here it is:

struct imx_flash_header_v2 __flash_header_section flash_header =
{
    .header.tag         = IVT_HEADER_TAG,
    .header.length      = cpu_to_be16(32),
    .header.version     = IVT_VERSION,

    .entry              = APP_DEST + 0x1000,
    .dcd_ptr            = APP_DEST + 0x400 + offsetof(struct 
imx_flash_header_v2, dcd),
    .boot_data_ptr      = APP_DEST + 0x400 + offsetof(struct 
imx_flash_header_v2, boot_data),
    .self               = APP_DEST + 0x400,

    .boot_data.start    = APP_DEST,
    .boot_data.size     = 0x40000,

    .dcd.header.tag     = DCD_HEADER_TAG,
    .dcd.header.length  = cpu_to_be16(sizeof(struct imx_dcd) + 
sizeof(dcd_entry)),
    .dcd.header.version = DCD_VERSION,

    .dcd.command.tag    = DCD_COMMAND_WRITE_TAG,
    .dcd.command.length = cpu_to_be16(sizeof(struct imx_dcd_command) + 
sizeof(dcd_entry)),
    .dcd.command.param  = DCD_COMMAND_WRITE_PARAM,
};


there is another struct:

struct imx_fcb_header __flash_header_fcb fcb_entry =
{
    .fcb_marker = 0x20424346,
    .fcb_version = 0x01,
    .st_pg_prm = 0x0,
    .st_pg_sec = 0x0,
    .reserved3[0] = 0x6b,
    .reserved3[1] = 0x6b,
    .st_pg_dbbt = 0x0,
    .bbm_off_main = 0x0,
    .bi_swap = 0x0,
    .bbm_off_spare = 0x0,
};

On i.MX53 there might be a similar issue. You probably have something
like this in your board:

struct imx_flash_header_v2 __flash_header_section flash_header = {
                 .header.tag                             = IVT_HEADER_TAG,
                 .header.length                          = 
cpu_to_be16(32),
                 .header.version                                 = 
IVT_VERSION,

                 .entry                                          = 
APP_DEST + 0x1000,
                 .dcd_ptr                                = APP_DEST + 
0x400 + offsetof(struct imx_flash_header_v2, dcd),
                 .boot_data_ptr                          = APP_DEST + 
0x400 + offsetof(struct imx_flash_header_v2, boot_data),
                 .self                                           = 
APP_DEST + 0x400,

                 .boot_data.start                = APP_DEST,
                 .boot_data.size                                 = 
DCD_BAREBOX_SIZE,

.boot_data.size is the interesting field. What do you have here?
