+# 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
# %s serial number of the main board (10 digit zero filled)
# %S serial number of the main board (plain number)
# %% a percentage character
-#
-# no whitespace is removed in either <name> or <value>
+# ... 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).
+# 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 removed). Duplicates of <value> are
+# 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
+# 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
