Subject: [PATCH 08/30] mamba mvebu: add jffs2 image target for Mamba
The firmware image of Mamba board is generated by concatenating the
kernel image uImage with the jffs2 root file system (block size 128KB).
If the kernel file is less than 3MB, the uImage is padded to 3MB before
the concatenation applied, this makes the image complied with the
partition layout of Mamba board
