#@DESCRIPTION: SlugOS Linux Distribution for the NSLU2

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

#----------------------------------------------------------------------------------
# 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
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"

IMAGE_BASENAME = "${@['slugos${SITEINFO_ENDIANESS}', 'ucslugc'][bb.data.getVar('TARGET_OS', d, 1) == '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"

INHERIT += "package_ipk debian multimachine"

# 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
#----------------------------------------------------------------------------------
#

#----------------------------------------------------------------------------------
# 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!

# 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!)
