Subject: Patch from gtj: http://bugs.uclibc.org/view.php?id=40
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=dda90723ce4a6d8c84dbf7c66ef8b2c4e5d67b2c;p=buildroot.git

Patch from gtj: bugs.uclibc.org/view.php?id=40

0000040: Adds options to jffs2 filesystem creation

Brings jffs2 up to the 20041007 build level so it will compile with both 2.4
and 2.6 kernels.

Adds ability to specify eraseblock and pad sizes, permissions squash,
big/little endian and device table in the configuration.

Also adds capability to copy the resulting image to a secondary location like
a tftp server's root directory.

mtd.patch adds capabilities of the previously attached patch plus allows you to
compile a version of the utilities to run on the target system.

So now there's a set of config options under package to compile the utils for
distribution to the target and a set of config options under target to create a
jffs2 filesystem.
