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

| SDRAM so will not boot. |

| This is the amount of CAR (Cache as RAM) reserved for use by the |

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