From 6ee716e863117246d453e573d1a128da28b62cb7 Mon Sep 17 00:00:00 2001 From: Subrata Banik Date: Thu, 8 Feb 2018 16:50:21 +0530 Subject: drivers/intel/fsp2_0: Remove fsp_find_smbios_memory_info() from FSP2.0 driver As per FSP 2.0 specification and FSP SOC integration guide, its not expected that SMBIOS Memory Information GUID will be same for all platform. Hence fsp_find_smbios_memory_info() function inside common/driver code is not generic one. Removing this function and making use of fsp_find_extension_hob_by_guid() to find SMBIOS Memory Info GUID from platform code as needed.
