Remove All CVS Id Strings Possible Using a Script

Script does what is expected and tries to do it as
smartly as possible.

+ remove occurrences of two blank comment lines

next to each other after Id string line removed.

+ remove entire comment blocks which only exited to

contain CVS Ids

+ If the processing left a blank line at the top of

a file, it was removed.

98Console driver
99---------------
100
101This BSP contains a console driver for polled and interrupt-driven
102operation. It supports SCCs and SMCs.
103During BSP configuration, various variables can be set to activate a
104certain channels and to specify the console channel:
105
106CONS_SMC1_MODE, CONS_SMC2_MODE, CONS_SCC[1-4]_MODE can be set to
107CONS_MODE_UNUSED, CONS_MODE_POLLED or CONS_MODE_IRQ
108
109The driver always uses termios.

115Floating-point
116--------------
117
118The MPC8xx do not have floating-point units. All code should
119get compiled with the appropriate -mcpu flag. The nof variants of the gcc
120runtime libraries should be used for linking.

124Miscellaneous
125-------------
126
127All development was based on the mbx8xx and gen68360 port.
