From ed3496730322286370b956e3eeb038ee56a41c74 Mon Sep 17 00:00:00 2001 From: Krishna Prasad Bhat Date: Tue, 21 Apr 2020 19:09:43 +0530 Subject: [PATCH] soc/intel/jasperlake: Add function to display ME firmware status info Add function to display ME Host Firmware Status registers. Make use of print_me_fw_version() from CSE lib to print ME firmware version information. Add manufacturing mode field in HFSTS1 register for JSL in place of, spi_protection_mode in TGL. BUG=None BRANCH=None TEST=Build and boot jslrvp. In coreboot logs, ME info can be seen.
