Manish V Badarkhe 3cb84a5425 plat/arm: Rentroduce tb_fw_config device tree
Moved BL2 configuration nodes from fw_config to newly
created tb_fw_config device tree.

fw_config device tree's main usage is to hold properties shared
across all BLx images.
An example is the "dtb-registry" node, which contains the
information about the other device tree configurations
(load-address, size).

Also, Updated load-address of tb_fw_config which is now located
after fw_config in SRAM.

Etienne Carriere 0754143ac9 stm32mp1: use last page of SYSRAM as SCMI shared memory
SCMI shared memory is used to exchange message payloads between
secure SCMI services and non-secure SCMI agents. It is mapped
uncached (device) mainly to conform to existing support in
the Linux kernel. Note that executive messages are mostly short
(few 32bit words) hence not using cache will not penalize much
performances.

Platform stm32mp1 shall configure ETZPC to harden properly the
secure and non-secure areas of the SYSRAM address space, that before
CPU accesses the shared memory when mapped non-secure.

This change defines STM32MP_SEC_SYSRAM_BASE/STM32MP_SEC_SYSRAM_SIZE and
STM32MP_NS_SYSRAM_BASE/STM32MP_NS_SYSRAM_SIZE.

Etienne Carriere e4ee1ab934 stm32mp1: disable neon in sp_min
Disable use of Neon VFP support for platform stm32mp1 when
building with SP_MIN runtime services as these can conflict with
non-secure world use of NEON support. This is preferred over a
systematic backup/restore of NEON context when switching
between non-secure and secure worlds.

When NEON support is disabled, this is done for both BL2 and BL32 as
build process uses common libraries built once for both binaries.

johpow01 dcbfbcb5de Workaround for Cortex A76 erratum 1800710
Cortex A76 erratum 1800710 is a Cat B erratum, present in older
revisions of the Cortex A76 processor core.  The workaround is to

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.

Manish V Badarkhe 158658704c plat/arm: Fix load address of TB_FW_CONFIG
Load address of tb_fw_config is incorrectly mentioned
in below device trees:
1. rdn1edge_fw_config.dts
2. tc0_fw_config.dts

Till now, tb_fw_config load-address is not being retrieved from
device tree and hence never exeprienced any issue for tc0 and
rdn1edge platform.

For tc0 and rdn1edge platform, Load-address of tb_fw_config should
be the SRAM base address + 0x300 (size of fw_config device tree)
Hence updated these platform's fw_config.dts accordingly to reflect
this load address change.
