env: make "env default" selective, check and apply

2012-09-18T19:01:52+00:00

Change the syntax (user API) for "env default":
  -f: override write-once variables
  var... : accept individual variable(s)
  -a: all (resetting the whole env is NOT the default behavior)

Enable variable checking and make changes effective by
enabling do_apply argument to himport_r().

env: add check/apply logic to himport_r()

2012-09-18T19:01:52+00:00

Change hashtable so that a callback function will decide whether a
variable can be overwritten, and possibly apply the changes.

So add a new field to struct hsearch_data:

 o "apply" callback function to check whether a variable can be
    overwritten, and possibly immediately apply the changes;
    when NULL, no check is performed.

And a new argument to himport_r():
 o "do_apply": whether to call the apply callback function

NOTE: This patch does not change the current behavior.

env: make himport_r() selective on variables

2012-09-18T19:01:52+00:00

Add 2 new arguments to himport_r():

 o "nvars", "vars": number and list of variables to take into account
   (0 means ALL)

NOTE: This patch does not change the current behaviour.

Add env vars describing U-Boot target board

2012-07-09T20:44:33+00:00

This can be useful for generic scripts. For example, rather than hard-
coding a script to ext2load tegra-harmony.dtb, it could load
${soc}-${board}.dtb and hence not need adjustments to run on multiple
boards.

bootstage: Replace show_boot_progress/error() with bootstage_...()

2012-03-18T20:41:39+00:00

These calls should not be made directly any more, since bootstage
will call the show_boot_...() functions as needed.

bootstage: Convert net progress numbers to enums

2012-03-18T20:33:05+00:00

This changes over the network-related progress numbers to use enums
from bootstage.h.

bootstage: Use show_boot_error() for -ve progress numbers

2012-03-18T19:56:00+00:00

Rather than the caller negating our progress numbers to indicate an
error has occurred, which seems hacky, add a function to indicate this.

env: factor out the env_get_char_spec() function

2012-01-05T15:34:10+00:00

env_get_char_spec() function is duplicated across multiple environment
files.
Remove the duplication by providing a default implementation.
Add "weak" declaration, so the default implementation can be overridden.
