What's your yocto release / base kernel ? IF you happen to

Plan is to move to linux-yocto (currently using wrs). How do I configure it without using a defconfig?

Also, is it possible to use a .config rather than a defconfig? I've got a lot of stuff turned off to reduce the size of the kernel, but a defconfig doesn't quite do. For example, if I have

# CONFIG_USB_SERIAL is not set

in a defconfig, then this gets in to the .config at build time. However, this doesn't disable any dependencies that are enabled in linux-wrs. This means that modules for the likes of the ftdi and pl2303 USB serial devices are still included in the kernel image.

The use of a complete .config would stop this.
