47fde91f0c global_data: unify global flag defines
All the global flag defines are the same across all arches.  So unify them
in one place, and add a simple way for arches to extend for their needs.

50a47d0523 net: punt bd->bi_ip_addr
This field gets read in one place (by "bdinfo"), and we can replace
that with getenv("ipaddr").  After all, the bi_ip_addr field is kept
up-to-date implicitly with the value of the ipaddr env var.

70db4212fc sandbox: add getopt support
This adds simple command-line parsing to sandbox. The idea is that it
sets up the state with options provided, and this state can then be
queried later, as needed.

New flags are declared with the SB_CMDLINE_OPT_SHORT helper macro,
pointers are automatically gathered up in a special section, and
then the core code takes care of gathering them up and processing
at runtime.  This way there is no central place where we have to
store a list of flags with ifdefs.

ab4e07eb71 sandbox: allow processing before main loop
In order to pass command line arguments to sandbox we need to be able
to act on them. So take control back at the end of board_init_r() from
where we can call the main loop or do something else.

6fb6207821 sandbox: add concept of sandbox state
The state exists through the life of U-Boot. It can be adjusted by command
line options and perhaps later through a config file.  It is available to
U-Boot through state_...() calls (within sandbox code).

The primary purpose of this is to contain the "hardware" state.  It should
only be used by sandbox internal code.

8d30fcd9a1 sandbox: gpio: add basic driver for simulating GPIOs
This provides a way of simulating GPIOs by setting values which are seen
by the normal gpio_get/set_value() calls.
