From 82a3d1f81f8e401c6c34cba541970197aba2bb9a Mon Sep 17 00:00:00 2001 From: Igor Mammedov Date: Thu, 24 Aug 2017 18:31:32 +0200 Subject: [PATCH] alpha: replace cpu_alpha_init() with cpu_generic_init() cpu_alpha_init() used to provide default fallback if invalid (i.e. non existent) cpu_model were provided. dp264 machine provides its own default so sole user of fallback is [bsd|linux]-user targets which specifies 'any' cpu model that fallbacks to "ev67" in cpu_alpha_init(). Push fallback handling into alpha_cpu_class_by_name() and replace cpu_alpha_init() with cpu_generic_init().
