At present we support multiple environment drivers but there is not way to select between them at run time. Also settings related to the position and size of the environment area are global (i.e. apply to all locations). Until these limitations are removed we cannot really support more than one environment location. Adjust the location to be a choice so that only one can be selected. By default the environment is 'nowhere', meaning that the environment exists only in memory and cannot be saved. Also expand the help for the 'nowhere' option and move it to the top since it is the default.

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.
