    [PATCH] m32r: SIO driver · 0b43f270
    Hirokazu Takata authored
    Here is a patch to support the M32R SIO (serial IO) driver.
    
    This driver supports the M32R serial ports.
    - Supports two types M32R serial interfaces; M32R_SIO and M32R_PLDSIO.
    - With SMP safeness.
    
    Currently the M32R_PLDSIO serial interface, which is implemented on a PLD
    on the M3T-M32700UT evaluation board, has slightly different specification
    from the integrated peripheral SIO (M32R_SIO).  Now we can select them by
    CONFIG_ option.
    
    It is a serial-core based driver, based on drivers/serial/8250.c.  Any
    comments or suggestions will be appreciated.
