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.

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.
