  29           Select this option to add a System Agent binary to
  30           the resulting U-Boot image. MRC stands for Memory Reference Code.
  31           It is a binary blob which U-Boot uses to set up SDRAM.
  32
  33           Note: Without this binary U-Boot will not be able to set up its
  34           SDRAM so will not boot.

  40           This is the amount of CAR (Cache as RAM) reserved for use by the
  41           memory reference code. This should be set to 16KB (0x4000 hex)
  42           so that MRC has enough space to run.

  58           Virtual Machine Extensions are provided in many x86 CPUs. These
  59           provide various facilities for allowing a host OS to provide an
  60           environment where potentially several guest OSes have only
  61           limited access to the underlying hardware. This is achieved
  62           without resorting to software trapping and/or instruction set
  63           emulation (which would be very slow).
  64
  65           Intel's implementation of this is called VT-x. This option enables
  66           VT-x this so that the OS that is booted by U-Boot can make use of
  67           these facilities. If this option is not enabled, then the host OS
  68           will be unable to support virtualisation, or it will run very
  69           slowly.
