From a89988a6e00c5a099ee23619cd91dc8dc7ec9328 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Wed, 19 Apr 2017 13:19:00 +0200 Subject: nios2: Add NIOS2_ARCH_REVISION to select between R1 and R2 Allow user to select between Nios2 R1 and R2. Since R1 and R2 are not binary compatible, we cannot have a single kernel binary and there is no point in having DT property for discerning these two.
