These 378ef07571SSimon Glass provide various facilities for allowing a host OS to provide an 388ef07571SSimon Glass environment where potentially several guest OSes have only 398ef07571SSimon Glass limited access to the underlying hardware. This is achieved 408ef07571SSimon Glass without resorting to software trapping and/or instruction set 418ef07571SSimon Glass emulation (which would be very slow). 428ef07571SSimon Glass 438ef07571SSimon Glass Intel's implementation of this is called VT-x. This option enables 448ef07571SSimon Glass VT-x this so that the OS that is booted by U-Boot can make use of 458ef07571SSimon Glass these facilities. If this option is not enabled, then the host OS 468ef07571SSimon Glass will be unable to support virtualisation, or it will run very 478ef07571SSimon Glass slowly. 488ef07571SSimon Glass 4943741396SBin Mengconfig FSP_ADDR 5043741396SBin Meng hex 5143741396SBin Meng default 0xfff80000 5243741396SBin Meng 5343741396SBin Mengconfig FSP_USE_UPD 5443741396SBin Meng bool 5543741396SBin Meng default n 5643741396SBin Meng 57a2e3b05eSBin Mengconfig FSP_BROKEN_HOB 58a2e3b05eSBin Meng bool 59a2e3b05eSBin Meng default y 60a2e3b05eSBin Meng 618ef07571SSimon Glassendif 62
