#----------------------------------------------------------------------------------
# STANDARD SLUGOS DEFINITIONS
#----------------------------------------------------------------------------------
# The following must be set in the top level distro file:
#
#DISTRO_NAME
#DISTRO_TYPE
#ARM_INSTRUCTION_SET "arm" or "thumb"
#TARGET_OS "linux" or "linux-uclibc"

# The following may be overridden to make sub-versions

# The following need not be set, the defaults should be adequate
#USE_NLS = "no" or "yes"

# To make errors easier to identify:

# The following must not be changed.

# FULL_OPTIMIZATION
#    Optimization settings.  Os works fine and is significantly better than O2.

# We need to keep OABI compat for things like madwifi-ng.

#----------------------------------------------------------------------------------
# FEEDS
#  The FEED_URIS lines define where on the internet SlugOS looks for packages
#  when downloading new packages or updating existing packages.  Additional feeds
#  (such as a local feed) can be defined in local.conf
#----------------------------------------------------------------------------------

#----------------------------------------------------------------------------------
# FIRMWARE CONFIGURATION
#----------------------------------------------------------------------------------
# IMAGE BUILD OPTIONS
# -------------------
# CMDLINE* macros define the kernel command line.  CMDLINE_DEBUG is provided
# to enable/disable debugging in the distro.  Here noirqdebug is used to
# remove the messages about unhandled interrupts - people debugging interrupt
# issues in the kernel need to cancel this (set CMDLINE_DEBUG empty in local.conf)
CMDLINE_ROOT  = "root=/dev/mtdblock4 rootfstype=jffs2 rootflags=noatime rw init=/linuxrc"
CMDLINE_DEBUG = "noirqdebug"

# EXTRA PACKAGES
# --------------
# SlugOS builds an image with no extra packages - to add packages to the
# firmware include this file in a new 'distro' configuration file) and set
# the definition below to include the requirements.
# NOTE: as built this system will *not* be able to boot off anything other than
# the flash file system ('turnup' will not work).  You need to add the filesystem
# modules for your chosen root file system (and any others which will be used).
# See openslug.conf for a more full-featured system!
#
# Everything in this list gets added to the flash image, along with any RDEPENDS
# it has itself!
