However, the current KabyLake FSP published on GitHub doesn’t seem like it’s the right FSP for the SkyLake-U/KabyLake-U. If nothing else, there’s a problem with that FSP such that the signature in the FSP-M UPD header does not match the signature in the corresponding header files, so when the FSP 2.0 driver in coreboot goes to check that they are a match, execution dies right there.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><span style='font-family:"Courier New"'> if (upd->FspUpdHeader.Signature != FSPM_UPD_SIGNATURE)<o:p></o:p></span></p><p class=MsoNormal><span style='font-family:"Courier New"'> die("Invalid FSPM signature!\n");<o:p></o:p></span></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal style='text-indent:.5in'>(coreboot/src/drivers/intel/fsp2_0/memory_init.c, in function do_fsp_memory_init) <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>I don’t want to bypass that check in the code in case the FSP posted to GitHub isn’t the right FSP for this particular SoC…<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Obviously, somebody at Intel has the right FSP that works for these boards in order to validate that the coreboot implementation worked prior to upstreaming it to the repo.
