From 4ba66a9760722ccbb691b8f7116cad2f791cca7b Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Wed, 7 Mar 2018 22:23:24 +0100 Subject: arch: remove blackfin port The Analog Devices Blackfin port was added in 2007 and was rather active for a while, but all work on it has come to a standstill over time, as Analog have changed their product line-up. Aaron Wu confirmed that the architecture port is no longer relevant, and multiple people suggested removing blackfin independently because of some of its oddities like a non-working SMP port, and the amount of duplication between the chip variants, which cause extra work when doing cross-architecture changes.
