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. config FSP_ADDR hex default 0xfff80000 config FSP_USE_UPD bool default n config FSP_BROKEN_HOB bool default y endif
