[Yaffs] OOB struct for yaffs2

Hello,

I try to integrate the read yaffs2 partition function in my bootloader
(ppcboot).
I have some problem. Do you have a map contents of the 64 bytes (oob) for a nand
flash (2k per page) under yaffs2.

I have some problem to decode the structure of this information.

PS : for example in yaffs1 this struture was (in my bootloader) :

// Spare structure
typedef struct
{
    __u8  tagByte0;
    __u8  tagByte1;
    __u8  tagByte2;
    __u8  tagByte3;
    __u8  pageStatus;
    __u8  blockStatus;
    __u8  tagByte4;
    __u8  tagByte5;
    __u8  ecc1[3];
    __u8  tagByte6;
    __u8  tagByte7;
    __u8  ecc2[3];
} yaffs_Spare;

Best regards

Olivier
