From: Pierre-Louis Bossart Date: Thu, 30 May 2019 11:50:11 +0000 (-0500) Subject: ASoC: Intel: use common helpers to detect CPUs X-Git-Tag: v5.15~5427^2~39^2~419 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=536cfd2f375d36f4316c0b93bb9e0eaf78e0ef6c;p=platform%2Fkernel%2Flinux-starfive.git ASoC: Intel: use common helpers to detect CPUs We have duplicated code in multiple locations (atom, machine drivers, SOF) to detect Baytrail, Cherrytrail and other SOCs. This is not very elegant, and introduces dependencies on CONFIG_X86 that prevent COMPILE_TEST from working. Add common helpers to provide same functionality in a cleaner way. This will also help support the DMI-based quirks being introduced to handle SOF/SST autodetection.
