From fd8773f9f544955f6f47dc2ac3ab85ad64376b7f Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Wed, 7 Mar 2018 21:21:59 +0100 Subject: arch: remove frv port The Fujitsu FRV kernel port has been around for a long time, but has not seen regular updates in several years and instead was marked 'Orphaned' in 2016 by long-time maintainer David Howells. The SoC product line apparently is apparently still around in the form of the Socionext Milbeaut image processor, but this one no longer uses the FRV CPU cores. This removes all FRV specific files from the kernel.
