Tom Rini 448e2b6327 event: Correct dependencies on the EVENT framework
The event framework is just that, a framework. Enabling it by itself
does nothing, so we shouldn't ask the user about it. Reword (and correct
typos) around this the option and help text. This also applies to
DM_EVENT and EVENT_DYNAMIC. Only EVENT_DEBUG and CMD_EVENT should be
visible to the user to select, when EVENT is selected.

With this, it's time to address the larger problems. When functionality
uses events, typically via EVENT_SPY, the appropriate framework then
must be select'd and NOT imply'd. As the functionality will cease to
work (and so, platforms will fail to boot) this is non-optional and
where select is appropriate. Audit the current users of EVENT_SPY to
have a more fine-grained approach to select'ing the framework where
used. Also ensure the current users of event_register and also select
EVENT_DYNAMIC.

help
Virtual Machine Extensions are provided in many x86 CPUs. These
provide various facilities for allowing a host OS to provide an
environment where potentially several guest OSes have only
limited access to the underlying hardware. This is achieved
without resorting to software trapping and/or instruction set
emulation (which would be very slow).
Intel's implementation of this is called VT-x. This option enables
VT-x this so that the OS that is booted by U-Boot can make use of
these facilities. If this option is not enabled, then the host OS
will be unable to support virtualisation, or it will run very
slowly.
