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.

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