Nevermind, I forgot to add the OBB offset. 0xebeffc is correct.

I used this as workaround:
https://review.coreboot.org/c/coreboot/+/32327
It requires that you put the CBFS at the end of
@coreboot.org

Apollolake should work with:
CONFIG_CBFS_LOCATION=0xfffb1000
# CONFIG_HARDWARE_IRQ is not set
That's what I use for SeaBIOS as a legacy boot payload on ChromeOS devices, but
the CBFS address will be the same
Apollolake should work with:
CONFIG_CBFS_LOCATION=0xfffb1000
# CONFIG_HARDWARE_IRQ is not set
That's what I use for SeaBIOS as a legacy boot payload on ChromeOS devices,
but the CBFS address will be the same if using upstream coreboot
