# DONT FORGET TO CHANGE THE "version" VAR BELOW IF YOU MAKE CHANGES TO THIS FILE
# (C) Copyright 2001

#
# global_env
#
# file used by Hymod boards to initialise the u-boot non-volatile
# environment when u-boot is first run (it determines this by the
# absence of the environment variable "global_env_loaded")
#
# format of this file is:
#
# 1. blank lines and lines beginning with '#' are ignored
# 2. all other lines must have the form <name>=<value>
# 3. if a percent appears anywhere, it is replaced like so:
#
# %s serial number of the main board (10 digit zero filled)
# %S serial number of the main board (plain number)
# %% a percentage character
# ... otherwise the %x is discarded
#
# if first character in <name> is a dash ('-'), then an existing env var
# will not be overwritten (the dash is removed). i.e. it is only set if
# it does not exist
#
# if last character in <name> is a plus ('+'), then <value> will be appended
# to any existing env var (the plus is ignored). Duplicates of <value> are
# removed.
#
# similarly, if the last character in <name> is a minus ('-'), then any
# occurences of <value> in the current value of <name> will removed (the
# minus is ignored).
#
# leading and trailing whitespace is removed in both <name> and <value>
# (after processing any initial or final plus/minus in <name>).
#
# MISCELLANEOUS PARAMETERS
# version must always come first
version=4
# set the ip address based on the main board serial number
ipaddr=192.168.1.%S
serverip=192.168.1.254
# stop auto execute after tftp (not a very good name really)
autostart=no
# setting this to "yes" forces the global_env file to be loaded and processed
# if the current version is different to the version in the file
always_check_env=no
# BOOTING COMMANDS AND PARAMETERS
# command to run when "auto-booting"
bootcmd=bootm 40080000
# how long the "countdown" to automatically running "bootcmd" is
bootdelay=2
# how long before it "times out" console input and attempts to run "bootcmd"
bootretry=5
# arguments passed to the boot program (i.e. linux kernel) via register 6
# the linux kernel (v2.4) uses the following registers:
# r3 - address of board information structure
# r4 - address of initial ramdisk image (0 means no initrd)
# r5 - size of initial ramdisk image
# r6 - address of command line string
-bootargs=root=/dev/mtdblock5 rootfstype=squashfs ro
# these four are for hymod linux integrated into our Sun network
bootargs+=serialno=%S
bootargs+=nisclient nisdomain=mlb.dmt.csiro.au nissrvadr=138.194.112.4
bootargs+=nfsclient
bootargs+=automount
# start a web server by default
bootargs+=webserver
# give negotiation time to finish
bootargs+=netsleep=5
# then our ciscos don't pass packets for 25-30 secs after that, so
# pinging the server until it responds prevents network connections
# from failing...
bootargs+=netping
# these are old bootargs - we don't need them anymore
