Arm Juno fix for v5.17 Just a single fix to address coherency issue reported[1] by removing the GICv2m address from the DMA ranges as it loose coherency if mapped as cacheable at the SMMU due to the attribute combining rules. The GICv2m range is normally programmed for Device memory attributes.

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.
