| 7 | StandAlomeMM is a PE/COFF binary produced by EDK2. For Arm platforms we |
| 8 | can compile and use it, in combination with OP-TEE to store EFI variables |
| 9 | in and RPMB partition of our eMMC. |

| 45 | U-Boot Build instructions |
| 46 | ************************* |
| 47 | |
| 48 | Although the StandAloneMM binary comes from EDK2, using and storing the |
| 49 | variables is currently available in U-Boot only. |

| 59 | |
| 60 | Enable ``CONFIG_OPTEE``, ``CONFIG_CMD_OPTEE_RPMB`` and ``CONFIG_EFI_MM_COMM_TEE`` |

| 67 | .. warning:: |
| 68 | |
| 69 | - Your OP-TEE platform port must support Dynamic shared memory, since that's |
| 70 | the only kind of memory U-Boot supports for now. |
