Constant ENTRY_POINT_SIZE 

pub const ENTRY_POINT_SIZE: usize = _; // 24usize

Size in bytes of the SMBIOS 3.0 (64-bit) entry point (_SM3_). Callers that place the entry point and structure table separately (e.g. the aarch64 EFI configuration-table path) use this to reserve space for the entry point before knowing the structure table’s address.
