mflash: Initial mflash support
Mflash is fusion memory device mainly targeted consumer eletronic and
mobile phone.
Internally, it have nand flash and other hardware logics and supports
some different operation (ATA, IO, XIP) modes.
IO mode is custom mode for the host that doesn't have IDE interface.
(Many mobile targeted SoC doesn't have IDE bus)
This driver support mflash IO mode.
Followings are brief descriptions about IO mode.
1. IO mode based on ATA protocol and uses some custom command. (read

2. IO mode uses SRAM bus interface.

Noisily disable the legacy NAND subsystem.
Legacy NAND is marked for feature removal after April 2009 (i.e. this
upcoming release). There are still several boards that reference it
(though many do so only for disk-on-chip support which has been silently
disabled for a while now). These boards will now fail to build
with #error, though the code is still there if the user removes #error.
The plan is to remove the code outright in the next release, along with
any board code that refers to it (such as board/esd/common/auto_update.c).
Also, remove the legacy NAND API description from README.nand.

According to the doc/feature-removal-schedule.txt, the "autoscr"
command will be replaced by the "source" command in approximately 6
months from now.
This patch prepares this change and starts a 6 month transition
period as follows:
- The new "source" command has been added, which implements exactly
the same functionlaity as the old "autoscr" command before
- The old "autoscr" command name is kept as an alias for compatibility
- Command sequences, script files atc. have been adapted to use the
new "source" command
- Related environment variables ("autoscript", "autoscript_uname")
have *not* been adapted yet; these will be renamed resp. removed in
a separate patch when the support for the "autoscr" command get's

libfdt: Rework/cleanup fdt_next_tag()
Currently, callers of fdt_next_tag() must usually follow the call with
some sort of call to fdt_offset_ptr() to verify that the blob isn't
truncated in the middle of the tag data they're going to process.
This is a bit silly, since fdt_next_tag() generally has to call
fdt_offset_ptr() on at least some of the data following the tag for
its own operation.
This patch alters fdt_next_tag() to always use fdt_offset_ptr() to
verify the data between its starting offset and the offset it returns
in nextoffset. This simplifies fdt_get_property() which no longer has
to verify itself that the property data is all present.
At the same time, I neaten and clarify the error handling for
fdt_next_tag(). Previously, fdt_next_tag() could return -1 instead of
a tag value in some circumstances - which almost none of the callers
checked for. Also, fdt_next_tag() could return FDT_END either because
it encountered an FDT_END tag, or because it reached the end of the
structure block - no way was provided to tell between these cases.
With this patch, fdt_next_tag() always returns FDT_END with a negative
value in nextoffset for an error. This means the several places which
loop looking for FDT_END will still work correctly - they only need to
check for errors at the end. The errors which fdt_next_tag() can
report are:
- -FDT_ERR_TRUNCATED if it reached the end of the structure
block instead of finding a tag.
- -FDT_BADSTRUCTURE if a bad tag was encountered, or if the
tag data couldn't be verified with fdt_offset_ptr().
This patch also updates the callers of fdt_next_tag(), where
appropriate, to make use of the new error reporting.
Finally, the prototype for the long gone _fdt_next_tag() is removed
from libfdt_internal.h.

libfdt: Rework fdt_next_node()
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.

The mpc8313erdb board currently sets DBAT6 to cover all of the final 256MiB of

particular, flash sits at 0xfe000000-0xfe7fffff, and nothing is mapped
at the far end of the address space.
In zlib, there is a loop that references p[-1] if p is non-NULL. Under
