Mainline Linux tree for various devices, only for fun :)

The remoteproc core creates certain standard debugfs entries, that does not give a whole lot of useful information for the PRUs. The PRU remoteproc driver is enhanced to add additional debugfs entries for PRU. These will be auto-cleaned up when the parent rproc debug directory is removed. The enhanced debugfs support adds two new entries: 'regs' and 'single_step'. The 'regs' dumps out the useful CTRL sub-module registers as well as each of the 32 GPREGs and CT_REGs registers. The GPREGs and CT_REGs though are printed only when the PRU is halted and accessible as per the IP design. The 'single_step' utilizes the single-step execution of the PRU cores. Writing a non-zero value performs a single step, and a zero value restores the PRU to execute in the same mode as the mode before the first single step. (note: if the PRU is halted because of a halt instruction, then no change occurs). Logic for setting the PC and jumping over a halt instruction shall be added in the future.

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.
