The current head revision of mkenvimage
(e72be8947e) will prevent you from creating
an env image from a text file that is larger than the env length specified
by the '-s' option. That doesn't make sense given that the tool now allows
comments and blank lines. This patch removes that limitation and allows
longer text files to be used.
I don't have time / desire at the moment to figure out "patman" and could
really care less if this is adopted up stream. Just figured I would share
in case anybody else finds it useful enough to take time to do a proper
patch.

Subject: [PATCH] In mkenvimage, removed the check that prevented using a
source text file larger than the output environment image. Instead, the main
parsing loop checks to see if the environment buffer is full, and quits if it
is. After the main parse loop, a second loop swallows comments and
whitespace until either the EOF is reached or more env vars are found, in
which case an error will be thrown.
This patch adds support for comments in the input to mkenvimage, i.e. in
the environment source: All lines starting with a # in the firs column
will be ignored.
Additionally empty lines will also be ignored.

Commit 669dfc2e adds libfdt_env.h to HOSTCPPFLAGS. It causes stdio.h
to be included before _GNU_SOURCE is defined in C files. On some old hosts
some prototypes are protected by #ifdef __USE_GNU, which is set when
_GNU_SOURCE is defined.

Use the POSIX variant of basename due to BSD systems (e.g. OS X) do not provide
GNU version of basename(3). It is save to use the POSIX variant here cause we do
never use argv[0] later on which may be modified by the basename(3) POSIX
variant.
On systems providing GNU variant the GNU variant should be used since string.h
is included before libgen.h. Therefore let the _GNU_SOURCE as is.
This patch fixes following warning (on OS X):

mkenvimage.c: In function ‘main’:

Since the original implementation indicates explicit error handling
we turn off getopt()'s internal error messaging to avoid duplicate
error messages. Additionally we add ':' (missing option argument)
error handling.
