The main and bulk of the addition this time is the support for the Arm reference Morello System Development Platform (SDP). The Morello architecture is an experimental extension to Armv8.2-A, enhancing the AArch64 execution state with capabilities for fine-grained memory protection and scalable software compartmentalization. However these changes doesn't add any of the support for security enhancements. This is mainly adding device tree support for Morello SDP. The platform iteslf is shipped with ACPI firmware. However, since the ACPI bindings for GPU, DPU, I2C, I2S,..etc are not well defined or not provided in the shipped ACPI firmware, there is a need for the device tree as alternative for the developers focusing on those features. The CPU is called rainier, the architecture is Morello and the platform is Morello SDP board. There is FVP equivalent of the same though they are not completely in feature parity with the real hardware. These changes provide the initial support for Morello SDP and FVP platforms. Apart from this, we have an update to add support for secondary cores on Corstone1000 FVP platform. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEunHlEgbzHrJD3ZPhAEG6vDF+4pgFAmfG0LIACgkQAEG6vDF+ 4phFpg/8D35cH6WWpfWWp0L3EILUVUcWRn0X0a4UJ7z2cl4UMn+cu7h2mzk6rT16 fCVj0Sjuek4AZgVpKT8+3A+GugRAIrmq1teRjfcu34yQFyGh/M95IhAs1ym0RQAN r6Ox0dCjHJc78tQ6zstLElbkINnf9FtrXjmOCeu8nNOkWODupDuLwC/sROavHXSD Yr6+ACCMBvfAIVQUFa1tC1YOvJH/+wKAjISVFJoB7hNG/VqLLEQNQ15HH/Gp97Vn 18oj5471GyIsKXiT2a3hnitDKfnRGnxLVRxSOEFGVR8n0D+HNphYQi11fi1CSkio HI6WDa3m1QP7CGlIW7PD+qClT7djNLUjcQglIF4+SV3NZWotGRRN6Uk7Bq+G24cS jFlXVy3iTfdGwvsnRU6S3WOdHTfjxOeJN6Bei9K262LUkCCl/t7M0q1EKu9twOY+ L0AZvk+g2kqm64KbxHxrHJYTE64ykpw6AnO1vXIM5xR1ov1/XVrzPTPfIIgI4Tb4 r99iIxhThXYe/bJ4yW4JKdW7CG6ZeyCVeIV1/MkhztlnsnR4O5EA8orEntQUdLOY VB/bHwVWCwvpSGmc928cxVUbfHfq/wyEwYBnEmxclAHug8mcSCgPtH52fhB69VWS uZAth1lqztgxS6kKN6TzeYvH2gxTeN5v+DWUgrktNOzIsAFTH4I= =QVaZ -----END PGP SIGNATURE----- gpgsig -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEiK/NIGsWEZVxh/FrYKtH/8kJUicFAmfJwy4ACgkQYKtH/8kJ UifGKRAA3Ke0JZLQSnnaSxTMctu+1CqT14m+sZ4ohVmncRPpG6v2mBPIxqxm1ivC X1fS2DJOO6/bASyhG9p05psW3zSyWNlsppiw3Sc5GtpuqBOPGbeTcA6WVT0TnMAy KrAlmeisql+SBKBNGkv0XW58fAbqeYCR/hPthQoqgHpWMON8lBMQvnx+JiH7IzTH /CYt1Fkqm0L1O4vz0lUfdjhdJ79eqvHpkvpdaNZK3mwPe49WVS4hTrgfJeq8B8Pp Z0pqmXTIeVfrc1aSKCPoOLNys8vxhTjazXzfto7hCahlUWNWCoPpUryK7MA6qo5f aOKP8AwsZhJ0tr4xf1u1kYYcjUDI7sYSTi9g/4oLuTjXTCnmXMIZWO5/fOBn574i mx3UK7UD6n/PhNWzgSbJGzWtPzOcaMycvDKLbpuU2UT1YRVUegpoecPApicntt0a IfBTEgWvLkpjgeP0AODqiuM26xWbfxdrd9iH9JIIwsoKnHO86/8QlNBqLB9+fHhZ 9FhAs48Y+C7B4DUOUIXHLD8TYD3zhIjM/sE+BJVGUQvtiFqBgfC9/rZNMMMwxsV5 jVnzSGbFO0RKSQOJr27lcydRICGaeINmEI+wKVJuQFutAtXf9p9jCbHi744Rz0no QSnwB+5p+hZLb9tx+DkIakG/IwscvLbg86/WV3L/IjLV+imHVv4= =Pf5p -----END PGP SIGNATURE----- Merge tag 'juno-updates-6.15' of https://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into soc/dt Armv8 FVP/Vexpress/Juno updates for v6.15 The main and bulk of the addition this time is the support for the Arm reference Morello System Development Platform (SDP).

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 reStructuredText 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.
