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. ME: Version: 13.5.0.7049 ME: HFSTS1 : 0x90006255 ME: HFSTS2 : 0x82100136 ME: HFSTS3 : 0x00000020 ME: HFSTS4 : 0x00004800 ME: HFSTS5 : 0x00000000 ME: HFSTS6 : 0x00400006 ME: Manufacturing Mode : YES ME: FW Partition Table : OK ME: Bringup Loader Failure : NO ME: Firmware Init Complete : YES ME: Boot Options Present : NO ME: Update In Progress : NO ME: D0i3 Support : YES ME: Low Power State Enabled : NO ME: CPU Replaced : YES ME: CPU Replacement Valid : YES ME: Current Working State : 5 ME: Current Operation State : 1 ME: Current Operation Mode : 0 ME: Error Code : 6 ME: CPU Debug Disabled : YES ME: TXT Support : NO Change-Id: Ic6b1c9410db8f06ac24fd997772b2ede04264bee Signed-off-by: Krishna Prasad Bhat <krishna.p.bhat.d@intel.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/40570 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Karthik Ramasubramanian <kramasub@google.com>
