The M29W320DT has 4 erase region. Signed-off-by: Richard Retanubun --- My baseline is 2009.03-rc1. If there are STMicro/Numonyx guys on this mailing list, can you help provide a more 'generic' way of detection? this way the exception list does not have to grow a lot. drivers/mtd/cfi_flash.c | 5 +++-- 1 files changed, 3 insertions(+), 2 deletions(-) diff --git a/drivers/mtd/cfi_flash.c b/drivers/mtd/cfi_flash.c index a66feac..391d169 100644 --- a/drivers/mtd/cfi_flash.c +++ b/drivers/mtd/cfi_flash.c @@ -1806,8 +1806,9 @@ static void flash_fixup_stm(flash_info_t *info, struct cfi_qry *qry) if (qry->num_erase_regions > 1) { /* reverse geometry if top boot part */ if (info->cfi_version < 0x3131) { - /* CFI < 1.1, guess by device id (only M29W320ET now) */ - if (info->device_id == 0x2256) { + /* CFI < 1.1, guess by device id (M29W320{DT,ET} only) */ + if (info->device_id == 0x22CA || + info->device_id == 0x2256) { cfi_reverse_geometry(qry); } } -- 1.5.6.5
