I'm not sure if we should share the same post-image script for several boards.
It's not clear how we should maintain theses scripts in board directory.

For example for genimage (post-image.sh) :

This is the same script.
Maybe we need something board/common/post-image.sh ?

For Qemu board, maybe add the script in board/qemu/common/post-image.sh.

There is also a special case for sh4, so I'll add a second script to add
"-serial stdio -display none" instead of "-display none"

Best regards,
