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 | # | |
e2211743 WD |
31 | # 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 | |
6dd652fa | 40 | # ... otherwise the %x is discarded |
e2211743 WD |
41 | # |
42 | # if first character in <name> is a dash ('-'), then an existing env var | |
6dd652fa WD |
43 | # will not be overwritten (the dash is removed). i.e. it is only set if |
44 | # it does not exist | |
e2211743 WD |
45 | # |
46 | # if last character in <name> is a plus ('+'), then <value> will be appended | |
6dd652fa | 47 | # to any existing env var (the plus is ignored). Duplicates of <value> are |
e2211743 WD |
48 | # removed. |
49 | # | |
6dd652fa WD |
50 | # 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>). | |
56 | # | |
