[S] Change in flashrom[master]: flashrom: rename sb600spi.c to amd_spi.c

[XL] Change in flashrom[master]: ite_ecfw: Implement support for flashing ITE ECs found on TUXEDO laptops

Attention is currently required from: Nico Huber, Michał Żygowski, Paul Menzel. Michael Niewöhner has posted comments on this change. ( https://review.coreboot.org/c/flashrom/+/55715 ) Change subject: ite_ecfw: Implement support for flashing ITE ECs found on TUXEDO laptops ...................................................................... Patch Set 30: (1 comment) File ite_ecfw.c: https://review.coreboot.org/c/flashrom/+/55715/comment/07a44f68_aab65bf2 PS29, Line 696: } > Does it show something useful yet? AFAICS the firmware only returns one (hardcoded) byte 0xef [2], even though uEcFlash reads 3 bytes. When you read more you get unreliable results for the second and third byte ofc. I'm unsure what 0xef stands for tbh. One can read the eFlash id (RDID) via the DBGR interface like iteflash does (sending SPI cmd 0x9f). [1] My IT5570 on L140MU returns FF FF FE, which matches "EFLASH TYPE = 8315" in iteflash. I have no idea what that 8315 means. (KGD is "Known-Good-Die" by ESMT (vendor ID 0x8c) and/or Winbond (0xef).) The vendor id of my eFlash (0xff) matches "ITEID" in one of ITE's many flash tool implementations. Maybe they just forgot to update that hardcoded value to 0xff (=ITE)? Anyway, even uEcFlash is not doing anything with that value.
