Since the OP-TEE commit "plat-stm32mp1: scmi_server: default use OP-TEE
shared memory", integrated in OP-TEE 3.22.0-rc1, the default configuration
for STM32MP15x SoCs changes and CFG_STM32MP1_SCMI_SHM_SYSRAM is disabled
by default and the OP-TEE SMCI server uses OP-TEE native shared memory
registered by clients.
To be compatible with this configuration and the next OP-TEE versions,
this patch removes in the STM32MP15 SCMI device tree the SHMEM used by
OP-TEE SCMI and the associated reserved memory in the last 4KByte page
of SRAM.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
