25# global_env
26#
27# file used by Hymod boards to initialise the u-boot non-volatile
28# environment when u-boot is first run (it determines this by the
29# absence of the environment variable "global_env_loaded")
30#
wdenke2211742002-11-02 23:30:20 +000031# format of this file is:
32#
33# 1. blank lines and lines beginning with '#' are ignored
34# 2. all other lines must have the form <name>=<value>
35# 3. if a percent appears anywhere, it is replaced like so:
36#
37# %s serial number of the main board (10 digit zero filled)
38# %S serial number of the main board (plain number)
39# %% a percentage character
wdenk6dd652f2003-06-19 23:40:20 +000040# ... otherwise the %x is discarded
wdenke2211742002-11-02 23:30:20 +000041#
42# if first character in <name> is a dash ('-'), then an existing env var
wdenk6dd652f2003-06-19 23:40:20 +000043# will not be overwritten (the dash is removed). i.e. it is only set if
44# it does not exist
wdenke2211742002-11-02 23:30:20 +000045#
46# if last character in <name> is a plus ('+'), then <value> will be appended
wdenk6dd652f2003-06-19 23:40:20 +000047# to any existing env var (the plus is ignored). Duplicates of <value> are
wdenke2211742002-11-02 23:30:20 +000048# removed.
49#
wdenk6dd652f2003-06-19 23:40:20 +000050# similarly, if the last character in <name> is a minus ('-'), then any
51# occurences of <value> in the current value of <name> will removed (the
52# minus is ignored).
53#
54# leading and trailing whitespace is removed in both <name> and <value>
55# (after processing any initial or final plus/minus in <name>).
