4194b3668a Add support to disable cpu's in multicore processors
Add a disable sub-command to the cpu command that allows for disabling
cores in multicore processors.  This can be useful for systems that are
using multicore chips but aren't utilizing all the cores as a way to
reduce power and possibly improve performance.

Also updated an added missing copyright.

0e870980a6 8xxx: Removed CONFIG_NUM_CPUS from 85xx/86xx
The number of CPUs are getting detected dynamically by checking the
processor SVR value.  Also removed CONFIG_NUM_CPUS references from all
the platforms with 85xx/86xx processors.

This can help to use the same u-boot image across the platforms.

Also revamped and corrected few Freescale Copyright messages.

a89c33db96 General help message cleanup
Many of the help messages were not really helpful; for example, many
commands that take no arguments would not print a correct synopsis
line, but "No additional help available." which is not exactly wrong,
but not helpful either.

Commit ``Make "usage" messages more helpful.'' changed this
partially. But it also became clear that lots of "Usage" and "Help"
messages (fields "usage" and "help" in struct cmd_tbl_s respective)
were actually redundant.

This patch cleans this up - for example:

Before:
	=> help dtt
	dtt - Digital Thermometer and Thermostat

	Usage:
	dtt         - Read temperature from digital thermometer and thermostat.

After:
	=> help dtt
	dtt - Read temperature from Digital Thermometer and Thermostat

	Usage:
	dtt

2fb2604d5c Command usage cleanup
Remove command name from all command "usage" fields and update
common/command.c to display "name - usage" instead of
just "usage". Also remove newlines from command usage fields.

The following changes are needed to be inline with ePAPR v0.81:

* r4, r5 and now always set to 0 on boot release
* r7 is used to pass the size of the initial map area (IMA)
* EPAPR_MAGIC value changed for book-e processors
* changes in the spin table layout
* spin table supports a 64-bit physical release address

ec2b74ffd3 85xx: Added support for multicore boot mechanism
Added the cpu command that provides a generic mechanism to get status,
reset, and release secondary cores in multicore processors.

Added support for using the ePAPR defined spin-table mechanism on 85xx.
