Re: [coreboot] Can't disable CONFIG_ENABLE_FSP_FAST_BOOT flag on Intel Baytrail platform

2017-12-13 Thread Naveed Ghori
Nico, I faced this same thing earlier I believe. The reason I disabled it was to stop coreboot from writing to the flash chip. I was advised to turn off CONFIG_ENABLE_FSP_FAST_BOOT and this worked for the flash but had this side affect. Garrett, Are you disabling it for the same reason?

-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 According to Positive Technologies, on Skylake and higher (like the Purism machines) the kernel loads the BUP, and the HAP bit only disables the normal userspace processes [1]. What proof do you have that the kernel itself is halted? [1]
