    5050    Driver for the on-chip serial devices (sci) will be available soon.

    52 (2) The present 'hw_init.c' file is incomplete and does not set all
    53     registers required for serial I/O. The effect is that the sci devices
    54     are 'muted' and do not successfully transmit characters to the respective
    55     I/O lines on the SH7045F.  If these ports have been properly initialized,
    56     they are not disabled by the current code. A two-part initialization will
    57     be available soon.
     52(2) The present 'hw_init.c' file provides 'early_hw_init'(void) which
     53    is normally called from 'start.S' to provide such minimal HW setup
     54    as is conveniently written in 'C' and can make use of global
     55    symbols for 7045F processor elements. It also provides
     56    'void bsp_hw_init (void)' normally called from 'bspstart.c', shortly
     57    before RTEMS itself is started.
     58
     59    These are both minimal functions intended to support the RTEMS test
     60    suites.
