Browsing thru the driver disassembly, I noticed that ARM gcc generated no code whatsoever for sh_eth_soft_swap() while building a little-endian kernel -- apparently __LITTLE_ENDIAN__ was not being #define'd, however it got implicitly #define'd when building with the SH gcc (I could only find the explicit #define __LITTLE_ENDIAN that was #include'd when building a little-endian kernel). Luckily, the Ether controller only doing big- endian DMA is encountered on the early SH771x SoCs only and all ARM SoCs implement EDMR.DE and thus set 'sh_eth_cpu_data::hw_swap'. But anyway, we need to fix the #ifdef inside sh_eth_soft_swap() to something that would work on all architectures...

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
