# YAFFS
# The layout itself is undocumented, determined by the memory layout of the 
# reference implementation. This signature is derived from the
# reference implementation code and generated test cases
# We recognize the start of an object header defined by yaffs_obj_hdr:
# (Note the values being encoded depending on platform endianess)

# u32 type  /* enum yaffs_obj_type, valid 1-5  */
# u32 parent_obj_id; /* 1 for root objects we recognize */
# u16 sum_no_longer_used; /* checksum of name. Not used by YAFFS and memset to 0xFF */
# YCHAR name[YAFFS_MAX_NAME_LENGTH + 1];

# mkyaffsimage always writes a root directory with empty name, then processing the target directory contents
# mkyaffs2image directly proceeds to writing entries with the appropriate u32 YAFFS_OBJECT_TYPE (1-5 valid), each with parent id 1
