* nand: Add SPL_NAND support to mxc_nand_splMarek Vasut2013-05-05-3/+10
| | | | | | | | | | | | | | | | | | | | Add support for generic NAND SPL via the SPL framework into the mxc_nand_spl driver. This is basically just a simple rename and publication of the already implemented functions. To avoid the bare-bones functions getting in the way of the NAND_SPL, build them only if CONFIG_SPL_FRAMEWORK is not defined. Also make sure the requested payload is aligned to full pages, otherwise this simple driver fails to load the last page.

| | | | | | | | | | | | | | | | | | | | | | Rework the waiting for transfer completion loop condition to continue waiting until both Transfer Complete and DMA End interrupts occur. Checking of DLA bit in Present State register looks not needed in addition to interrupts status checking, so it can be removed from the condition. Also, DMA Error condition is added to the list of data errors, checked in the loop. Signed-off-by: Andrew Gabbasov <andrew_gabbasov@mentor.com>

| * spi: mxc_spi: Set master mode for all channelsFabio Estevam2013-04-13-8/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The glitch in the SPI clock line, which commit 3cea335c34 (spi: mxc_spi: Fix spi clock glitch durant reset) solved, is back now and itwas re-introduced by commit d36b39bf0d (spi: mxc_spi: Fix ECSPI reset handling). Actually the glitch is happening due to always toggling between slave mode and master mode by configuring the CHANNEL_MODE bits in this reset function. Since the spi driver only supports master mode, set the mode for all channels always to master mode in order to have a stable, "glitch-free" SPI clock line.

| * | nand: Extend nand_(read|write)_skip_bad with *actual and limit parametersTom Rini2013-04-10-8/+60
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We make these two functions take a size_t pointer to how much space was used on NAND to read or write the buffer (when reads/writes happen) so that bad blocks can be accounted for. We also make them take an loff_t limit on how much data can be read or written. This means that we can now catch the case of when writing to a partition would exceed the partition size due to bad blocks. To do this we also need to make check_skip_len count not just complete blocks used but partial ones as well. All callers of nand_(read|write)_skip_bad are adjusted to call these with the most sensible limits available. The changes were started by Pantelis and finished by Tom.

| * | dfu: Support larger than memory transfers.Pantelis Antoniou2013-04-10-89/+262
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously we didn't support upload/download larger than available memory. This is pretty bad when you have to update your root filesystem for example. This patch removes that limitation (and the crashes when you transfered any file larger than 4MB) by making raw image writes be done in chunks and making file maximum size be configurable. The sequence number is a 16 bit counter; make sure we handle rollover correctly. This fixes the wrong transfers for large (> 256MB) images. Also utilize a variable to handle initialization, so that we don't rely on just the counter sent by the host.

Addressing for 8 and 16 bits is almost identical except in the 16-bit case the LSB of the address is always 0. The confusion arose because the addresses in the datasheet for 16-bit mode are word addresses but this code assumed it was byte addresses. I have only been able to test this on our Octeon boards which use either an 8-bit or 16-bit bus. I have not tested the case where there's an 8-bit part on a 16-bit bus. This patch also adds some delays as suggested by Spansion. If a part can be both 8 and 16-bits, it forces it to work in 8-bit mode if an 8-bit bus is detected. Apart from the pulled changes, fixed few minor code cleanups and tested on 256M29EW, 512M29EW flashes.

This method works when NAND is the boot medium, but does not work if another boot medium is used. For example: booting from a SD card and then using NAND to store the environment variables, would lead to the following error: NAND bus width 16 instead 8 bit No NAND device found!!! 0 MiB Use CONFIG_SYS_NAND_BUSWIDTH_16BIT symbol to decide the bus width. If it is defined in the board file, then consider 16-bit NAND bus-width, otherwise assume 8-bit NAND is used. This also aligns with Documentation/devicetree/bindings/mtd/nand.txt, which states: nand-bus-width : 8 or 16 bus width if not present 8 Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> Acked-by: Scott Wood <scottwood@freescale.com> Reviewed-by: Benoît Thébaudeau <benoit.thebaudeau@advansee.com>

This implementation uses the same layout for BCH8 but it is fix. The current provided layout does only work with 64 Byte OOB.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With uppcoming BCH support on OMAP devices we need to decide between differnt algorithms when switching the ECC engine. Currently we support 1-bit hammign and 8-bit BCH on HW backend. In order to switch between differnet ECC algorithms we need to change the interface of omap_nand_switch_ecc() also.

Therefore, disable the feature for now, until the driver adds the support. One usecase which is broken because of this feature is that Ether gadget stops working in Fullspeed mode (by un-defining CONFIG_USB_GADGET_DUALSPEED) After desabled this feature, MUSB driver send packets in proper size (no more than 64 bytes) in Fullspeed mode. This has been validated with Ether gadget in Fullspeed mode on AM335x EVM. Signed-off-by: Bin Liu <b-liu@ti.com>
