soc/intel/alderlake: Inject CSE TS into CBMEM timestamp table
Get boot performance timestamps from CSE and inject them into CBMEM timestamp table after normalizing to the zero-point value. Although consumer CSE sku also supports this feature, it was validated on CSE Lite sku only. BUG=b:182575295 TEST=Able to see TS elapse prior to IA reset on Brya/Redrix 990:CSME ROM started execution 0 944:CSE sent 'Boot Stall Done' to PMC 88,000 945:CSE started to handle ICC configuration 88,000 (0) 946:CSE sent 'Host BIOS Prep Done' to PMC 90,000 (2,000) 947:CSE received 'CPU Reset Done Ack sent' from PMC 282,000 (192,000) 0:1st timestamp 330,857 (48,857) 11:start of bootblock 341,811 (10,953) 12:end of bootblock 349,299 (7,487) Signed-off-by: Bora Guvendik <bora.guvendik@intel.com> Change-Id: Idcdbb69538ca2977cd97ce1ef9b211ff6510a3f8 Reviewed-on: https://review.coreboot.org/c/coreboot/+/59507 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Tim Wawrzynczak <twawrzynczak@chromium.org>
