7073ec43b0 arch/riscv: Add common FDT build
Currently all platforms on RISC-V require a FDT.
The inclusion of the FDT is currently done in the platform Makefiles.
In order to factor out some common code this patch adds the inclusion
in the architecture Makefile. The FDT must be aligned to 8 byte
according to device tree spec. It avoids misaligned access.

b04ecb2a5f arch/x86: Enable support for IOAPIC devices
On platforms with multiple IOAPICs the GSI base must not be
linear, which is currently assumed by acpi_create_madt_ioapic_from_hw().

Integrate the existing struct device DEVICE_PATH_IOAPIC type and allow
to assign custom GSI bases for each IOAPIC. Write out the IOAPIC devices
into the MADT table if any.

For now, since no platform adds IOAPIC devices, the existing behaviour
remains the same. Allows to get rid of soc_get_ioapic_info().

0b617c9300 arch/riscv: Refactor SMP code
Currently only a fixed number of harts/cores can be detected.

This patch adds a Kconfig option which allows to detect the number of
harts at runtime if a SOC or mainboard has a scheme to do so.
As part of that patch SMP logic has been mostly moved to smp_resume,
since it is easier to debug issues at the time smp_resume is called
than it is at smp_pause, since the serial is usually not present at the
time of the first smp_pause call.

6c063250b5 arch/riscv: Allow adding OpenSBI as external blob
The reasoning is that even though vendors currently tend to open source
their OpenSBI implementation, they often do so in their own repository.
So instead of adding all possible source repositories as submodules, we
shall allow specifying a path to an already compiled OpenSBI ELF file.
This is similar of what we currently do on ARM64 with the BL31 binary.

b161d90f06 arch/x86: Configure EBDA through Kconfig
EBDA (Extended BIOS Data Area) is a memory area below 0xA0000 and
one of the default areas where OS will scan ACPI RSDP pointer from.

coreboot's default EBDA's starting address is 0xF6000, which is in
PAM (Programmable Attribute Map) F-segment's scope. For some platforms
without writeable PAM-F segment (e.g. some simics virtual platforms),
corboot's default EBDA is not writable.

Make DEFAULT_EBDA_LOWMEM, DEFAULT_EBDA_SEGMENT, DEFAULT_EBDA_SIZE
as Kconfig items so that coreboot's EBDA could be relocated to a
writable low memory place.

e169419946 arch/x86: Clarify help text for 64-bit support
The word "experimental" has been removed from the help text for
HAVE_X86_64_SUPPORT Kconfig. This is because the x86_64 architecture
has now been officially tested and enabled for several x86 SoC
platforms.

This work will provide us with the foundation we need to begin working
with Intel's next-generation SoC platform (which requires to support
64-bit mode of booting by default).

Therefore, we can now remove the word "experimental" from the
"HAVE_X86_64_SUPPORT" Kconfig help text.

TEST=Able to build and boot google/rex64 in 64-bit mode to ChromeOS.

4e00e6291a arch/io.h: Add port I/O functions to other architectures
The QEMU Bochs display driver and the QEMU Firmware Configuration
interface code (in the qemu-i440fx mainboard dir) were written for x86.
These devices are available in QEMU VMs of other architectures as well,
so we want to port them to be independent from x86.

The main problem is that the drivers use x86 port I/O functions to
communicate with devices over PCI I/O space. These are currently not
available for ARM* and RISC-V, although it is often still possible to
access PCI I/O ports over MMIO through a translator.

Add implementations of port I/O functions that work with PCI I/O space
on these architectures as well, assuming there is such a translator at a
known address configured at build-time.

628b8ed549 arch/arm64: Support FEAT_CCIDX
ARM SoC supports FEAT_CCIDX after ARMv8.3. The register field
description of CCSIDR_EL1 is different when FEAT_CCIDX is implemented.
If numsets and associativity from CCSIDR_EL1 are not correct, the system
would hang during mmu_disable().

Rather than assuming that FEAT_CCIDX is not implemented, this patch
adds a check to dcache_apply_all to use the right register format.

06b25c26a1 x86: Switch to protected_mode_call_1arg for correct argument passing
The payload execution process has been updated to utilize
protected_mode_call_1arg in order to guarantee proper handling of
function parameters.

The previous use of protected_mode_jump with a "jmp" instruction did
not allow for proper stack setup for argument passing, as the calling
convention was not aligned with the System V ABI calling convention.

This patch ensures that calling into the libpayload entry point using
protected mode is now aligned with the System V ABI calling convention.

This resolves an issue where retrieving the "pointer to coreboot tables"
from within the libpayload entry point was failing due to incorrect
argument passing.

7e3cabec51 arch/arm64/Makefile.mk: Unset toolchain vars for BL31
This change is for upcoming arm-trusted uprev commit.

TF-A refactors the toolchain detection in [1][2]. After that `AR`,
`CC`, `LD` and other toolchain variables have precedence over
`CROSS_COMPILE`.

Since ChromeOS build system also sets those toolchain variables when
building coreboot, it results that TF-A uses CrOS GCC instead of
coreboot SDK. It needs to unset those variables in order to make
`CROSS_COMPILE` effective.

TF-A upstream changes the default linker from BFD to GCC in [3].
Therefore, temporarily overriding LD as $(LD_arm64} to fix the below
build error.

aarch64-elf-gcc: error: unrecognized command-line option '--emit-relocs'

In addition, TF-A wrapped LD with single quotes to solve Windows path
issue[4]. On MT8173 platform, `--fix-cortex-a53-843419` is appended to
$(LD_arm64} for ERRATA_A53_843419. It results in the below build error.

/bin/sh: 1: --fix-cortex-a53-843419: not found

Since `--fix-cortex-a53-843419` is never passed to TF-A, simply extract
the LD command from $(LD_arm64) by $(word 1, $(LD_arm64)).
