- * Problems with CONFIG_SYS_64BIT_LBA:
- *
- * struct disk_partition.start in include/part.h is sized as ulong.
- * When CONFIG_SYS_64BIT_LBA is activated, lbaint_t changes from ulong to uint64_t.
- * For now, it is cast back to ulong at assignment.
- *
- * This limits the maximum size of addressable storage to < 2 Terra Bytes
+ * NOTE:
+ * when CONFIG_SYS_64BIT_LBA is not defined, lbaint_t is 32 bits; this
+ * limits the maximum size of addressable storage to < 2 Terra Bytes
