These 48 provide various facilities for allowing a host OS to provide an 49 environment where potentially several guest OSes have only 50 limited access to the underlying hardware. This is achieved 51 without resorting to software trapping and/or instruction set 52 emulation (which would be very slow). 53 54 Intel's implementation of this is called VT-x. This option enables 55 VT-x this so that the OS that is booted by U-Boot can make use of 56 these facilities. If this option is not enabled, then the host OS 57 will be unable to support virtualisation, or it will run very 58 slowly. 59 60config FSP_ADDR 61 hex 62 default 0xfff80000 63 64config FSP_USE_UPD 65 bool 66 default n 67 68config FSP_BROKEN_HOB 69 bool 70 default y 71 72endif 73
