Diogo Ivo says: ==================== Support ICSSG-based Ethernet on AM65x SR1.0 devices This series extends the current ICSSG-based Ethernet driver to support AM65x Silicon Revision 1.0 devices. Notable differences between the Silicon Revisions are that there is no TX core in SR1.0 with this being handled by the firmware, requiring extra DMA channels to manage communication with the firmware (with the firmware being different as well) and in the packet classifier. The motivation behind it is that a significant number of Siemens devices containing SR1.0 silicon have been deployed in the field and need to be supported and updated to newer kernel versions without losing functionality. This series is based on TI's 5.10 SDK [1]. The fifth version of this patch series can be found in [2]. Compared to the last version of the patch set there are only changes in patch 05/10, where the fields of a struct are now explicitly declared as __le32 so that we can properly interpret them. Both of the problems mentioned in v4 have been addressed by disabling those functionalities, meaning that this driver currently only supports one TX queue and does not support a 100Mbit/s half-duplex connection. The removal of these features has been commented in the appropriate locations in the code.

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.
