Andre Przywara 5a430c0219 rpi4/fdt: Move dtb_size() function to fdt_wrappers.h
Getting the actual size of a DTB blob is useful beyond the Raspberry Pi
port, so let's move this helper to a common header.

Alexei Fedorov 0aa9f3c0f2 TF-A: Redefine true/false definitions
This patch redefines 'true' and 'false' definitions in
'include/lib/libc/stdbool.h' to fix defect reported by
MISRA C-2012 Rule 10.1
"The expression \"0\" of non-boolean essential type is
being interpreted as a boolean value for the operator \"? :\"."

Manish V Badarkhe 2a0ef943b6 plat/arm, dts: Update platform device tree for CoT
Included cot_descriptors.dtsi in platform device tree
(fvp_tb_fw_config.dts).

Also, updated the maximum size of tb_fw_config to 0x1800
in order to accomodate the device tree for CoT descriptors.

Follow up patch will parse the device tree for these CoT descriptors
and fill the CoT descriptor structures at runtime instead of using
static CoT descriptor structures in the code base.

Masahiro Yamada e8ad6168b0 linker_script: move .rela.dyn section to bl_common.ld.h
The .rela.dyn section is the same for BL2-AT-EL3, BL31, TSP.

Move it to the common header file.

I slightly changed the definition so that we can do "RELA_SECTION >RAM".
It still produced equivalent elf images.

Please note I got rid of '.' from the VMA field. Otherwise, if the end
of previous .data section is not 8-byte aligned, it fails to link.

johpow01 0e0521bdfc Workaround for Neoverse N1 erratum 1800710
Neoverse N1 erratum 1800710 is a Cat B erratum, present in older
revisions of the Neoverse N1 processor core.  The workaround is to
set a bit in the ECTLR_EL1 system register, which disables allocation
of splintered pages in the L2 TLB.

Sandeep Tripathy 5eb16c4717 TF-A GIC driver: Add barrier before eoi
It is desired to have the peripheral writes completed to clear the
interrupt condition and de-assert the interrupt request to GIC before
EOI write. Failing which spurious interrupt will occurred.

A barrier is needed to ensure peripheral register write transfers are
complete before EOI is done.

GICv2 memory mapped DEVICE nGnR(n)E writes are ordered from core point
of view. However these writes may pass over different interconnects,
bridges, buffers leaving some rare chances for the actual write to
complete out of order.

GICv3 ICC EOI system register writes have no ordering against nGnR(n)E
memory writes as they are over different interfaces.

Hence a dsb can ensure from core no writes are issued before the previous
writes are *complete*.

Etienne Carriere 7d6fa6ecbe drivers/scmi-msg: smt entry points for incoming messages
This change implements SCMI channels for reading a SCMI message from a
shared memory and call the SCMI message drivers to route the message
to the target platform services.

SMT refers to the shared memory management protocol which is used
to get/put message/response in shared memory. SMT is a 28byte header
stating shared memory state and exchanged protocol data.

The processing entry for a SCMI message can be a secure interrupt
or fastcall SMCCC invocation.

SMT description in this implementation is based on the OP-TEE
project [1] itself based in the SCP-firmware implementation [2].

Etienne Carriere 6cc2c1cbed drivers/scmi-msg: support for reset domain protocol
Adds SCMI reset domain protocol support in the SCMI message drivers
as defined in SCMI specification v2.0 [1]. Not all the messages
defined in the specification are supported.

scmi_msg_get_rd_handler() sanitizes the message_id value
against any speculative use of reset domain ID as a index since by
SCMI specification, IDs are indices.

This implementation is based on the OP-TEE project implementation [2]
itself based on the SCP-firmware implementation [3] of the SCMI
protocol server side.

Etienne Carriere c9e8300012 drivers/scmi-msg: support for clock protocol
Adds SCMI clock protocol support in the SCMI message drivers as
defined in SCMI specification v2.0 [1] for clock protocol messages.

Platform can provide one of the plat_scmi_clock_*() handler for the
supported operations set/get state/rate and others.

scmi_msg_get_clock_handler() sanitizes the message_id value
against any speculative use of clock ID as a index since by
SCMI specification, IDs are indices.

This implementation is based on the OP-TEE project implementation [2]
itself based on the SCP-firmware implementation [3] of the SCMI
protocol server side.

Etienne Carriere 75366ccd9b drivers/scmi-msg: driver for processing scmi messages
This change introduces drivers to allow a platform to create a basic
SCMI service and register handlers for client request (SCMI agent) on
system resources. This is the first piece of the drivers: an entry
function, the SCMI base protocol support and helpers for create
the response message.

With this change, scmi_process_message() is the entry function to
process an incoming SCMI message. The function expect the message
is already copied from shared memory into secure memory. The message
structure stores message reference and output buffer reference where
response message shall be stored.

scmi_process_message() calls the SCMI protocol driver according to
the protocol ID in the message. The SCMI protocol driver will call
defined platform handlers according to the message content.

This change introduces only the SCMI base protocol as defined in
SCMI specification v2.0 [1]. Not all the messages defined
in the specification are supported.

The SCMI message implementation is derived from the OP-TEE project [2]
itself based on the SCP-firmware implementation [3] of the SCMI protocol
server side.

Varun Wadekar fbc44bd1bb Prevent RAS register access from lower ELs
This patch adds a build config 'RAS_TRAP_LOWER_EL_ERR_ACCESS' to set
SCR_EL3.TERR during CPU boot. This bit enables trapping RAS register
accesses from EL1 or EL2 to EL3.

RAS_TRAP_LOWER_EL_ERR_ACCESS is disabled by default.
