PS3, Line 97: /* Since coreboot is usually compiled 32bit, gcc will align 64bit
            :  * types to 32bit boundaries. If the coreboot table is dumped on a
            :  * 64bit system, a uint64_t would be aligned to 64bit boundaries,
            :  * breaking the table format.
            :  *
            :  * lb_uint64 will keep 64bit coreboot table values aligned to 32bit
            :  * to ensure compatibility. They can be accessed with the two functions
            :  * below: unpack_lb64() and pack_lb64()
> It's still nice to have this comment, with some modification.
