These 50 provide various facilities for allowing a host OS to provide an 51 environment where potentially several guest OSes have only 52 limited access to the underlying hardware. This is achieved 53 without resorting to software trapping and/or instruction set 54 emulation (which would be very slow). 55 56 Intel's implementation of this is called VT-x. This option enables 57 VT-x this so that the OS that is booted by U-Boot can make use of 58 these facilities. If this option is not enabled, then the host OS 59 will be unable to support virtualisation, or it will run very 60 slowly. 61 62 config FSP_ADDR 63 hex 64 default 0xfff80000 65 66 config FSP_USE_UPD 67 bool 68 default n 69 70 config FSP_BROKEN_HOB 71 bool 72 default y 73 74 endif 75
