* nand: reinstate lazy bad block scanningScott Wood2012-02-28-3/+7
| | | | | | | | | | | | | commit 2a8e0fc8b3dc31a3c571e439fbf04b882c8986be ("nand: Merge changes from Linux nand driver") accidentally reverted commit 13f0fd94e3cae6f8a0d9fba5d367e311edc8ebde ("NAND: Scan bad blocks lazily."). Reinstate the change, as amended by commit ff49ea8977b56916edd5b1766d9939010e30b181 ("NAND: Mark the BBT as scanned prior to calling scan_bbt."). Signed-off-by: Scott Wood <scottwood@freescale.com>
* Revert "nand: make 1-bit software ECC configurable"Scott Wood2012-02-28-5/+1
| | | | | | | | | | | | | | This reverts commit 4fee6c2f295f932b8febdc7ce8731ba045695fa5. It breaks boards that currently rely on soft-ecc, as pointed out here: http://patchwork.ozlabs.org/patch/140872/ The reverted patch should be resubmitted with documentation, and with the CONFIG_MTD_ECC_SOFT selected from every board that needs it. We could start by looking at what NAND driver the board selects, and whether that driver ever asks for soft ECC. Signed-off-by: Scott Wood <scottwood@freescale.com>

| | | | | | | | | | | | | | | | | | Align the card status polling with the Linux kernel and retry the command at least five times. Also some cards apparently mishandle the status bits, so make sure to check the card state too. Signed-off-by: Jan Kloetzke <jan.kloetzke@dspg.com> Cc: Andy Fleming <afleming@gmail.com>
| * mmc: fix card busy pollingJan Kloetzke2012-02-15-8/+6
| | | | | | | | | | | | | | | | | | | | | | | | A MMC/SD card may always go into the programming state (and hence be busy) after a block write. Therefore always check the card state, even after single block writes. On the other hand there is no need to check the card status after a read. Also make sure that errors during busy polling are propagated upwards. Signed-off-by: Jan Kloetzke <jan.kloetzke@dspg.com> Cc: Andy Fleming <afleming@gmail.com>
| * Tegra: mmc: Fixed handling of interrupts in timeouts.Tom Warren2012-02-15-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | We are seeing occasional timeouts in the Tegra mmc code when we are reading from external MMC cards. These don't seem to be detrimental if they are handled properly. This CL properly clears the "normal interrupt status register" (norintsts) in error conditions. If we don't do this, when we come back into mmc_send_cmd() the register will still contain status from the last transaction.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before we can send a command we need both the DATI (command inhibit on mmc_dat line) bit and CMDI (command inhibit on mmc_cmd line) are clear. The previous behavior of only checking on DATI was insufficient on some cards and incorrect behavior in any case. This makes the code check for both bits being clear and makes the error print more clear as to what happened. DATI_CMDDIS is removed as it was unused elsewhere in the code and stood for 'DATI is set, cmds are disabled still'. Fix originally spotted by Peter Bigot. Tested-by: Peter A.

* | mx28: fix i.MX28 spi driverMatthias Fuchs2012-02-12-3/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The generic spi flash driver (drivers/mtd/spi/spi_flash.c) uses the spi low level driver's spi_xfer() function with len=0 to deassert the SPI flash' chip select. But the i.MX28 spi driver rejects this call due to len=0. This patch implements an exception for len=0 with the SPI_XFER_END flag set. This results in an extra read with the chip select being deasserted afterwards. There seems to be no way to deassert the signal by hand.

Pins, base address and prototypes for an i.MX31 specific board_init_mmc() are provided. Some of the i.MX27 clock getters are unused and marked as such to avoid warnings (./MAKEALL -s mx27), but the code was left in for future use.

The reason is, udelay is never called, if flash device is ready to fast. e.g. mw.w $(copy_addr) FFFF 10000;cp.b $(copy_addr) 10880000 20000 -> watchdog timed out mw.w $(copy_addr) 0000 10000;cp.b $(copy_addr) 10880000 20000 -> watchdog not timed out This patch adds an extra watchdog reset in front of flash ready check.
