I first tried setting this in freemangordons-linux-n900/.config:
Code:
CONFIG_RFKILL=1
CONFIG_RFKILL_REGULATOR=m
But it got overwritten during the run of build-kernel.sh.

Normally you should use

Code:

CONFIG_RFKILL=y

to build it into the kernel, or

Code:

CONFIG_RFKILL=m

to build it as a module.

It sounds like it built it as a module if you've got an rfkill.ko. I'm not sure if that was what you desired.

You also need to create a U-Boot compatible kernel image and initrd. initrd might not be necessary but I always rebuild it to ensure that everything is kept in step. You can do this either on the device or in a QEMU chroot.

Code:

# KERNELRELEASE=3.18.0-rc6+
# mkimage -A arm -O linux -T kernel -C none -a 80008000 -e 80008000 -n $KERNELRELEASE -d /boot/zImage-$KERNELRELEASE /boot/uImage-$KERNELRELEASE
# update-initramfs -c -k $KERNELRELEASE

Obviously you'll want to substitute the value of KERNELRELEASE for the name of your kernel release. If you grabbed my scripts after 7th October then update-initramfs will create the uInitrd image automatically (thanks to sim6!) otherwise you will need to manually create it:

Code:

# mkimage -A arm -O linux -T ramdisk -C none -a 0 -e 0 -n initramfs -d /boot/initrd.img-$KERNELRELEASE /boot/uInitrd-$KERNELRELEASE

If you're setting up a new kernel release remember to update U-Boot too.
