From 34c30565b0ef3b1ff79943768ecc2f4012bf6b86 Mon Sep 17 00:00:00 2001 From: Marshall Dawson Date: Tue, 16 Jul 2019 15:18:00 -0600 Subject: soc/amd/picasso: Update CPU support Change the Stoney Ridge ID to Picasso. Rename family 15h. Get the number of cores/threads from CPUID as all D18 registers are new.
