e2fsprogs: add populate-extfs.sh
This script is originally from Darren Hart, it will be used for creating the ext* filesystem from a given directory, which will replace the genext2fs in image_types.bbclass at the moment, we may use the mke2fs to replace this script again when it has the initial directory support. Changes of the script: * Rename it from mkdebugfs.sh to populate-extfs.sh * Add a simple usage * Add checking for the number of the parameters * Add the "regular empty file" and "fifo" file type * Set mode, uid and gid for the file * Save the command lines to a file and batch run them * Change the error message * Improve the performance * Add the support for hardlink [YOCTO #3848] Signed-off-by: Darren Hart <dvhart@linux.intel.com> Signed-off-by: Robert Yang <liezhi.yang@windriver.com> Signed-off-by: Saul Wold <sgw@linux.intel.com>
