| 78 | * #undef CONFIG_SYS_64BIT_LBA |

| 80 | * typedef u_int64_t lbasize_t; |

| 85 | * But we cannot just undefine CONFIG_SYS_64BIT_LBA, because then in |
| 86 | * api/api_storage.c the type signature of lbaint_t will be different if |
| 87 | * CONFIG_SYS_64BIT_LBA is enabled for the board, which can result in various |
| 88 | * bugs. |
| 89 | * So simply define lbasize_t as an unsigned long, since this was what was done |
| 90 | * anyway for at least 13 years, but don't undefine CONFIG_SYS_64BIT_LBA. |
