env: fix crash using default -f -a

2012-10-05T18:07:42+00:00

env default -a -f calls env_check_apply on all existing environment
variables with a NULL value for "newval" as a way of cleaning up.
This causes string manipulation functions to crash on most architectures.
So replace a NULL argument with an empty string.

OMAP: networking support for SPL

2012-10-01T17:02:14+00:00

This patch adds support for networking in SPL. Some devices are
capable of loading SPL via network so it makes sense to load the
main U-Boot binary via network too. This patch tries to use
existing network code as much as possible. Unfortunately, it depends
on environment which in turn depends on other code so SPL size
is increased significantly. No effort was done to decouple network
code and environment so far.

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.

env: unify logic to check and apply changes

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

The logic of checking special parameters (e.g. baudrate, stdin, stdout,
for a valid value and/or whether can be overwritten) and applying the
new value to the running system is now all within a single function
env_check_apply() which can be called whenever changes are made
to the environment, no matter if by set, default or import.

With this patch env_check_apply() is only called by "env set",
retaining previous behavior.

env: cosmetic: drop assignment i = iomux_doenv()

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

iomux_doenv() can only return 0 or 1.
So there is no need to save its return value in variable i, as checking
its truth value within an if statement is enough.
