8e96801aa6 firmware: scmi: add multi-channel support
Adds resources for SCMI protocols to possibly use a dedicated SCMI
channel instead of the default channel allocated by the SCMI agent
during initialization. As per DT binding documentation, some SCMI
transports can define a specific SCMI communication channel for
given SCMI protocols. It allows SCMI protocols to pass messages
concurrently each other.

This change introduces new scmi agent uclass API function
devm_scmi_of_get_channel() for SCMI drivers probe sequences to get
a reference to the SCMI channel assigned to its related SCMI protocol.
The function queries the channel reference to its SCMI transport driver
through new scmi agent uclass operator .of_get_channel that uses Device
Tree information from related SCMI agent node.

Operator .of_get_channel returns a reference to the SCMI channel
assigned to SCMI protocol used by the caller device. SCMI transport
drivers that do not support multi-channel are not mandated to register
this operator. When so, API function devm_scmi_of_get_channel() returns
NULL and SCMI transport driver are expected to retrieve by their own
means the reference to the unique SCMI channel, for example using
platform data as these drivers currently do in U-Boot source tree.

8bcb1b4898 firmware: scmi: prepare scmi uclass API to multi-channel
Changes SCMI driver API function devm_scmi_process_msg() to add
an SCMI channel reference argument for when SCMI agent supports
SCMI protocol specific channels. First argument of devm_scmi_process_msg()
is also change to point to the caller SCMI protocol device rather
than its parent device (the SCMI agent device).

The argument is a pointer to opaque struct scmi_channel known from
the SCMI transport drivers. It is currently unused and caller a pass
NULL value. A later change will enable such support once SCMI protocol
drivers have means to get the channel reference during initialization.

593eac9805 firmware: scmi: optee: use TEE shared memory for SCMI messages
Changes implementation when using TEE dynamically allocated shared
memory to synchronize with the Linux implementation where the legacy
SMT protocol cannot be used with such memory since it is expected from
device mapped memory whereas OP-TEE shared memory is cached and
hence should not be accessed using memcpy_toio()/memcpy_fromio().

This change implements the MSG shared memory protocol introduced
in Linux [1]. The protocol uses a simplified SMT header of 32bit
named MSG_SMT to carry SCMI protocol information and uses side channel
means to carry exchanged buffer size information, as TEE invocation API
parameters when used in the SCMI OP-TEE transport.

1e578ed20c sandbox: Add support for Address Sanitizer
Add CONFIG_ASAN to build with the Address Sanitizer. This only works
with the sandbox so the config is likewise dependent. The resulting
executable will have ASAN instrumentation, including the leak detector
that can be disabled with the ASAN_OPTIONS environment variable:

   ASAN_OPTIONS=detect_leaks=0 ./u-boot

Since u-boot uses its own dlmalloc, dynamic allocations aren't
automatically instrumented, but stack variables and globals are.

Instrumentation could be added to dlmalloc to poison and unpoison memory
as it is allocated and deallocated, and to introduce redzones between
allocations. Alternatively, the sandbox may be able to play games with
the system allocator and somehow still keep the required memory
abstraction. No effort to address dynamic allocation is made by this
patch.

The config is not yet enabled for any targets by default.

99e2fbcb69 linker_lists: Rename sections to remove . prefix
Rename the sections used to implement linker lists so they begin with
'__u_boot_list' rather than '.u_boot_list'. The double underscore at the
start is still distinct from the single underscore used by the symbol
names.

Having a '.' in the section names conflicts with clang's ASAN
instrumentation which tries to add redzones between the linker list
elements, causing expected accesses to fail. However, clang doesn't try
to add redzones to user sections, which are names with all alphanumeric
and underscore characters.

The commit b583348ca8 ("image: fit: Align hash output buffers") places
the hash output buffer at the .bss section. However, AST2600 by default

We need to move the .bss section out of the SPL body to the DRAM space,
where hash output can be written to. This patch includes:
 - Define the .bss section base and size
 - A new SPL linker script is added with a separate .bss region specified
 - Enable CONFIG_SPL_SEPARATE_BSS kconfig option
