| - 在这种方式中 NEMU 在生成 Checkpoint 时，通常需要添加一段恢复程序 `gcpt.bin` ，在 `(0x80100000, 100000)`。因此在生成 workload 时，需要避开这一段空间，将起始地址设置在 `0x80100000` 。 | ||
| - 如果你使用的是 OpenSBI，那么不必考虑设置 OpenSBI 的起始地址，仅需考虑 OpenSBI 的负载（例如 Linux Kernel 就是一种 OpenSBI 的负载）的起始地址，你需要在 OpenSBI 构建时设置 `FW_PAYLOAD_OFFSET=0x100000` 或任意加上 0x80100000 后能够按照 2M 对齐的地址（例如 0x80100000 + 0x10000 或 0x80100000 + 0x300000）。 | ||
| - 此外，为了避免 Linux Kernel 意外的使用了我们给 `gcpt.bin` 预留的空间，我们需要给 OpenSBI 使用的设备树中使用的 `memory` 指定一段预留空间，这段空间的大小取决于你给 `gcpt.bin` 预留的空间的大小，也就是上述 `FW_PAYLOAD_OFFSET` 设置的值。 |

“指定一段预留空间” 的具体操作应该给一个链接？不知道这里的上下文是否有提供？
