#@TYPE: Distribution
#@NAME: SlugOS
#@DESCRIPTION: SlugOS Linux Distribution for the NSLU2

# WARNING: this file should not be used directly, use one of
# the supported slugos-derived distributions instead:

# Explanation of the naming
#
# slugos - the base distro configuration for an NSLU2
# slugos-[bl][at][gu] - a specific configuration encoded as follows:
#
#  b or l - big or little endian
#
#  a or t - ARM or Thumb instructions in the low level libraries
#         set ARM_INSTRUCTION_SET to match
#
#  g or u - glibc or uclibc libc implementation
#         set TARGET_OS to match
#

#----------------------------------------------------------------------------------
# STANDARD SLUGOS DEFINITIONS
#----------------------------------------------------------------------------------
# The following must be set in the top level distro file:
#
#DISTRO_NAME
#DISTRO_TYPE

# The following may be overridden to make sub-versions
SLUGOS_VERSION = "4.3"
DISTRO_REVISION ?= ""
DISTRO_VERSION ?= "${SLUGOS_VERSION}${DISTRO_REVISION}-${DISTRO_TYPE}"
# For release (only):
# DISTRO_FEED ?= "${SLUGOS_VERSION}-${DISTRO_TYPE}"
DISTRO_FEED ?= "unstable"

SLUGOS_DISTRO ?= "slugos"

IMAGE_BASENAME = "${SLUGOS_DISTRO}"

# The following must also be set, they define the basic format of the build
#
#ARM_INSTRUCTION_SET "arm" or "thumb"
#TARGET_OS "linux" or "linux-uclibc"

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

# To make errors easier to identify:
DISTRO_NAME ?= "INVALID-${SITEINFO_ENDIANESS}-${ARM_INSTRUCTION_SET}-${TARGET_OS}"
DISTRO_TYPE ?= "INVALID"

# The following must not be changed.
TARGET_FPU = "soft"

# glib-2.0 builds require USE_NLS to be overridden
USE_NLS_glib-2.0 = "yes"

# FULL_OPTIMIZATION
#    Optimization settings.  Os works fine and is significantly better than O2.
#    The other settings are somewhat arbitrary.  The optimisations chosen here
#    include the ones which 'break' symbolic debugging (because the compiler does
#    not include enough information to allow the debugger to know where given
#    values are.)  The -fno options are an attempt to cancel explicit use of space
#    consuming options found in some packages (this isn't a complete list, this is
#    just the ones which package writers seem to know about and abuse).
FULL_OPTIMIZATION = "-Os -fomit-frame-pointer -frename-registers \
	-fno-unroll-loops -fno-inline-functions \
	-fweb -funit-at-a-time"

#----------------------------------------------------------------------------------
# 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
#----------------------------------------------------------------------------------
# Add to the user's feeds from local.conf (there may be none).
# In general slugos-[bl][at][gu] is sufficient to identify a set of packages which
# will work on any derived distro.  The slugos-???.conf files set the FEED_URIS to
# an appropriate ipkg.nslu2-linux.org default if nslu2-linux is actually building
# such a feed:
#
#FEED_URIS_append += "cross##http://ipkg.nslu2-linux.org/feeds/${SLUGOS-foo}/cross/${DISTRO_FEED}"
#FEED_URIS_append += "native##http://ipkg.nslu2-linux.org/feeds/${SLUGOS-foo}/native/${DISTRO_FEED}"
#
# When such a feed exists the corresponding 'unstable' feed will normally also
# exist - the packages in unstable are the latest but very unlikely to be the
# greatest.  Use at your own risk!
# 
#FEED_URIS_append += "unstable_cross##http://ipkg.nslu2-linux.org/feeds/${SLUGOS-foo}/cross/unstable"
#FEED_URIS_append += "unstable_native##http://ipkg.nslu2-linux.org/feeds/${SLUGOS-foo}/native/unstable"

#----------------------------------------------------------------------------------
# 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_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!
SLUGOS_EXTRA_RDEPENDS ?= ""

#----------------------------------------------------------------------------------
# PACKAGE VERSION CONTROL
#----------------------------------------------------------------------------------
# Define how to bootstrap the system - we need cross compilers.  It is also
# necessary to define which gets generated first, glibc or the kernel, and
# this is done by selecting the provider of libc (in this case it needs the
# kernel, so there has to be a non-libc gcc to build the kernel!)
