Kernel for Galaxy S24, rebased on CLO sources (WIP)
b30be4dc73
Both arm64 and powerpc do essentially the same FDT /chosen setup for kexec. The differences are either omissions that arm64 should have or additional properties that will be ignored. The setup code can be combined and shared by both powerpc and arm64. The differences relative to the arm64 version: - If /chosen doesn't exist, it will be created (should never happen). - Any old dtb and initrd reserved memory will be released. - The new initrd and elfcorehdr are marked reserved. - "linux,booted-from-kexec" is set. The differences relative to the powerpc version: - "kaslr-seed" and "rng-seed" may be set. - "linux,elfcorehdr" is set. - Any existing "linux,usable-memory-range" is removed. Combine the code for setting up the /chosen node in the FDT and updating the memory reservation for kexec, for powerpc and arm64, in of_kexec_alloc_and_setup_fdt() and move it to "drivers/of/kexec.c".

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.
