2 | UEFI PI specification supersedes Inte's Framework Specification.\r | |
3 | EFI_FIRMWARE_VOLUME_PROTOCOL defined in Intel Framework Pkg is replaced by\r | |
4 | EFI_FIRMWARE_VOLUME2_PROTOCOL in MdePkg.\r | |
5 | This module produces FV on top of FV2. This module is used on platform when both of\r | |
6 | these two conditions are true:\r | |
7 | 1) Framework module consuming FV is present\r | |
8 | 2) And the platform only produces FV2\r | |
