drivers: imx: dcp: workaround DCP errata 051292

The internal boot ROM should reset the DCP controller prior jumping to
bootloader execution. The current boot ROM implementation does not
assert a DCP reset.

To mitigate the issue, users can implement a DCP reset by setting
SFTRST[31] and CTRL_CLKGATE[30] bits in the DCP_CTRL_SET registers.

drivers: imx_snvs: re-work security state for imx8m platforms

The current implementation of snvs_get_security_cfg() for
imx8m platforms includes the read of SYS_SECURE_BOOT bit.
This fourth bit shows if the board boots from internal
ROM. This bit will reset to 1 for a board in the field
and 0 for a test chip.

The read of this bit is out of scope of the snvs_get_security_cfg()
purpose which is to return the system security configuration.
The SYS_SECURE_BOOT bit (msb) can be discarded.

plat-sam: add timer clock driver

Add support for the TCB block that are present on the samad2. This
series add support for the TCB as a time source and register it using
REGISTER_TIME_SOURCE(). Moreover, on Linux, the tick is done using the
TCB since the sama5d2 does not have the ARM architected timers. Since
the time source used for the tick clocksource is probed early in the
boot process, the SCMI clock support which uses a platform driver is
not yet probed and thus the TCB can't be probe properly. To workaround
that problem, this driver enables the TCB clocks and the Linux
device-tree is modified to use "fixed-clock" clock instead of the TCB
SCMI ones.

drivers: scmi-msg: add SCMI MSG message protocol

Implements MSG header protocol to handle SCMI messages. MSG header
protocol was introduced in Linux kernel v5.15 [1]. It relies on normal
cached shared memory buffer using a 32bit header followed by the SCMI
message payload.

To support this message interface, the SCMI PTA defines a new capability
and a new command. Capability PTA_SCMI_CAPS_MSG_HEADER allows client and
service to negotiate the desired transport configuration. Command
PTA_SCMI_CMD_PROCESS_MSG_CHANNEL allows client to request processing
of a message sent based on that message exchange protocol.

Platforms shall enable configuration switch CFG_SCMI_MSG_SHM_MSG to have
their SCMI service supporting that communication protocol.
