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.
Note: Without this binary U-Boot will not be able to set up its
SDRAM so will not boot.

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

so that MRC has enough space to run.

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.
