Thanks for this new version. For new version, it is customary to change
the title of the patch this way:

	[PATCH v2] ....

To do this, use:

	git format-patch --subject-prefix="PATCH v2"

> ---

Also, we generally try to put a changelog here, that describes what
changed since v1. See also
http://buildroot.org/downloads/manual/manual.html#submitting-patches.

Finally, the title of your commit should ideally be:

	nwipe: new package

that's kind of our convention for new packages, and generally our
commit titles are always:

	<package>: <description>

All patches should have a description + Signed-off-by. See
http://buildroot.org/downloads/manual/manual.html#_format_and_licensing_of_the_package_patches.

Using $(...) instead of ${...} is more common in Makefiles.

Please also add a description + Signed-off-by here.

Did you get the change to submit those patches to the upstream nwipe
project?

When you select a package, you need to replicate the dependencies of
this package into your package (yes it's silly, but that's how the
kconfig stuff works). So since parted depends on wchar support, you
need to:

	depends on BR2_USE_WCHAR # parted

And here add:

comment "nwipe needs a toolchain w/ wchar"
	depends on BR2_USE_MMU
	depends on !BR2_USE_WCHAR

This looks good.
