The size of the cache-as-ram region required during bootblock

must add up to a power of 2.

Select this option to add a System Agent binary to
the resulting coreboot image.
Note: Without this binary coreboot will not work

The path and filename of the file to use as System Agent
binary.

default 0x100000
help
On Haswell systems the firmware image has to store a lot more
than just coreboot, including:
- a firmware descriptor
- Intel Management Engine firmware
- MRC cache information
This option allows to limit the size of the CBFS portion in the
firmware image.
config PRE_GRAPHICS_DELAY
int "Graphics initialization delay in ms"
default 0
help
On some systems, coreboot boots so fast that connected monitors
(mostly TVs) won't be able to wake up fast enough to talk to the
VBIOS. On those systems we need to wait for a bit before executing
the VBIOS.
