It doesn't say which kernel all of those options apply to. If it's the
sunxi kernel, then you may be out of luck. If it's the mainline kernel,
which it probably is [1], don't you just edit the defconfig for the
kernel, find those options and set them, then recompile the kernel?
If I understand correctly, there is no need to modify a fex file, as
mainline kernels use the device tree model instead.
Why they weren't enabled in the first place though is a question to ask.

I'm sorry, but I think you didn't understand. I just want Parabola to
detect the GPIO pins, which is located in /dev/spidev* (virtually). GPIO
pins are peripherals.
And the reason is that I want to flash Libreboot on a ThinkPad *with the
BPi*, I do not want to flash Libreboot on the Pi (AFAIK no one has tried
that).

Hi everyone, I want to flash libreboot with my Banana Pi M1, but I
haven't found a way to enable the /dev/spidev* devices. I've tried
enabling spidev and spi-sun4i modules, but nothing. In some forums, it
tells me to edit the famous /boot/config.txt which is only available
for the RPi.
I've read http://linux-sunxi.org/SPIdev but I really do not know the
difference between "y" and "m" in kernels (I know that "m" stands for
"module"). If you can help me, I'd be very thankful.
IIRC y stands for "yes", assuming support is in the kernel, and y is to
enable that support. I think you are correct that m is for "module".
Have you tried UART connection?
Before arch linux arm supported the A10 olinuxino-lime, I got u-boot and
a kernel compiled with an arch linux rootfs, to put on an sdcard [1]. I
also did the same for an A13 tablet (although it had/needed proprietary
wifi drivers).
It was a long time ago, but I also had problems, so debugged using UART,
and can strongly recommend this for sunxi devices.
That said, I did not use libreboot, I used u-boot instead. Somebody had
already ported u-boot to those boards, so not much work was needed.
Sorry if I cannot be of any more help, I am by no means an expert,
Nowadays, I just install the arch linux arm image, and follow the
migration guide, which doesn't help much for debugging, but seems to work.
