0099 Console driver
0100 ---------------
0101 This BSP contains a console driver for polled and interrupt-driven
0102 operation. It supports SCCs and SMCs.
0103 During BSP configuration, various variables can be set to activate a
0104 certain channels and to specify the console channel:
0105
0106 CONS_SMC1_MODE, CONS_SMC2_MODE, CONS_SCC[1-4]_MODE can be set to
0107 CONS_MODE_UNUSED, CONS_MODE_POLLED or CONS_MODE_IRQ
0108
0109 The driver always uses termios.
0110
0111
0112 Floating-point
0113 --------------
0114 The MPC8xx do not have floating-point units. All code should
0115 get compiled with the appropriate -mcpu flag. The nof variants of the gcc
0116 runtime libraries should be used for linking.
0117
0118
0119
0120 Miscellaneous
0121 -------------
0122 All development was based on the mbx8xx and gen68360 port.
