40d7e99d37 bootm: refactor do_reset and os boot function args
There is no need for each OS specific function to call do_reset() we
can just do it once in bootm. This means its feasible on an error for
the OS boot function to return.

Also, remove passing in cmd_tbl_t as its not needed by the OS boot
functions.  flag isn't currently used but might be in the future so
we left it alone.

109c30fb8e Add note on dereferencing /aliases pointers
Replace the "must quote special characters" note with a hint on
how to dereference /aliases pointers by omitting the leading "/".
This feature was introduced by Kumar Gala as a libfdt enhancement

=> fdt print /aliases
aliases {
        ethernet0 = "/qe@e0100000/ucc@2000";
        ethernet1 = "/qe@e0100000/ucc@3000";
        serial0 = "/soc8360@e0000000/serial@4500";
        serial1 = "/soc8360@e0000000/serial@4600";
        pci0 = "/pci@e0008500";
};
=> fdt print ethernet0
ucc@2000 {
        device_type = "network";
        compatible = "ucc_geth";
        cell-index = <0x1>;
        reg = <0x2000 0x200>;

0219399a4e libfdt: Implement fdt_get_property_namelen() and fdt_getprop_namelen()
As well as fdt_subnode_offset(), libfdt includes an
fdt_subnode_offset_namelen() function that takes the subnode name to
look up not as a NUL-terminated string, but as a string with an
explicit length.  This can be useful when the caller has the name as
part of a longer string, such as a full path.

However, we don't have corresponding 'namelen' versions for
fdt_get_property() and fdt_getprop().  There are less obvious use
cases for these variants on property names, but there are
circumstances where they can be useful e.g. looking up property names
which need to be parsed from a longer string buffer such as user input
or a configuration file, or looking up an alias in a path with
IEEE1275 style aliases.

So, since it's very easy to implement such variants, this patch does
so.  The original NUL-terminated variants are, of course, implemented
in terms of the namelen versions.

f171746f70 libfdt: Forgot one function when cleaning the namespace
In commit b6d80a20fc293f3b995c3ce1a6744a5574192125, we renamed all
libfdt functions to be prefixed with fdt_ or _fdt_ to minimise the
chance of collisions with things from whatever package libfdt is
embedded in, pulled into the libfdt build via that environment's
libfdt_env.h.

Except... I missed one.  This patch applies the same treatment to
_stringlist_contains().  While we're at it, also make it static since
it's only used in the same file.

fc7758ee4f libfdt: Increase namespace-pollution paranoia
libfdt is supposed to easy to embed in projects all and sundry.
Often, it won't be practical to separate the embedded libfdt's
namespace from that of the surrounding project.  Which means there can
be namespace conflicts between even libfdt's internal/static functions
and functions or macros coming from the surrounding project's headers
via libfdt_env.h.

This patch, therefore, renames a bunch of libfdt internal functions
and macros and makes a few other chances to reduce the chances of
namespace collisions with embedding projects.  Specifically:
	- Internal functions (even static ones) are now named _fdt_*()

	- The type and (static) global for the error table in
          fdt_strerror() gain an fdt_ prefix

	- The unused macro PALIGN is removed

	- The memeq and streq macros are removed and open-coded in the
          users (they were only used once each)

	- Other macros gain an FDT_ prefix

	- To save some of the bulk from the previous change, an
          FDT_TAGALIGN() macro is introduced, where FDT_TAGALIGN(x) ==
          FDT_ALIGN(x, FDT_TAGSIZE)

c66830263a dtc: Enable and fix -Wcast-qual warnings
Enabling -Wcast-qual warnings in dtc shows up a number of places where
we are incorrectly discarding a const qualification.  There are also
some places where we are intentionally discarding the 'const', and we
need an ugly cast through uintptr_t to suppress the warning.  However,
most of these are pretty well isolated with the *_w() functions.  So
in the interests of maximum safety with const qualifications, this
patch enables the warnings and fixes the existing complaints.

ef4e8ce1be dtc: Enable and fix -Wpointer-arith warnings
This patch turns on the -Wpointer-arith option in the dtc Makefile,
and fixes the resulting warnings due to using (void *) in pointer
arithmetic.  While convenient, pointer arithmetic on void * is not
portable, so it's better that we avoid it, particularly in libfdt.

Also add necessary definition of uintptr_t needed by David Gibson's
changeset "dtc: Enable and fix -Wpointer-arith warnings" (the definition
comes from stdint.h, which u-boot doesn't have). -- gvb

0bb86d823b Make the YAFFS filesystem work
Recently the YAFFS filesystem support has been added to U-boot.
However, just enabling CONFIG_YAFFS2 is not enough to get it working.

ymount will generate an exception (when dereferencing mtd->readoob()), because
the genericDevice is a null pointer. Further, a lot of logging is produced
while using YAFFS fs, so logging should also be disabled.
Both issues are solved by this patch.

With this patch and CONFIG_YAFFS2 enabled, I get a readable filesystem
in U-boot, as well as in Linux.

Tested on a Atmel AT91SAM9261EK board.
