Where to add CONFIG_... things?

Hi,
I have suggestions to change my kernel config by adding lines like:

CONFIG_OMAP_IOMMU=y
CONFIG_OMAP_IOMMU_IVA2=y

Where is the place where I could add such lines in kernel sources?

I don't think you would do it in the actual source code. When compiling the kernel, there is typically a configuration file that gets used. Do a google search using "kernel configuration file" and see where that leads you. Also look at "make menuconfig"

Ok.

.config in main kernel sources directory.

Thanks for help.

EDIT:

I wanted to add that lines, but if I'm starting my compilation, new .config file is created:

scripts/kconfig/conf --silentoldconfig Kconfig
#
# configuration written to .config
#

I suppose that my .config file is not taken into account because of that --silentoldconfig. How could I change it?
