From: Sascha Silbe <sascha-pgp@xxxxxxxxx> The Marvell SDIO host controller can transmit Erase commands to the card quite fine. Signed-off-by: Sascha Silbe <sascha-pgp@xxxxxxxxx> --- drivers/mmc/host/mvsdio.c | 3 ++- 1 files changed, 2 insertions(+), 1 deletions(-) Tested on OpenRD-Base using a SanDisk 4GB class 4 card (retail). The BLKDISCARD ioctl returned immediately, no timeout issue encountered. I had to remove and reinsert the card to read the new (i.e. erased) data, but that's most likely either by design or a bug on a different layer. diff --git a/drivers/mmc/host/mvsdio.c b/drivers/mmc/host/mvsdio.c index eeb1147..758251d 100644 --- a/drivers/mmc/host/mvsdio.c +++ b/drivers/mmc/host/mvsdio.c @@ -735,7 +735,8 @@ static int __init mvsd_probe(struct platform_device *pdev) mmc->ocr_avail = MMC_VDD_32_33 | MMC_VDD_33_34; mmc->caps = MMC_CAP_4_BIT_DATA | MMC_CAP_SDIO_IRQ | - MMC_CAP_SD_HIGHSPEED | MMC_CAP_MMC_HIGHSPEED; + MMC_CAP_SD_HIGHSPEED | MMC_CAP_MMC_HIGHSPEED | + MMC_CAP_ERASE; mmc->f_min = DIV_ROUND_UP(host->base_clock, MVSD_BASE_DIV_MAX); mmc->f_max = maxfreq; -- 1.7.4.1 -- To unsubscribe from this list: send the line "unsubscribe linux-mmc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
