enhancements to MPC8260 serial driver ...

- configure any, or all, SMC and SCC ports to be serial ports; the only
  wiring setup that allows this is for SCC[1-4]<=>BRG[1-4] and SMC[1-2]
  <=>BRG[7-8]
- support serial console and/or kgdb port on any, or none, SMC or SCC port
- permanent mapping of S[MC]Cn<=>ttySn i.e. ttyS0 is always SMC1, ttyS1 is
  always SMC2, ttyS2 is always SCC1, and so on.
- most i/o pin configurations covered by simple config options i.e. SCC2
  and SCC3 have "primary" or "secondary" i/o pin configurations
- supports using an external clock source for any BRG, instead of BRGCLK

Cheers!

Can you split this up into 5 logical patches?  Thanks.
