Marius Strobl ea227b498b - Add support for using LOM (Lights Out Management) and RSC (Remote System
Control) devices as console. These are microcontrollers which are either
  on-board or part of an add-on card and provide terminal server, remote
  power switch and monitoring functionality. For console usage these are
  connected to the rest of the system via a SCC or an UART. This commit adds
  support for the following variants (corresponds to what 'input-device' and
  'output-device' have to be set to):
  rsc		found on-board in E250 and supposedly some Netra, connected
		via a SAB82532, com. parameters can be determined via OFW
  rsc-console	RSC card found in E280R, Fire V4x0, Fire V8x0, connected
		via a NS16550, hardwired to 115200 8N1
  lom-console	LOMlite2 card found in Netra 20/T4, connected via a NS16550,
		hardwired to 9600 8N1

- Add my copyright to uart_cpu_sparc64.c as I've rewritten about one third
  of that file over time.

Tested on:	E250, E280R
