# This script must be *sourced* from a Bourne-compatible shell in order to
# function. Nothing will happen if you execute it.
#
# Source a compiler-specific setup script for proper functionality. This is
# only a base script and does not suffice for kernel building without the
# flags that compiler-specific scripts append to kmake_flags.

#### CONFIGURATION ####

# Kernel name
kernel_name="Artemis"

# Defconfig name
defconfig="artemis_coral_defconfig"

# Target architecture
arch="arm64"

# Base kernel compile flags (extended by compiler setup script)
kmake_flags=(
	-j"$(nproc --all)"

# Initialize kernel

# Show an informational message

    echo -e "\e[1;32m$1\e[0m"
}

# Go to the root of the kernel repository repository
function croot() {
