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.

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.

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)

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.

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

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.

- Use consistant spacing in ppc4xx.h header (XXX + 0x01 instead

There is no point in disabling the icache on 7xx/74xx/86xx parts and not
also flushing the icache. All callers of invalidate_l1_instruction_cache()
call icache_disable() right after. Make it so icache_disable() calls
invalidate_l1_instruction_cache() for us.
Also, dcache_disable() already calls dcache_flush() so there is no point
in the explicit calls of dcache_flush().

The 'license' command includes the U-Boot license (GPLv2) into the
actual bootloader binary. The license text can be shown interactively
at the U-Boot commandline.
For products where the commandline can actually be accessed by the
end user, this helps to prevent inadvertent GPL violations, since the
GPLv2 license text can no longer be 'forgotten' to be included into
the product.
The 'license' command can be enabled by CONFIG_CMD_LICENSE.
