Check if certain sections are still required in bootstrap

[jweisz]

It's unclear if we still need to do these operations in bootstrap.

1. Don't install on armv6l? I'm not even sure where this came from 🤷

#----don't install on an armv6l, it's not supported
CPUARCH=$(lscpu | grep Arch | cut -d':' -f2 | awk '{$1=$1};1')
if [ "$CPUARCH" = 'armv6l' ];
   then
      echo "ARMv6 is not supported for TJBot due to software availability on this processor architecture. Please use another Raspberry Pi model."
      exit 1
else
   echo "$CPUARCH processor architecture supported. Proceeding with setup."
fi

2. This is a very old version of Raspian. At this point we might want to bump the minimum version to bookworm (12).

#----raspian versions older than jessie (8) won't work
RASPBIAN_VERSION_ID=$(cat /etc/os-release | grep VERSION_ID | cut -d '"' -f 2)
if [ "$RASPBIAN_VERSION_ID" -lt 8 ]; then

3. Do we need to install these additional packages? These might all be present in a vanilla install of Raspian at this point.

#----install additional packages
echo ""
echo "Installing additional software packages [apt-get install libasound2-dev libportaudio0 libportaudio2 libportaudiocpp0 porta
udio19-dev]"
apt-get install -y libasound2-dev libportaudio0 libportaudio2 libportaudiocpp0 portaudio19-dev

4. Is all of this necessary anymore to enable the Pi camera? Also, is it specific to RPi 3/4 or does it need to be done on an RPi 5?

#----enable camera on raspbery pi
echo ""
echo "If your Raspberry Pi has a camera installed, TJBot can use it to see."
read -r -p "Enable camera? [y/N] " choice </dev/tty
case "$choice" in
    "y" | "Y")
        if grep "start_x=1" /boot/config.txt
        then
            echo "Camera is already enabled."
        else
            echo "Enabling camera."
            if grep "start_x=0" /boot/config.txt
            then
                sed -i "s/start_x=0/start_x=1/g" /boot/config.txt
            else
                echo "start_x=1" | tee -a /boot/config.txt >/dev/null 2>&1
            fi
            if grep "gpu_mem=128" /boot/config.txt
            then
                :
            else
                echo "gpu_mem=128" | tee -a /boot/config.txt >/dev/null 2>&1
            fi
        fi
        ;;
    *) ;;
