env: Add environment variable flags

2012-12-13T18:46:56+00:00

Currently just validates variable types as decimal, hexidecimal,
boolean, ip address, and mac address.

If the entry is not found in the env ".flags", then look in the static
one. This allows the env to override the static definitions, but prevents
the need to have every definition in the environment distracting you.

env: Use getenv_yesno() more generally

2012-12-13T18:46:55+00:00

Move the getenv_yesno() to env_common.c and change most checks for
'y' or 'n' to use this helper.

env: Refactor apply into change_ok

2012-12-13T18:46:55+00:00

Move the read of the old value to inside the check function.  In some
cases it can be avoided all together and at the least the code is only
called from one place.

Also name the function and the callback to more clearly describe what
it does.

Pass the ENTRY instead of just the name for direct access to the whole
data structure.

Pass an enum to the callback that specifies the operation being approved.

env: Refactor do_apply to a flag

2012-12-13T18:46:54+00:00

Use a flag in hsearch_r for insert mode passed from import to allow the
behavior be different based on use.

Now that "do_check" is called for all imports, ensure console init is
complete before updating the console on relocation import

env: cosmetic: Consilidate the default env definition

2012-10-19T22:25:43+00:00

There used to be a huge structure duplicated 3 times in the source.

COMMON: Use __stringify() instead of MK_STR()

2012-10-15T18:53:47+00:00

Kill multiple occurances and redeclaration of MK_STR
in favor of __stringify().

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.
