68 Select this option to add a System Agent binary to
69 the resulting U-Boot image. MRC stands for Memory Reference Code.
70 It is a binary blob which U-Boot uses to set up SDRAM.

113 help
114 Virtual Machine Extensions are provided in many x86 CPUs. These
115 provide various facilities for allowing a host OS to provide an
116 environment where potentially several guest OSes have only
117 limited access to the underlying hardware. This is achieved
118 without resorting to software trapping and/or instruction set
119 emulation (which would be very slow).
120
121 Intel's implementation of this is called VT-x. This option enables
122 VT-x this so that the OS that is booted by U-Boot can make use of
123 these facilities. If this option is not enabled, then the host OS
124 will be unable to support virtualisation, or it will run very
125 slowly.
