From 0f718312f1b57ec300b7486c95e53562be5a2325 Mon Sep 17 00:00:00 2001 From: Karthikeyan Ramasubramanian Date: Wed, 3 Jul 2019 13:02:37 -0600 Subject: soc/intel/common: Add SOC specific function to get XHCI USB info It feels appropriate to define SoC specific XHCI USB info in SoC specific XHCI source file and an API to get that information instead of defining it in elog source file. This will help in other situations where the information is required. BUG=None BRANCH=None TEST=Boot to ChromeOS.
