EM85XX读NTFS修正代码包

/*
 * ntfstypes.h - This file defines four things:
 * - Generic platform independent fixed-size types (e.g. ntfs_u32).
 * - Specific fixed-size types (e.g. ntfs_offset_t).
 * - Macros that read and write those types from and to byte arrays.
 * - Types derived from OS specific ones.
