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.

|
|
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.
