Linux 4.2 Kernel Gets Port To New Processor Architecture

The latest pull request to be submitted for Linux 4.2 is providing a new processor architecture port.

The new CPU port of the Linux kernel is to the Renesas H8/300 micro-controler. The H8 is a family of micro-controllers from Renesas Technology and the H8/300 uses an 32-bit CPU (though there's also versions of 8 and 16-bit, but they appear unsupported by this new port) designed for real-time control applications. The H8/300 has been around for a while and one of the many products its found in is the LEGO Mindstorms RCX. Up to now the Linux support for the H8 300 has been maintained out-of-tree.

This H8/300 architecture port of the Linux kernel has been in discussions for several months and has undergone twelve patch revisions so far for getting it into shape for mainline inclusion. The new port amounts to around 7,500 lines of new kernel code.

More details on the Renesas H8/300 CPU port for Linux 4.2 can be found via this pull request.
