| * | mtd: pxa3xx_nand: introduce default timing to reduce read id timesLei Wen2010-10-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We certainly don't need to send read id command times by times, since we already know what the id is after the first read id... So create a default timing which could ensure it would successfully read id out all supported chip. Then follow the build-in table to reconfigure the timing.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adding a new flash definition would need less code. Keep the platform passing flash definition method. If one flash is both defined in platform data and builtin table, driver would select the one from platform data first. By this way, platform could select the timing most suit for itself, not need to follow the common settings.

| * | mtd: nand: support new Toshiba SLCBrian Norris2010-10-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Toshiba does not use ONFI for their NAND flash. So we have to continue to add new IDs used by Toshiba devices as well as heuristic detection for scanning the 2nd page for a BBM. This is a relatively harmless start at supporting many of them. These chips mostly follow the same ID fields of previous generations, but there is a need for a tweak. These chips introduce a strange 576 byte OOB (that's 36 bytes per 512 bytes of page). In the preliminary data, Toshiba has not defined exactly how their ID strings should decode. In the future, a new tweak must be added.

| * | mtd: nand: expand nand_ecc_layout, deprecate ioctl ECCGETLAYOUTBrian Norris2010-10-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | struct nand_ecclayout is too small for many new chips; OOB regions can be as large as 448 bytes and may increase more in the future. Thus, copying that struct to user-space with the ECCGETLAYOUT ioctl is not a good idea; the ioctl would have to be updated every time there's a change to the current largest size. Instead, the old nand_ecclayout is renamed to nand_ecclayout_user and a new struct nand_ecclayout is created that can accomodate larger sizes and expand without affecting the user-space. struct nand_ecclayout can still be used in board drivers without modification -- at least for now. A new function is provided to convert from the new to the old in order to allow the deprecated ioctl to continue to work with truncated data. Perhaps the ioctl, the conversion process, and the struct nand_ecclayout_user can be removed altogether in the future. Note: There are comments in nand/davinci_nand.c::nand_davinci_probe() regarding this issue; this driver (and maybe others) can be updated to account for extra space. All kernel drivers can use the expanded nand_ecclayout as a drop-in replacement and ignore its benefits.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some Spansion chips have a method for determining eraseblock size that is incompatible with similar ID chips of other sizes. This implements some heuristic detection of these differences.

Earlier, AEMIF configuration was being done as a special case for DM644x board, but now more boards emerge which have capability to boot for other media (SPI flash, NOR flash) and have the kernel access NAND flash. This means that kernel cannot always depend on the bootloader to setup the NAND. Also, on platforms such as da850/omap-l138, the aemif input frequency changes as cpu frequency changes; necessiating re-calculation of timimg values as part of cpufreq transtitions. This patch forms the basis for adding that support.

Since this capability is useful both from NOR and NAND flashes, it is provided as a new interface and in a file of its own. AEMIF timing configuration is required in cases: 1) Where the AEMIF clock rate can change at runtime (a side affect of cpu frequency change). 2) Where U-Boot does not support NAND/NOR but supports other media like SPI Flash or MMC/SD and thus does not care about setting up the AEMIF timing for kernel to use. 3) Where U-Boot just hasn't configured the timing values and cannot be upgraded because the box is already in the field. Since there is now a header file for AEMIF interface, the common (non-NAND specific) defines for AEMIF registers have been moved from nand.h into the newly created aemif.h Signed-off-by: Sekhar Nori <nsekhar@ti.com> Acked-by: Kevin Hilman <khilman@deeprootsystems.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>

| |/ / |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch reverts the driver to enabling/disabling the NFC interrupt mask rather than enabling/disabling the system interrupt. This cleans up the driver so that it doesn't rely on interrupts being disabled within the interrupt handler. For i.MX21 we keep the current behaviour, that is calling enable_irq/disable_irq_nosync to enable/disable interrupts. This patch is based on earlier work by John Ogness.

After checking the commit log, I found the problem is introduced by commit 5b0d4d7c8a67c5ba3d35e6ceb0c5530cc6846db7 "[MTD] [NAND] pxa3xx: convert from ns to clock ticks more accurately" To get num of clock cycles, we use below equation: num of clock cycles = time (ns) / one clock cycle (ns) + 1 We need to add 1 cycle here because integer division will truncate the result. It is possible the developers set the Min values in SPEC for timing settings. Thus the truncate may cause problem, and it is safe to add an extra cycle here. The various fields in NDTR{01} are in units of clock ticks minus one, thus we should subtract 1 cycle then. Thus the correct equation should be: num of clock cycles = time (ns) / one clock cycle (ns) + 1 - 1 = time (ns) / one clock cycle (ns) Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Lei Wen <leiwen@marvell.com> Acked-by: Eric Miao <eric.y.miao@gmail.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com> Cc: stable@kernel.org

| | | | | | | | | | | | | | | | | | | | | | | | | | | Nand devices with at least 26 bytes of oob data per 512 byte block can have 8bit ecc on v2 type controllers. This is currently not tested, but at least this patch puts the ECC_MODE bit into a well defined state.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The v2 controller has a totally different mechanism to check whether the data we read had ecc errors or not. Implement this. The mechanism in the v2 controller happens to be identical to the v3 controller. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This prepares the driver for v3 support. The v3 controller has a completely different register layout, so add a V1_V2_ namespace to the register defines to avoid confusion with the v3 regs.

| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch prepares the driver to add v3 controller support later.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We save/restore the value in the buffer anyway, so it makes no difference whether we use main_area0 or main_area1. So, we can use main_area0 and remove main_area1 from the driver which is otherwise unused. Also, clean up the comments in get_dev_status.
