Currently fdt_next_node() will find the next node in the blob
regardless of whether it is above, below or at the same level in the
tree as the starting node - the depth parameter is updated to indicate
which is the case.  When a depth parameter is supplied, this patch
makes it instead terminate immediately when it finds the END_NODE tag
for a node at depth 0.  In this case it returns the offset immediately
past the END_NODE tag.

This has a couple of advantages.  First, this slightly simplifies
fdt_subnode_offset(), which no longer needs to explicitly check that
fdt_next_node()'s iteration hasn't left the starting node.  Second,
this allows fdt_next_node() to be used to implement
_fdt_node_end_offset() considerably simplifying the latter function.

The other users of fdt_next_node() either don't need to iterate out of
the starting node, or don't pass a depth parameter at all.  Any
callers that really need to iterate out of the starting node, but keep
tracking depth can do so by biasing the initial depth value.

This is a semantic change, but I think it's very unlikely to break any
existing library users.

commit 04e11cf3 "rtc: add support for 4543 RTC (manufactured by e.g.
EPSON)" introduces the following build error on boards configuring e.g,
the ds1374 rtc:

ds1374.c:104: error: conflicting types for 'rtc_write'

We had a bug on 86xx in which the boot page used to bring up secondary
cores was being overwritten and used for the malloc region in u-boot.

We need to reserve the region of memory that the boot page is going to
be put at so nothing uses it.

Match determine_mp_bootpg() that was added for 86xx.  We need this to
address a bug introduced in v2009.03 with 86xx MP booting.  We have to
make sure to reserve the region of memory used for the MP bootpg() so
other u-boot code doesn't use it.

Also added a comment about how cpu_reset() is dealing w/an errata on
early 85xx MP HW.

* Use CONFIG_MP instead of CONFIG_NUM_CPUS to match 85xx
* Introduce determine_mp_bootpg() helper.  We'll need this to address a
  bug introduced in v2009.03 with 86xx MP booting.  We have to make sure
  to reserve the region of memory used for the MP bootpg() so other

* Added dummy versions of cpu_reset(), cpu_status() & cpu_release() to
  allow cmd_mp.c to build and work. In the future we should look at
  implementing all these functions. This could be common w/85xx if we
  use spin tables on 86xx.

We're missing the board_lmb_reserve definitions that allow
cpu_mp_lmb_reserve to be called; this means that Linux
is free to reallocate reserved pages.  Linux currently boots
because we're getting lucky - the page we've reserved is
high enough in memory that it isn't allocated by Linux
while we still need it to be in existence.
