Joel Kitching d6f71d03f1 vboot: fix STARTS_IN_BOOTBLOCK/_ROMSTAGE logic
Fix up the logic of when to include VBOOT2_WORK symbols on x86,
which are only needed when VBOOT_STARTS_IN_BOOTBLOCK is enabled.

Also correct the value of the __PRE_RAM__ macro in the case that
VBOOT_STARTS_IN_ROMSTAGE is selected.  In this case, DRAM is
already up and verstage should not be considered pre-ram.

Julius Werner 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.

Kyösti Mälkki 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.

Matt Delco 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.

If an acpi_dp table has children but no properties then acpi_dp_write()

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.

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.

Kyösti Mälkki 34856579f8 arch/x86: Drop Kconfig AP_SIPI_VECTOR
This was used to check romcc-built bootblock and romstage
agree about the location of 16-bit entrypoint. There was
no need to customize it as bootblock size requirement did
not grow. Just check for a fixed location at 4 GiB - 4 KiB.

With C_ENVIRONMENT_BOOTBLOCK we can have a proper symbol
for the purpose, since it appears in the same compilation
unit. It will adjust if C_ENV_BOOTBLOCK_SIZE changes.

Duncan Laurie 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.

Patrick Georgi 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

No need to hide it in soc/intel/.

To not bloat src/Kconfig up any further, start a new `Kconfig.debug`

If somebody wants to review the code if it's 100% generic, we could
even get rid of HAVE_DISPLAY_MTRRS.

resulted in boards getting stuck when doing a reset in verstage because
the code flow incorrectly assumed that there was no CAR active and

Ronald G. Minnich c308554c10 selfboot: create selfboot_check function, remove check param
The selfboot function was changed at some point to take a parameter
which meant "check the allocated descriptors to see if they target
regions of real memory."

The region check had to be buried deep in the last step of loading since
that is where those descriptors were created and used.

An issue with the use of the parameter was that it was not possible
for compilers to easily divine whether the check code was used,
and it was hence possible for the code, and its dependencies, to be
compiled in even if never used (which caused problems for the
rampayload code).

Now that bounce buffers are gone, we can hoist the check code
to the outermost level. Further, by creating a selfload_check
and selfload function, we can make it easy for compilers
to discard unused code: if selfload_check is never called, all
the code it uses can be discarded too.

Julius Werner ca52a25882 libpayload: arm64: Conform to new coreboot lib_helpers.h and assume EL2
This patch adds the new, faster architectural register accessors to
libpayload that were already added to coreboot in CB:27881. It also
hardcodes the assumption that coreboot payloads run at EL2, which has
already been hardcoded in coreboot with CB:27880 (see rationale there).
This means we can drop all the read_current/write_current stuff which
added a lot of unnecessary helpers to check the current exception level.

This patch breaks payloads that used read_current/write_current
accessors, but it seems unlikely that many payloads deal with this stuff
anyway, and it should be a trivial fix (just replace them with the
respective _el2 versions).

Also add accessors for a couple of more registers that are required to
enable debug mode while I'm here.

Ronald G. Minnich 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.

Nico Huber d44221f9c8 Move compiler.h to commonlib
Its spreading copies got out of sync. And as it is not a standard header
but used in commonlib code, it belongs into commonlib. While we are at
it, always include it via GCC's `-include` switch.

Some Windows and BSD quirk handling went into the util copies. We always
guard from redefinitions now to prevent further issues.

Jonathan Neuschäfer 6dff3fdd40 arch/riscv: Adjust compiler flags for scan-build
Clang doesn't understand -march=riscv64imac and -mcmodel=medany, so
don't use them when running the clang static analyzer. On the other
hand, __riscv and __riscv_xlen need to be defined in order to select
some macros in src/arch/riscv/include/arch/encoding.h. __riscv_flen
selects the floating-point paths in src/arch/riscv/misaligned.c.
-mabi is moved with -march for consistency.

A complete list of preprocessor definitions on RISC-V can be found at
https://github.com/riscv/riscv-toolchain-conventions#cc-preprocessor-definitions

With this commit, scan-build produces a useful result on RISC-V.

Marshall Dawson 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.

Some ACPI interfaces introduced by Chrome or coreboot do not
need drivers outside ChromeOS, for example Chrome EC or
coreboot table; or will be probed by direct ACPI calls (instead
of trying to find drivers by device IDs).

These interfaces should be set to hidden so non-ChromeOS systems,
for example Windows, won't have problem finding driver.

Interfaces changed:
- coreboot (BOOT0000), only used by Chrome OS / Linux kernel.
- Chrome OS EC
- Chrome OS EC PD
- Chrome OS TBMC
- Chrome OS RAMoops

BUG=b:72200466
BRANCH=eve
TEST=Boot into non-ChromeOS systems (for example Windows)
     and checked ACPI devices on UI.

Julius Werner 5d6593a43c arm64: Factor out common parts of romstage execution flow
The romstage main() entry point on arm64 boards is usually in mainboard
code, but there are a handful of lines that are always needed in there
and not really mainboard specific (or chipset specific). We keep arguing
every once in a while that this isn't ideal, so rather than arguing any
longer let's just fix it. This patch moves the main() function into arch
code with callbacks that the platform can hook into. (This approach can
probably be expanded onto other architectures, so when that happens this
file should move into src/lib.)

Tested on Cheza and Kevin. I think the approach is straight-forward
enough that we can take this without testing every board. (Note that in
a few cases, this delays some platform-specific calls until after
console_init() and exception_init()... since these functions don't
really take that long, especially if there is no serial console
configured, I don't expect this to cause any issues.)

Julius Werner 487f7f24a5 arm64: mmu: Spot check security state for TTB mapping
Since commit 372d0ff1d1 (arch/arm64: mmu: Spot check TTB memory
attributes), we already check the memory attributes that the TTB region
is mapped with to avoid configuration mistakes that cause weird issues
(because the MMU walks the page tables with different memory attributes
than they were written with). Unfortunately, we only checked
cachability, but the security state attribute is just as important for
this (because it is part of the cache tag, meaning that a cache entry
created by accessing the non-secure mapping won't be used when trying to
read the same address through a secure mapping... and since AArch64 page
table walks are cache snooping and we rely on that behavior, this can
lead to the MMU not seeing the new page table entries we just wrote).

This patch adds the check for security state and cleans up that code a
little.

Julius Werner e819c85760 arm64: Turn architectural register accessors into inline functions
Accesses to architectural registers should be really fast -- they're
just registers, after all. In fact, the arm64 architecture uses them for
some timing-senstive uses like the architectural timer. A read should be:
one instruction, no data dependencies, done.

However, our current coreboot framework wraps each of these accesses
into a separate function. Suddenly you have to spill registers on a
stack, make a function call, move your stack pointer, etc. When running
without MMU this adds a significant enough delay to cause timing
problems when bitbanging a UART on SDM845.

This patch replaces all those existing functions with static inline
definitions in the header so they will get reduced to a single
instruction as they should be. Also use some macros to condense the code
a little since they're all so regular, which should make it easier to
add more in the future. This patch also expands all the data types to
uint64_t since that's what the actual assembly instruction accesses,
even if the register itself only has 32 bits (the others will be ignored
by the processor and set to 0 on read). Arm regularly expands registers
as they add new bit fields to them with newer iterations of the
architecture anyway, so this just prepares us for the inevitable.

Julius Werner 0c5f61a01c arm64: Drop checks for current exception level, hardcode EL3 assumption
When we first created the arm64 port, we weren't quite sure whether
coreboot would always run in EL3 on all platforms. The AArch64 A.R.M.
technically considers this exception level optional, but in practice all
SoCs seem to support it. We have since accumulated a lot of code that
already hardcodes an implicit or explicit assumption of executing in EL3
somewhere, so coreboot wouldn't work on a system that tries to enter it
in EL1/2 right now anyway.

However, some of our low level support libraries (in particular those
for accessing architectural registers) still have provisions for
running at different exception levels built-in, and often use switch
statements over the current exception level to decide which register to
access. This includes an unnecessarily large amount of code for what
should be single-instruction operations and precludes further
optimization via inlining.

This patch removes any remaining code that dynamically depends on the
current exception level and makes the assumption that coreboot executes
at EL3 official. If this ever needs to change for a future platform, it
would probably be cleaner to set the expected exception level in a
Kconfig rather than always probing it at runtime.
