These 51 provide various facilities for allowing a host OS to provide an 52 environment where potentially several guest OSes have only 53 limited access to the underlying hardware. This is achieved 54 without resorting to software trapping and/or instruction set 55 emulation (which would be very slow). 56 57 Intel's implementation of this is called VT-x. This option enables 58 VT-x this so that the OS that is booted by U-Boot can make use of 59 these facilities. If this option is not enabled, then the host OS 60 will be unable to support virtualisation, or it will run very 61 slowly. 62 63config FSP_ADDR 64 hex 65 default 0xfff80000 66 67config FSP_USE_UPD 68 bool 69 default n 70 71config FSP_BROKEN_HOB 72 bool 73 default y 74 75endif 76
