The good news is that cbfstool now reports a non-zero mrc.cache, the bad news is it doesn't make any difference. cbmem -c reports Updating MRC cache data. No FMAP found at ffe70000. FMAP: area RW_MRC_CACHE not found find_current_mrc_cache_local: No valid MRC cache found. SF: Detected W25Q64 with page size 1000, total 800000 Need to erase the MRC cache region of -1 bytes at 0011037f SF: Erase offset/length not multiple of erase size Finally: write MRC cache update to flash at 0011037f ICH SPI: Data transaction error SF: Failed to send write command (1 bytes): -1 SF: Winbond Page Program failed
CONFIG_CHROMEOS=y You have that option enabled. That's why you are seeing fmap calls. Therefore, it is not using the mrc.cache cbfs file. There's also the fact that certain variables are not initialized properly and thinking the callee will initialize them. cache_base should be set to NULL in update_mrc_cache() before calling get_mrc_cahce_region(). You'll see more enlightening messages. That, or ensure get_mrc_cache_region NULL's out the parameter. In short, don't enable CONFIG_CHROMEOS.
Menuconfig enables it by default, and there is no option to uncheck. If I set it to 'n' or comment in .config I get: build/generated/crt0.romstage.o: In function `main': /home/john/coreboot/src/mainboard/samsung/lumpy/romstage.c:215: undefined reference to `save_chromeos_gpios' /home/john/coreboot/src/mainboard/samsung/lumpy/romstage.c:362: undefined reference to `init_chromeos' build/northbridge/intel/sandybridge/mrccache.romstage.o: In function `get_mrc_cache_region':

Fantastic. In src/mainboard/samsung/lumpy/Kconfig remove 'select CHROMEOS'. You'll need to do a 'make oldconfig' then rebuild. Fwiw, you can't set it to 'n'. It needs to be '# CONFIG_CHROMEOS is not set'. But since you did set it to 'n' the dependency object files weren't included in the link. Anyway, do a clean build after removing 'select CHROMEOS'. hth. -Aaron
Okay. We are getting a bit further along now but: CC cbfs/fallback/coreboot_ram.debug build/generated/coreboot_ram.o: In function `acpi_create_gnvs': /home/john/coreboot/src/mainboard/samsung/lumpy/acpi_tables.c:102: undefined reference to `chromeos_init_vboot' collect2: error: ld returned 1 exit status make: *** [build/cbfs/fallback/coreboot_ram.debug] Error 1
Try the following patch:
diff --git a/src/vendorcode/google/chromeos/gnvs.h b/src/vendorcode/google/chrom index 00fe443..5384423 100644 --- a/src/vendorcode/google/chromeos/gnvs.h +++ b/src/vendorcode/google/chromeos/gnvs.h @@ -61,9 +61,13 @@ typedef struct { // dbe } __attribute__((packed)) chromeos_acpi_t;

#endif
Or wrap the call in lumpy/acpi_tables.c with '#if CONFIG_CHROMEOS/#endif'.
Okay, that worked, but cold reboot takes 5 secs to SeaBIOS, warm reboot is instantaneous. cbmem -c output looks pretty healthy to me. I'll attach it anyway. What do you think?
