| /** |
| * @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. |
| * |
| * @note The above two options operate independently from each other; however, at |
| * least one of the unbuffered or registered 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_MSG_BASED_C1E |
| * @li @e BLDOPT_REMOVE_MSG_BASED_C1E @n |

| * 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. |
