# 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
