18 Choose a serial port for kernel debugging. NOTE: This port should
19 not be enabled under Drivers for built-in interfaces (as it has its
20 own initialization code) and should not be the same as the debug port.

86 SDRAM timing parameters. The default value is ok for

105 Configures the direction of general port A bits. 1 is out, 0 is in.
106 This is often totally different depending on the product used.
107 There are some guidelines though - if you know that only LED's are
108 connected to port PA, then they are usually connected to bits 2-4
109 and you can therefore use 1c. On other boards which don't have the
110 LED's at the general ports, these bits are used for all kinds of
111 stuff. If you don't know what to use, it is always safe to put all
112 as inputs, although floating inputs isn't good.
