2015-03-28Patch to mkenvimage to handle text files with length that exceed env sizeBrian McFarland
The current head revision of mkenvimage (e72be8947e129f5ab274c0a9f235d2cc0014b2ea) 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. >From 39ff30190c2bf687861f4b4b33230f1944fb64f9 Mon Sep 17 00:00:00 2001 From: Brian McFarland <bmcfarland@rldrake.com> Date: Thu, 12 Mar 2015 11:37:19 -0400 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.
2014-11-10Added support for comments in input to mkenvimage.Dominik Muth
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. Signed-off-by: Dominik Muth <dominik.muth@bkvibro.com>
2013-08-16tools/Makefile: Move _GNU_SOURCE to MakefileYork Sun
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. Signed-off-by: York Sun <yorksun@freescale.com> Acked-by: Simon Glass <sjg@chromium.org>

2012-07-02tools/mkenvimage.c: fix basename(3) usageAndreas Bießmann
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): ---8<--- mkenvimage.c: In function ‘main’: mkenvimage.c:105: warning: implicit declaration of function ‘basename’ mkenvimage.c:105: warning: assignment makes pointer from integer without a cast --->8--- Signed-off-by: Andreas Bießmann <andreas.devel@googlemail.com> cc: Keith Mok <ek9852@gmail.com>
