## Device specific stuff

# Wandboard
pacman -Sy uboot-wandboard
pacman -Sy firmware-imx
pacman -Sy firmware-brcm43xx
curl https://raw.githubusercontent.com/Freescale/meta-fsl-arm-extra/master/recipes-bsp/broadcom-nvram-config/files/wandboard/nvram.txt \
  > /lib/firmware/brcmfmac-sdio.txt
ln -s /lib/firmware/brcmfmac4329-sdio.bin /lib/firmware/brcmfmac-sdio.bin

## Set hostname

hostnamectl set-hostname wandboard

## Root fs

echo -e "/dev/root\t/\text4\tnoatime,discard,data=ordered\t0\t0" >>/etc/fstab

# Resize root mmc partition to fill entire storage area
# This only applies if you used an image that was not the same size as your mmc.

fdisk /dev/mmcblk0

# Print partition table, take note of partition 2 start sector
# p
# Delete the second partition /dev/mmcblk0p2
# d
# 2
# Create a new primary partition.
# n
# p
# 2
# <original p2 start sector>
# enter
#
# Save and exit fdisk:

reboot

## Colorful pacman output

sed -i 's/^#Color$/Color/' /etc/pacman.conf

## Update system

pacman -Syu

## Wireless

pacman -Sy iw wpa_supplicant
echo -e "ctrl_interface=/run/wpa-wlan0\nupdate_config=1" > /etc/wpa_supplicant/wpa_supplicant-wlan0.conf
systemctl enable wpa_supplicant@wlan0
systemctl enable dhcpcd@wlan0
# Read https://wiki.archlinux.org/index.php/WPA_Supplicant for details on setting up a network

## Bluetooth
# Replace systemd/script - it uses the wrong tty!
systemctl enable brcm43xx

## Set local timezone

timedatectl set-timezone America/Chicago
timedatectl set-local-rtc 0
timedatectl set-ntp 1

## Setup AUR support (and yaourt)

pacman -S --needed base-devel
sed -r -i 's/^#?MAKEFLAGS="-j.*/MAKEFLAGS="-j'`nproc`'"/' /etc/makepkg.conf
mkdir ~/build && \
  cd ~/build && \
  curl -O https://aur.archlinux.org/packages/pa/package-query/package-query.tar.gz && \
