This adds initial support for the Marvell PXA1908 SoC and "samsung,coreprimevelte", a smartphone using the SoC. *Important note*: There is a regression on all of the v6.16 RCs where the board does not boot unrelated to the patches in this set. See: https://lore.kernel.org/regressions/3367665.aeNJFYEL58@radijator/ USB works and the phone can boot a rootfs from an SD card, but there are some warnings in the dmesg: During SMP initialization: [ 0.006519] CPU features: SANITY CHECK: Unexpected variation in SYS_CNTFRQ_EL0.

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.
