sh: sh4a scif pdata (sh7343/sh7366/sh7722/sh7723/sh7724)
Browse files Browse the repository at this point in the history 
This patch breaks out the sh4a scif serial port platform
data from a shared platform device to one platform
device per port. Also, add serial ports to the list of
early platform devices.

Only sh4a SuperH Mobile processors are modified by this
patch.
