/**
 * @page platforminstall Platform Build Options.
 *
 * Build options are boolean constants. The purpose of build options is to remove code
 * from the build to reduce the overall code size present in the ROM image. Unless
 * otherwise specified, the default action is to include all options. If a build option is
 * not specifically listed as disabled, then it is included into the build.
 *
 * The documented build options are imported from a user controlled file for
 * processing. The build options for all platform solutions are listed below:
 *
 * @anchor BLDOPT_REMOVE_UDIMMS_SUPPORT
 * @li @e BLDOPT_REMOVE_UDIMMS_SUPPORT @n
 *        If unbuffered DIMMs are NOT expected to be required in the system, the code that
 *        handles unbuffered DIMMs can be removed from the build.
 *
 * @anchor BLDOPT_REMOVE_RDIMMS_SUPPORT
 * @li @e  BLDOPT_REMOVE_RDIMMS_SUPPORT @n
 *         If registered DIMMs are NOT expected to be required in the system, the code
 *         that handles registered DIMMs can be removed from the build.
 *
  * @anchor BLDOPT_REMOVE_LRDIMMS_SUPPORT
 * @li @e  BLDOPT_REMOVE_LRDIMMS_SUPPORT @n
 *         If Load Reduced DIMMs are NOT expected to be required in the system, the code
 *         that handles Load Reduced DIMMs can be removed from the build.
 *
 *     @note The above three options operate independently from each other; however, at
 *     least one of the unbuffered , registered or load reduced DIMM options must be present in the build.
 *
 * @anchor BLDOPT_REMOVE_ECC_SUPPORT
 * @li @e  BLDOPT_REMOVE_ECC_SUPPORT @n
 *         Use this option to remove the code for Error Checking & Correction.
 *
 * @anchor BLDOPT_REMOVE_BANK_INTERLEAVE
 * @li @e  BLDOPT_REMOVE_BANK_INTERLEAVE @n
 *         Interleaving is a mechanism to do performance fine tuning. This option
 *         interleaves memory between banks on a DIMM.
 *
 * @anchor BLDOPT_REMOVE_DCT_INTERLEAVE
 * @li @e  BLDOPT_REMOVE_DCT_INTERLEAVE @n
 *         Interleaving is a mechanism to do performance fine tuning. This option
 *         interleaves memory from two DRAM controllers.
 *
 * @anchor BLDOPT_REMOVE_NODE_INTERLEAVE
 * @li @e  BLDOPT_REMOVE_NODE_INTERLEAVE @n
 *         Interleaving is a mechanism to do performance fine tuning. This option
 *         interleaves memory from two HyperTransport nodes.
 *
 * @anchor BLDOPT_REMOVE_PARALLEL_TRAINING
 * @li @e  BLDOPT_REMOVE_PARALLEL_TRAINING @n
 *         For multi-socket systems, training memory in parallel can reduce the time
 *         needed to boot.
 *
 * @anchor BLDOPT_REMOVE_ONLINE_SPARE_SUPPORT
 * @li @e  BLDOPT_REMOVE_ONLINE_SPARE_SUPPORT @n
 *         Online Spare support is removed by this option.
 *
 * @anchor BLDOPT_REMOVE_MULTISOCKET_SUPPORT
 * @li @e BLDOPT_REMOVE_MULTISOCKET_SUPPORT @n
 *        Many systems use only a single socket and may benefit in code space to remove
 *        this code. However, certain processors have multiple HyperTransport nodes
 *        within a single socket. For these processors, the multi-node support is
 *        required and this option has no effect.
 *
 * @anchor BLDOPT_REMOVE_ACPI_PSTATES
 * @li @e  BLDOPT_REMOVE_ACPI_PSTATES @n
 *         This option removes the code that generates the ACPI tables used in power
 *         management.
 *
 * @anchor BLDOPT_REMOVE_SRAT
 * @li @e  BLDOPT_REMOVE_SRAT @n
 *         This option removes the code that generates the SRAT tables used in performance
 *         tuning.
 *
 * @anchor BLDOPT_REMOVE_SLIT
 * @li @e  BLDOPT_REMOVE_SLIT @n
 *         This option removes the code that generates the SLIT tables used in performance
 *         tuning.
 *

 *         management.
 *
 * @anchor BLDOPT_REMOVE_DQS_TRAINING
 * @li @e  BLDOPT_REMOVE_DQS_TRAINING @n
 *         This option removes the code used in memory performance tuning.
 *
 * @anchor BLDOPT_REMOVE_EARLY_SAMPLES
 * @li @e  BLDOPT_REMOVE_EARLY_SAMPLES @n
 *         Special support for Early Samples is included. Default setting is FALSE.
 *

/**
 * @page examplecustomizations Customization Examples
 *
 * The Addendum \<plat\>Options.c file for each platform contains the minimum required
 * customizations for that platform.  That is, it contains settings which would be needed
 * to boot a SimNow! bsd for that platform.
 * However, each individual product based on that platform will have customizations necessary for
 * that hardware.  Since the actual customizations needed vary so much, they are not included in
 * the \<plat\>Options.c.  This section provides examples of useful customizations that you can use or
 * modify to suit your needs.

 *  High Speed HT frequencies are supported.  There is only one non-coherent chain.  Note the technique of
