| 18 | # Currently, it is required that the BIOS region be a multiple of 8KiB. |
| 19 | # This is required so that the recovery mechanism can find SIGN_CSE |
| 20 | # region aligned to 4K at the center of BIOS region. Since the |
| 21 | # descriptor at the beginning uses 4K and BIOS starts at an offset of |
| 22 | # 4K, a hole of 4K is created towards the end of the flash to compensate |
| 23 | # for the size requirement of BIOS region. |
| 24 | # FIT tool thus creates descriptor with following regions: |
| 25 | # Descriptor --> 0 to 4K |
| 26 | # BIOS --> 4K to 0xf7f000 |
| 27 | # Device ext --> 0xf7f000 to 0xfff000 |
