Such implicit padding is IMHO a bad idea.

I think we should rather add logic similar to what we use on NOR flash
and support a "+length" syntax which indicates "please round up to the
next block boundary".

You would then write

	nand write.jffs2 addr off +${filesize}

to get the wanted behaviour.

Best regards,

Wolfgang Denk
