sh: export the sh7343 JPU to user space
PATCH 1/1 sh: export the sh7343 JPU to user space
From: Magnus Damm <[email protected]>
This patch exports the sh7343 JPU to user space using uio_pdrv_genirq, very similar to the sh7722 JPU patch by Hayama-san.
While at it fix up the end of the sh7722 JPU iomem resource.

I'll add this and the others to the queue for the next merge, after Linus pulls the current batch.
