From 170f2edadb5688989cbb1a7b899fb0a0615f78bd Mon Sep 17 00:00:00 2001 From: "Tan, Lean Sheng" Date: Fri, 27 Nov 2020 03:56:08 -0800 Subject: [PATCH] mb/intel/ehlcrb: Remove board ID detection via EC Since there is no EC support on EHL CRB, this patch removes board ID detection via EC (board_id.c & board_id.h) and its related files. Temporarily removes variant_memcfg_config function in romstage_fsp_param.c, will be added back when updating memory configs later.
