#@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-???.conf instead:
# Explanation of the naming
#
# nslu2-dist - the base distro configuration for an NSLU2
# nslu2-[bl][at][gu] - a specific configuration encoded as follows:
#
# b or l - big or little endian
# set ARCH_BYTE_SEX to match
#
# 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
#
# The following names are deprecated:
#
# openslug - the historical name of a canonical nslu2-bag distro,
# used generically for NSLU2 specific distro features and
# the default OVERRIDE for all these NSLU2 builds
# ucslugc - the historical (and obsolete) name of nslu2-btu
# also the name of a standard nslu2-btu distro with a package feed
#
#----------------------------------------------------------------------------------
# STANDARD SLUGOS DEFINITIONS
#----------------------------------------------------------------------------------
# The following must be set in the top level distro file:
#
#DISTRO_NAME
#DISTRO_VERSION
#DISTRO_FEED
#DISTRO_TYPE
# The following must also be set, they define the basic format of the build
#
#ARCH_BYTE_SEX "be" or "le"
#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-${ARCH_BYTE_SEX}-${ARM_INSTRUCTION_SET}-${TARGET_OS}"
DISTRO_VERSION ?= "INVALID"
DISTRO_FEED ?= "INVALID"
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"
# The value of DISTRO_BASE is set to 'openslug' to pick up the original openslug
# overrides, slugos is the preferred override!
#FIXME: remove openslug
DISTRO_BASE = ":slugos:openslug"
# pull in the frozen list of bbfiles - this sets BBFILES and this will override any
# setting in local.conf Since this depends on ${DISTRO} it doesn't actually do
# anything by default unless conf/distro/${DISTRO}-packages.conf exists.
include conf/distro/freeze.conf
#----------------------------------------------------------------------------------
# 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
# -------------------
#FIXME: this is historical, there should be a minimal slugos device table and
# this stuff shouldn't be in here at all (put it in slugos-image.bb!)
# Why have anything in the config file to control the image build - why not
# just select a different image .bb file (e.g. slugos-ramdisk-image.bb) to
# build with different options.
IMAGE_FSTYPES = "jffs2"
IMAGE_SEX = "${@['big-endian', 'little-endian'][bb.data.getVar('ARCH_BYTE_SEX', d, 1) == 'le']}"
OPENSLUG_DEVICE_TABLE = "${@bb.which(bb.data.getVar('BBPATH', d, 1), 'files/device_table-openslug.txt')}"
EXTRA_IMAGECMD_jffs2 = "--pad --${IMAGE_SEX} --eraseblock=0x20000 -D ${OPENSLUG_DEVICE_TABLE}"
# 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"
# IMAGE_PREPROCESS_COMMAND is run before making the image. In SlugOS the
# kernel image is removed from the root file system to recover the space used -
# SlugOS is assumed to boot from a separate kernel image in flash (not in the
# root file system), if this is not the case the following must not be done!
IMAGE_PREPROCESS_COMMAND = "rm ${IMAGE_ROOTFS}/boot/zImage*;"
# Building a full image. If you add the following extra commands will be
# appended to the openslug-image build by classes/nslu2-jffs2-image.bbclass
# (note that you can, instead, simply add 'inherit nslu2-jffs2-image' to
# openslug-image.bb). If you do this you will need to find a source for the
# LinkSys software to be placed in the full image - 'RedBoot' (the boot loader),
# 'Trailer' (just a bunch of bytes to flag the image as valid) and 'SysConf'
# (actually just a block of unset data - you could modify this to pre-configure
# the SysConf partition of the image). If you own an NSLU2 then this data is
# already in the flash of the NSLU2 and you can download it (including new
# versions) from the LinkSys web site - the bbclass will output information
# about where to put the downloaded data.
#
#NOTE: you do not actually need the boot loader in normal use because it is
# *not* overwritten by a standard upslug upgrade, so you can make an image with
# just non-LinkSys software which can be flashed into the NSLU2.
#FIXME: this should not be here, only slugos-image.bb needs this
#INHERIT += "nslu2-jffs2-image"
# EXTRA PACKAGES
# --------------
# SlugOS builds an image with no extra packages - to add packages to the
# firmware copy this file (to make a new 'distro' configuration file) and change
# 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!
SLUGOS_EXTRA_RDEPENDS ?= ""
SLUGOS_EXTRA_DEPENDS ?= ""
# These depends define native utilities - they do not get put in the flash.
# upslug2 (in tmp/work/upslug2-native-*) is the program to write the NSLU2 flash
# Override this as desired - it makes no difference to the final image.
SLUGOS_NATIVE_DEPENDS ?= "upslug2-native"
