbols
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.

8a41f4b71e device/pci_ops: Move questionable pci_locate() variants
These are defined for __SIMPLE_DEVICE__ when PCI
enumeration has not happened yet. These should not
really try to probe devices other than those on bus 0.

It's hard to track but there maybe cases of southbridge
being located on bus 2 and available for configuration, so
I rather leave the code unchanged. Just move these out of
arch/io.h because they cause build failures if one attempts
to include <arch/pci_ops.h> before <arch/io.h>.

There are two direct copies for ROMCC bootblocks to
avoid inlining them elsewhere.

This change will select the appropriate SMBIOS enclosure type based
on the selected system type.

This is important for the Intel Virtual Button driver as it does a
check on the SMBIOS enclosure type and only enables the tablet mode

4929f43619 arch/x86/acpigen: wrap _PLD in a package
The ACPI spec has an asl example for _PLD in the form:

Name (_PLD, Package (0x01) { ToPLD (PLD_Revision = 0x2) })

When I ported this to acpigen and diffed the results I noticed that
the binary blob was no longer provided within a package.  The ACPI
spec (section 6.1.8 in version 6.2) defines _PLD as "a variable-length
Package containing a list of Buffers".  This commit changes
acpigen_write_pld to use a package (the one existing caller I found
isn't wrapping the result in a package so it doesn't look like
it was intended for the callers of acpigen_write_pld to be responsible
for using a package.

BUG=none
BRANCH=none
TEST=Verified that after this change a package is use and the result
of acpigen matches what was used in the original asl.

08258881ed acpi: device: avoid empty property list in acpi_dp_write
If an acpi_dp table has children but no properties then acpi_dp_write()
will write out a properties UUID and package that contains no properties.
The existing function will avoid writing out a UUID and empty package
when no children exist, but it seems to assume that properties will
always be used.  With this change properties are handled in a manner
akin to children so that a UUID and package are only written if
properties exist.

BUG=none
BRANCH=none
TEST=Confirmed that prior to this change a UUID and empty package was
present for a device that had children but no properties.  Verified that
after this change the UUID and empty package are no longer present but
the child UUID and package are still present.

e1eca1d91c acpi_pld: Make it easier to define the ACPI USB device groups
The Linux kernel can use the ACPI _PLD group information to
determine peer ports.  Currently to define the group information
the devicetree must provide a complete _PLD structure.  This
change pulls the group information into a separate structure that
can be defined in devicetree.  This makes it easier to set for
USB devices in devicetree that do not need a full custom PLD.

This was tested on a sarien board with the USB devices defined
by verifying that the USB 2/3 ports are correctly identified
with their peer in sysfs.

caf6d0bc52 arch/x86: drop special case cbfs locator
CBFS used to have a special region for the x86 bootblock, which also
contained a pointer to a CBFS master header, which describes the
layout of the CBFS.

Since we adopted other architectures, we got rid of the bootblock region
as a separate entity and add the x86 bootblock as a CBFS file now.

The master header still exists for compatibility with old cbfstool
versions, but it's neatly wrapped in either the bootblock file or in a
file carefully crafted at the right location (on all other architectures).

All the layout information we need is now available from FMAP, a core
part of a contemporary coreboot image, even on x86, so we can just use
the generic master header locator in src/lib/cbfs.c and get rid of the
special version.

Among the advantages: the x86 header locator reduced the size of the
CBFS by 64 bytes assuming that there's the bootblock region of at least
that size - this breaks assumptions elsewhere (eg. when walking CBFS in
cbfs_boot_locate() because the last file, the bootblock, will exceed the
CBFS region as seen by coreboot (since it's CBFS - 64bytes).

TEST=emulation/qemu-q35 still boots

even get rid of HAVE_DISPLAY_MTRRS.

890788eb63 arch/x86: Fix car_active for CONFIG_NO_CAR_GLOBAL_MIGRATION
Change 76ab2b7 ("arch/x86: allow global .bss objects without
CAR_GLOBAL") allowed use of global .bss objects and hence moved around
the macros resulting in car_active returning 0 even for those boards
where CAR is actually active but do not require global migration. This
resulted in boards getting stuck when doing a reset in verstage because
the code flow incorrectly assumed that there was no CAR active and
hence triggered a cache invalidate.

This change fixes the above issue by returning 1 for car_active if
ENV_CACHE_AS_RAM is set even if global migration is not required.

BUG=b:109717603
TEST=Verified that board reset does not trigger cache invalidate in

83bd46e5e5 selfboot: remove bounce buffers
Bounce buffers used to be used in those cases where the payload
might overlap coreboot.

Bounce buffers are a problem for rampayloads as they need malloc.

They are also an artifact of our x86 past before we had relocatable
ramstage; only x86, out of the 5 architectures we support, needs them;
currently they only seem to matter on the following chipsets:
src/northbridge/amd/amdfam10/Kconfig
src/northbridge/amd/lx/Kconfig
src/northbridge/via/vx900/Kconfig
src/soc/intel/fsp_baytrail/Kconfig
src/soc/intel/fsp_broadwell_de/Kconfig

The first three are obsolete or at least could be changed
to avoid the need to have bounce buffers.
The last two should change to no longer need them.
In any event they can be fixed or pegged to a release which supports
them.

For these five chipsets we change CONFIG_RAMBASE from 0x100000 (the
value needed in 1999 for the 32-bit Linux kernel, the original ramstage)
to 0xe00000 (14 Mib) which will put the non-relocatable x86
ramstage out of the way of any reasonable payload until we can
get rid of it for good.

14 MiB was chosen after some discussion, but it does fit well:
o Fits in the 16 MiB cacheable range coreboot sets up by default
o Most small payloads are well under 14 MiB (even kernels!)
o Most large payloads get loaded at 16 MiB (especially kernels!)

With this change in place coreboot correctly still loads a bzImage payload.

Werner reports that the 0xe00000 setting works on his broadwell systems.

991467da4d arch/x86: Add BERT region support functions
Add code for generating the region pointed to in an ACPI Boot Error
Record Table.

The BERT region must be reported as Reserved to the OSPM, so this
code calls out to a system-specific region locator.  cbmem is
reported as type 16 and is not usable for the BERT region.

Events reported via BERT are Generic Error Data, and are constructed
as follows (see ACPI and UEFI specs for reference):
 * Each event begins with a Generic Error Status Block, which may
   contain zero or more Generic Data Entries
 * Each Generic Data Entry is identifiable by its Section Type field,
   and the data structures associated are also in the UEFI spec.
     * The GUIDs are listed in the Section Type field of the CPER
       Section Descriptor structure.  BERT doesn't use this structure
       but simply uses its GUIDs.
     * Data structures used in the Generic Data Entry are named as
       Error Sections in the UEFI spec.
         * Some sections may optionally include a variable number of
           additional structures, e.g. an IA32/X64 processor error
           can report error information as well as machine contexts.

It is worth noting that the Linux kernel (as of v4.4) does not attempt
to parse IA32/X64 sections, and opts to hexdump them instead.

7866d497ad arch/x86/acpi: Add DMAR RMRR helper functions
Add DMAR RMRR table entry and helper functions, using the existing
DRHD functions as a model. As the DRHD device scope (DS) functions
aren't DRHD-specific, genericize them to be used with RMRR tables as
well. Correct DRHD bar size to match table entry in creator function,
as noted in comments from patchset below.

4f51b0f7fe arch/x86: Fix payload loading via bounce-buffer
Fix regression (supposedly) after commit:

  23d62dd lib/bootmem: Add more bootmem tags

Without RELOCATABLE_RAMSTAGE, payload is allowed to overwrite
memory regions of the running ramstage. This case is handled
gracefully via a bounce-buffer implementation in arch/x86/boot.c.

4702914e34 acpi: device: Walk up the tree to find identifier
Instead of just checking the immediate parent for an device name,
walk up the tree to check if any parent can identify the device.

This allows devices to be nested more than one level deep and
still have them identified in one place by the SOC.

The recursive method calling this function has been changed to
handle a null return from acpi_device_name and abort instead of
continuing and perhaps forming an invalid ACPI path.

4b032e457f arch/x86: allow idt to be available to link in all stages
Add Kconfig IDT_IN_EVERY_STAGE to optionally specify having
the interrupt handling code available to all stages. In order
to do this the idt setup is moved to a C module. The vecX
entries are made global so that a table of references to all
the interrupt vector entry points can be used to dynamically
initialize the idt. The ramification for ramstage is that
exceptions are initialized later (lib/hardwaremain.c). Not
all stages initialize exceptions when this Kconfig variable
is selected, but bootblock for the C, stages using
assembly_entry.S, and of course ramstage do. Anything left
out just needs a call to exception_init() at the right
location.

0f35af8f42 arch/x86: add support for cache-as-ram paging
Processors, such as glk, need to have paging enabled while
in cache-as-ram mode because the front end is agressive about
fetching lines into the L1I cache. If the line is dirty and in
the L1D then it writes it back to "memory". However, in this case
there is no backing store so the cache-as-ram data that was written
back transforms to all 0xff's when read back in causing corruption.

In order to mitigate the failure add x86 architecture support for
enabling paging while in cache-as-ram mode. A Kconfig variable,
NUM_CAR_PAGE_TABLE_PAGES, determines the number of pages to carve
out for page tables within the cache-as-ram region. Additionally,
the page directory pointer table is also carved out of cache-as-ram.
Both areas are allocated from the persist-across-stages region
of cache-as-ram so all stages utilizing cache-as-ram don't corrupt
the page tables.

The two paging-related areas are loaded by calling
paging_enable_for_car() with the names of cbfs files to load the
initial paging structures from.

99f54a60bf include/memory_info.h: Change serial number field from 5 bytes to 4
dimm_info.serial had a strange contract. The SPD spec defines a 4 byte
serial number. dimm_info.serial required a 4 character ascii string with
a null terminator.

This change makes the serial field so it matches the SPD spec.
smbios.c will then translate the byte array into hex and set it on the
smbios table.

There were only two callers that set the serial number:
* haswell/raminit.c: already does a memcpy(serial, spd->serial, 4), so
  it already matches the new contract.
* amd_late_init.c: Previously copied the last 4 characters. Requires
  decoding the serial number into a byte array.

google/cyan/spd/spd.c: This could be updated to pass the serial number,
but it uses a hard coded spd.bin.

Testing this on grunt, dmidecode now shows the full serial number:
        Serial Number: 00000000

0a4e0fd913 cpu/intel/speedstep: Fix the PNOT ACPI method
The PNOT method never notifies the CPU to update it's _CST methods due
to reliance on inexisting variable (PDCx).

Add a method in the speedstep ssdt generator to notify all available
CPU nodes and hook this up in this file.

The cpu.asl file is moved to cpu/intel/speedstep/acpi since it now
relies on code generated in the speedstep ssdt generator. CPUs not
using the speedstep code never included this PNOT method so this is
a logical place for this code to be.

f1eb0ea537 arch/x86: Write ACPI DBG2 table only if the device has been enabled
The commit 93bbd41e (soc/intel: Enable ACPI DBG2 table generation)
causes a crash on the mainboard mc_apl1. On this mainboard all internal
SOC UARTs in the devicetree are switched off. As a result, no resources
are allocated to the UARTs. The function find_resource() expects an
existing resource. Otherwise, the CPU will stop. It should therefore not
only be queried whether a device is present, but also whether it is
enabled.

2d65d20436 arch/x86: Restore forwarding table on resume for non EARLY_EBDA_INIT
In commit c06a3f72 (arch/x86: initialize EBDA in S3 and S0/S5 path),
BDA and EBDA are wiped in the resume path. It results in coreboot
forwarding table address being wiped out since it is stored in the
BDA. This issue was resolved for platforms using EARLY_EBDA_INIT in
commit f46a9a0d (arch/x86: restore forwarding table on resume for
EARLY_EBDA_INIT). However platforms that do not use EARLY_EBDA_INIT
still run into the same issue and hence cbmem does not work on
resume. This change fixes the issue by using the stash/restore of
forwarding table address for all platforms using BDA.

There are two warnings:
* In LATE_CBMEM_INIT's help text, I've added a multi-line warning, that
  aims to explain the problem.
* In src/mainboard/Kconfig (just below the mainboard selection), there's
  a warning which points the user at LATE_CBMEM_INIT, if such a board is
  selected.

Also update the function that needs to be implemented, as pointed out by

returned NULL prior to the offending commmit.

ce9c88348c arch/x86/assembly_entry: Align stack for car_stage_entry
At process _start, the stack is expected to be aligned to a
16-byte boundary.  Upon entry to any function the stack frame
must have the end of any arguments also aligned.  In other words
the value of %esp+4 or %rsp+8 is always a multiple of 16 (1).

Align the stack down and change the method for executing
car_stage_entry from jmp to call which should preserve proper
alignment regardless of a 32- or 64-bit build.

Although 4-byte alignment is the minimum requirement for i386,
some AMD platforms use SSE instructions which expect 16-byte.

cd6b22f9a0 arch: Unify basic cache clearing API
Caching is a very architecture-specific thing, but most architectures
have a cache in general. Therefore it can be useful to have a generic
architecture-independent API to perform simple cache management tasks
from common code.

We have already standardized on the dcache_clean/invalidate naming
scheme that originally comes from ARM in libpayload, so let's just do
the same for coreboot. Unlike libpayload, there are other things than
just DMA coherency we may want to achieve with those functions, so
actually implement them for real even on architectures with
cache-snooping DMA like x86. (In the future, we may find applications
like this in libpayload as well and should probably rethink the API
there... maybe move the current functionality to a separate
dma_map/unmap API instead. But that's beyond scope of this patch.)

will use these functions with EARLY_CBMEM_INIT as well.

At the end of AmdInitPost() the decisions of UMA base and size
have not been written to hardware yet. The decisions are stored
inside AGESA heap object we cannot locate from coreboot proper
until after AmdInitEnv().

Modify code such that weak backup functions are only defined
for LATE_CBMEM_INIT; they are somewhat troublesome to handle.

e91d170d21 Remove libverstage as separate library and source file class
In builds without CONFIG_VBOOT_SEPARATE_VERSTAGE, verstage files are
linked directly into the bootblock or the romstage. However, they're
still compiled with a separate "libverstage" source file class, linked
into an intermediate library and then linked into the final destination
stage.

There is no obvious benefit to doing it this way and it's unclear why it
was chosen in the first place... there are, however, obvious
disadvantages: it can result in code that is used by both libverstage
and the host stage to occur twice in the output binary. It also means
that libverstage files have their separate compiler flags that are not
necessarily aligned with the host stage, which can lead to weird effects
like <rules.h> macros not being set the way you would expect. In fact,
VBOOT_STARTS_IN_ROMSTAGE configurations are currently broken on x86
because their libverstage code that gets compiled into the romstage sets
ENV_VERSTAGE, but CAR migration code expects all ENV_VERSTAGE code to
run pre-migration.

This patch resolves these problems by removing the separate library.
There is no more difference between the 'verstage' and 'libverstage'
classes, and the source files added to them are just treated the same
way a bootblock or romstage source files in configurations where the
verstage is linked into either of these respective stages (allowing for
the normal object code deduplication and causing those files to be
compiled with the same flags as the host stage's files).

Tested this whole series by booting a Kevin, an Elm (both with and
without SEPARATE_VERSTAGE) and a Falco in normal and recovery mode.

58c3938705 vboot: Move remaining features out of vendorcode/google/chromeos
This patch attempts to finish the separation between CONFIG_VBOOT and
CONFIG_CHROMEOS by moving the remaining options and code (including
image generation code for things like FWID and GBB flags, which are
intrinsic to vboot itself) from src/vendorcode/google/chromeos to
src/vboot. Also taking this opportunity to namespace all VBOOT Kconfig
options, and clean up menuconfig visibility for them (i.e. some options
were visible even though they were tied to the hardware while others
were invisible even though it might make sense to change them).

94d9411415 vboot: Remove CHIPSET_PROVIDES_VERSTAGE_MAIN_SYMBOL Kconfig option
CHIPSET_PROVIDES_VERSTAGE_MAIN_SYMBOL allows the SoC directory to
provide its own main() symbol that can execute code before the generic
verstage code runs. We have now established in other places (e.g. T210
ramstage) a sort of convention that SoCs which need to run code in any
stage before main() should just override stage_entry() instead. This
patch aligns the verstage with that model and gets rid of the extra
Kconfig option. This also removes the need for aliasing between main()
and verstage(). Like other stages the main verstage code is now just in
main() and can be called from stage_entry().

49342cd688 arch/x86: fix cmos post logging in non romcc bootblock
cmos_post_init() is called in src/arch/x86/bootblock_simple.c, and
that function is reponsible for bootstrapping the cmos post register
contents. Without this function being called none of the cmos post
functionality works correctly. Therefore, add a call to lib/bootblock.c
which the C_ENVIRONMENT_BOOTBLOCK SoCs use.

c9b398191e soc/intel/apollolake: allow ApolloLake SoC to use FSP CAR Init
FSP v2.0 Driver supports TempRamInit & TempRamExit APIs to initialize

ApolloLake SoC when CONFIG_FSP_CAR is enabled.

Verified on Intel Leaf Hill CRB and confirmed that Cache-As-Ram
is correctly set up and torn down using the FSP v2.0 APIs
without coreboot implementation of CAR init/teardown.

a01695bf9a Revert "arch/x86/smbios: Correct manufacturer ID"
This reverts commit c86da67436.

Alas, I have to disagree with this in every single line. The comment
added to the top of the file only applies to a single function therein
which sits over a hundred lines below. That's not much helpful. More-
over, the link in the comment is already down ofc.

The comment is also irritating as it doesn't state in which way (enco-
ding!) it applies to the code, which presumably led to the wrong in-
terpretation of the IDs.

At last, if anything should have changed it is the strings, the IDs
are resolved to. `smbios_fill_dimm_manufacturer_from_id()` has to
resolve the IDs it gets actually fed and not a random selection from
any spec.

Since I digged into it, here's why the numbers are correct: The func-
tion started with the SPD encoding of DDR3 in mind. There, the lower
byte is the number of a "bank" of IDs with an odd-parity in the upper
most bit. The upper byte is the ID within the bank. The "correction"
was to clear the parity bit for naught. The function was later exten-
ded with IDs in the DDR2-SPD encoding (which is actually 64-bit not
16). There, a byte, starting from the lowest, is either an ID below
127 plus odd-parity, or 127 which means look in the next byte/bank.
Unused bytes seem to be filled with 0xff, I guess from the 0xff2c.

Therefore, provide an option, PARALLEL_MP_AP_WORK, that allows
the APs to perform callbacks.

1e9a914207 arch/x86,lib: make cbmem console work in postcar stage
Implement postcar stage cbmem console support. The postcar stage
is more like ramstage in that RAM is already up. Therefore, in
order to make the cbmem console reinit flow work one needs the cbmem
init hook infrastructure in place and the cbmem recovery called.
This call is added to x86/postcar.c to achieve that. Additionally,
one needs to provide postcar stage cbmem init hook callbacks for
the cbmem console library to use. A few other places need to
become postcar stage aware so that the code paths are taken.
Lastly, since postcar is backed by ram indicate that to the
cbmem backing store.

e8c2e83973 arch/x86: Utilize additional MTRRs in postcar_frame_add_mtrr
In the current implementation of postcar_frame_add_mtrr,
if provided size is bigger than the base address alignment,
the alignment is considered as size and covered by the MTRRs
ignoring the specified size.
In this case the callee has to make sure that the provided
size should be smaller or equal to the base address alignment
boundary.

To simplify this, utilize additonal MTRRs to cover the entire
size specified. We reuse the code from cpu/x86/mtrr/mtrr.c.
