101Port Description
102Console driver
103---------------
104
105This BSP contains a console driver for polled and interrupt-driven
106operation. It supports SCCs and SMCs.
107During BSP configuration, various variables can be set to activate a
108certain channels and to specify the console channel:
109
110CONS_SMC1_MODE, CONS_SMC2_MODE, CONS_SCC[1-4]_MODE can be set to
111CONS_MODE_UNUSED, CONS_MODE_POLLED or CONS_MODE_IRQ
112
113The driver always uses termios.

119Floating-point
120--------------
121
122The MPC8xx do not have floating-point units. All code should
123get compiled with the appropriate -mcpu flag. The nof variants of the gcc
124runtime libraries should be used for linking.

126
127
128Miscellaneous
129-------------
130
131All development was based on the mbx8xx and gen68360 port.
