On Bay Trail systems the firmware image has to store a lot more
than just coreboot, including:
- a firmware descriptor
- Intel Trusted Execution Engine firmware
This option specifies the maximum size of the CBFS portion in the
firmware image.
config INCLUDE_ME

help
Build the TXE and descriptor.bin into the ROM image. If you want to use a
descriptor.bin and TXE file from the previous ROM image, you may not want
to build it in here.
config ME_PATH

depends on INCLUDE_ME
help
The path of the TXE and Descriptor files.
config LOCK_MANAGEMENT_ENGINE
bool "Lock TXE section"
default n
depends on INCLUDE_ME
help
The Intel Trusted Execution Engine supports preventing write accesses
from the host to the Management Engine section in the firmware
descriptor. If the ME section is locked, it can only be overwritten
with an external SPI flash programmer. You will want this if you
want to increase security of your ROM image once you are sure
that the ME firmware is no longer going to change.
If unsure, say N.
config ENABLE_BUILTIN_COM1
bool "Enable built-in legacy Serial Port"
help
The Baytrail SOC has one legacy serial port. Choose this option to
configure the pads and enable it. This serial port can be used for
the debug console.
