Thx.
I saw two FIXME on target_endian.
The whole thing about this, is to make it switchable i.e. to choose 
between LE and BE Format. For instance you can create a BE or LE jffs2 
image with mkfs.jffs2. This tool allows you switch it while flash_eraseall 
does not. So it should probably be just fine to use bb macros and keep in 
LE only.
If you want I could form a patch later.
