Disable "regular output" on GPIO-Pins 10 & 8

[runaway]

I want to use a power switch on my runeaudio-pi. This switch listens on two gpio-pins for the switch status. Since my wolfson audiocard occupies all gpio pins I am limited to using pins 10 & 8 for the switch, which the wolfson card gives acess to on their board. Problem: these pins are normally used for serialbus-infos, (Tx/Rx). These are obviously toggled during boot of the runeaudio system. My question is how to disable the serial port output to pins 8 and 10?
Thanks for the help, Stefan

Disable serial console:

(disable in /boot/cmdline.txt and in /etc/inittab )

In ArchLinux (RuneAudio), you need to remove references to ttyAMA0 in the file
/boot/config_linux-rune-rpi_3.12.13-rt21_wosa.txt (for Wolfson Audio Card)
and issue the following command:
systemctl disable serial-getty@ttyAMA0.service
(and/or)
systemctl disable agetty@ttyAMA0.service
And then reboot: to see whether it worked, use the following command:
cat /proc/cmdline [ | grep ttyAMA0]
- it should not return/find anything, meaning the procedure worked, and then you can use your serial link (Tx/Rx pins) as you like.

= this is what I did on my RPi + Wolfson system, where I use GPIO14 and GPIO15

Awesome, thx! Will try it.
