* mtd: nand: omap: add support for BCH16_ECC - NAND driver updatespekon gupta2014-06-06-0/+8
| | | | | | | | | | | | | | | | | | This patch add support for BCH16_ECC to omap_gpmc driver. *need to BCH16 ECC scheme* With newer SLC Flash technologies and MLC NAND, and large densities, pagesizes Flash devices have become more suspectible to bit-flips. Thus stronger ECC schemes are required for protecting the data. But stronger ECC schemes have come with larger-sized ECC syndromes which require more space in OOB/Spare. This puts constrains like; (a) BCH16_ECC can correct 16 bit-flips per 512Bytes of data. (b) BCH16_ECC generates 26-bytes of ECC syndrome / 512B. Due to (b) this scheme can only be used with NAND devices which have enough OOB to satisfy following equation: OOBsize per page >= 26 * (page-size / 512) Signed-off-by: Pekon Gupta <pekon@ti.com>

* mtd: nand: fix GET/SET_FEATURES address on 16-bit devicesDavid Mosberger2014-06-06-1/+10
| | | | | | | | | | | | | | | | | | | | | | | | | As per following Sections in ONFI Spec, GET_FEATURES and SET_FEATURES also need byte-addressing on 16-bit devices. *Section: Target Initialization" "The Read ID and Read Parameter Page commands only use the lower 8-bits of the data bus. The host shall not issue commands that use a word data width on x16 devices until the host determines the device supports a 16-bit data bus width in the parameter page." *Section: Bus Width Requirements* "When the host supports a 16-bit bus width, only data is transferred at the 16-bit width. All address and command line transfers shall use only the lower 8-bits of the data bus. During command transfers, the host may place any value on the upper 8-bits of the data bus. During address transfers, the host shall set the upper 8-bits of the data bus to 00h."

* mtd: nand: force NAND_CMD_READID onto 8-bit busBrian Norris2014-06-06-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As per following Sections in ONFI Spec, NAND_CMD_READID should use only lower 8-bit for transfering command, address and data even on x16 NAND device. *Section: Target Initialization" "The Read ID and Read Parameter Page commands only use the lower 8-bits of the data bus. The host shall not issue commands that use a word data width on x16 devices until the host determines the device supports a 16-bit data bus width in the parameter page." *Section: Bus Width Requirements* "When the host supports a 16-bit bus width, only data is transferred at the 16-bit width.

During address transfers, the host shall set the upper 8-bits of the data bus to 00h." Thus porting following commit from linux-kernel to ensure that column address is not altered to align to x16 bus when issuing NAND_CMD_READID command. commit 3dad2344e92c6e1aeae42df1c4824f307c51bcc7 mtd: nand: force NAND_CMD_READID onto 8-bit bus Author: Brian Norris <computersforpeace@gmail.com> (preserving authorship) The NAND command helpers tend to automatically shift the column address for x16 bus devices, since most commands expect a word address, not a byte address. The Read ID command, however, expects an 8-bit address (i.e., 0x00, 0x20, or 0x40 should not be translated to 0x00, 0x10, or 0x20). This fixes the column address for a few drivers which imitate the nand_base defaults. Signed-off-by: Pekon Gupta <pekon@ti.com>

* mtd: move & update nand_ecclayout structure (plus board changes)Prabhakar Kushwaha2013-11-21-0/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | nand_ecclayout is present in mtd.h at Linux. Move this structure to mtd.h to comply with Linux. Also, increase the ecc placement locations to 640 to suport device having writesize/oobsize of 8KB/640B. This means that the maximum oobsize has gone up to 640 bytes and consequently the maximum ecc placement locations have also gone up to 640. Changes from Prabhabkar's version (squashed into one patch to preserve bisectability): - Added _LARGE to MTD_MAX_*_ENTRIES This makes the names match current Linux source, and resolves a conflict between http://patchwork.ozlabs.org/patch/280488/ and http://patchwork.ozlabs.org/patch/284513/ The former was posted first and is closer to matching Linux, but unlike Linux it does not add _LARGE to the names. The second adds _LARGE to one of the names, and depends on it in a subsequent patch (http://patchwork.ozlabs.org/patch/284512/). - Made max oobfree/eccpos configurable, and used this on tricorder, alpr, ASH405, T4160QDS, and T4240QDS (these boards failed to build for me without doing so, due to a size increase). On tricorder SPL, this saves 2576 bytes (and makes the SPL build again) versus the new default of 640 eccpos and 32 oobfree, and saves 336 bytes versus the old default of 128 eccpos and 8 oobfree.

* mtd: driver _read() returns max_bitflips; mtd_read() returns -EUCLEANPaul Burton2013-10-09-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Linux modified the MTD driver interface in commit edbc4540 (with the same name as this commit). The effect is that calls to mtd_read will not return -EUCLEAN if the number of ECC-corrected bit errors is below a certain threshold, which defaults to the strength of the ECC. This allows -EUCLEAN to stop indicating "some bits were corrected" and begin indicating "a large number of bits were corrected, the data held in this region of flash may be lost soon". UBI makes use of this and when -EUCLEAN is returned from mtd_read it will move data to another block of flash. Without adopting this interface change UBI on U-boot attempts to move data between blocks every time a single bit is corrected using the ECC, which is a very common occurance on some devices. For some devices where bit errors are common enough, UBI can get stuck constantly moving data around because each block it attempts to use has a single bit error. This condition is hit when wear_leveling_worker attempts to move data from one PEB to another in response to an -EUCLEAN/UBI_IO_BITFLIPS error. When this happens ubi_eba_copy_leb is called to perform the data copy, and after the data is written it is read back to check its validity. If that read returns UBI_IO_BITFLIPS (in response to an MTD -EUCLEAN) then ubi_eba_copy_leb returns 1 to wear_leveling worker, which then proceeds to schedule the destination PEB for erasure. This leads to erase_worker running on the PEB, and following a successful erase wear_leveling_worker is called which begins this whole cycle all over again. The end result is that (without UBI debug output enabled) the boot appears to simply hang whilst in reality U-boot busily works away at destroying a block of the NAND flash. Debug output from this situation: UBI DBG: ensure_wear_leveling: schedule scrubbing UBI DBG: wear_leveling_worker: scrub PEB 1027 to PEB 4083 UBI DBG: ubi_io_read_vid_hdr: read VID header from PEB 1027 UBI DBG: ubi_io_read: read 4096 bytes from PEB 1027:4096 UBI DBG: ubi_eba_copy_leb: copy LEB 0:0, PEB 1027 to PEB 4083 UBI DBG: ubi_eba_copy_leb: read 1040384 bytes of data UBI DBG: ubi_io_read: read 1040384 bytes from PEB 1027:8192 UBI: fixable bit-flip detected at PEB 1027 UBI DBG: ubi_io_write_vid_hdr: write VID header to PEB 4083 UBI DBG: ubi_io_write: write 4096 bytes to PEB 4083:4096 UBI DBG: ubi_io_read_vid_hdr: read VID header from PEB 4083 UBI DBG: ubi_io_read: read 4096 bytes from PEB 4083:4096 UBI DBG: ubi_io_write: write 4096 bytes to PEB 4083:8192 UBI DBG: ubi_io_read: read 4096 bytes from PEB 4083:8192 UBI: fixable bit-flip detected at PEB 4083 UBI DBG: schedule_erase: schedule erasure of PEB 4083, EC 55, torture 0 UBI DBG: erase_worker: erase PEB 4083 EC 55 UBI DBG: sync_erase: erase PEB 4083, old EC 55 UBI DBG: do_sync_erase: erase PEB 4083 UBI DBG: sync_erase: erased PEB 4083, new EC 56 UBI DBG: ubi_io_write_ec_hdr: write EC header to PEB 4083 UBI DBG: ubi_io_write: write 4096 bytes to PEB 4083:0 UBI DBG: ensure_wear_leveling: schedule scrubbing UBI DBG: wear_leveling_worker: scrub PEB 1027 to PEB 4083 ... This patch adopts the interface change as in Linux commit edbc4540 in order to avoid such situations. Given that none of the drivers under drivers/mtd return -EUCLEAN, this should only affect those using software ECC. I have tested that it works on a board which is currently out of tree, but which I hope to be able to begin upstreaming soon.

* | mtd: nand: add driver for diskonchip g4 nand flashMike Dunn2013-05-05-0/+134
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a driver for the diskonchip G4 nand flash device. It is based on the driver from the linux kernel. This also includes a separate SPL driver. A separate SPL driver is used because the device operates in a different mode (reliable mode) when loading a boot image, and also because the storage format of the boot image is different from normal data (pages are stored redundantly). The SPL driver basically mimics how a typical IPL reads data from the device. The special operating mode and storage format are used to compensate for the fact that the IPL does not contain the BCH ecc decoding algorithm (due to size constraints). Although the u-boot SPL *could* use ecc, it operates like an IPL for the sake of simplicity and uniformity, since the IPL and SPL share the task of loading the u-boot image. As a side benefit, the SPL driver is very small. [port from linux kernel 3.4 commit 570469f3bde7f71cc1ece07a18d54a05b6a8775d] Signed-off-by: Mike Dunn <mikedunn@newsguy.com>
* | lib: import bitrev library from the linux kernelMike Dunn2013-05-05-0/+23
|/ | | | | | | | | | | This patch adds the bitrev library from the linux kernel. This is a simple algorithm that uses an 8 bit look-up table to reverse the bits in data types of 8, 16, or 32 bit widths. The docg4 nand flash driver uses it. [port from linux kernel v3.9 commit 7ee32a6d30d1c8a3b7a07a6269da8f0a08662927] [originally added: v2.6.20 by commit a5cfc1ec58a07074dacb6aa8c79eff864c966d12] Signed-off-by: Mike Dunn <mikedunn@newsguy.com>
* Consolidate bool typeYork Sun2013-04-01-4/+5
| | | | | | | | | | | | | 'bool' is defined in random places. This patch consolidates them into a single header file include/linux/types.h, using stdbool.h introduced in C99. All other #define, typedef and enum are removed. They are all consistent with true = 1, false = 0. Replace FALSE, False with false. Replace TRUE, True with true. Skip *.py, *.php, lib/* files.

* Make linux kernel string funcs available to toolsJoe Hershberger2012-12-13-4/+9
| | | | | | | | | | isspace() and strim() are not in the typical user-mode string.h, so put them in a separate compilation unit so that they can be built into tools that need them independent of the other common string functions. This allows code shared by u-boot and the linux user-mode tools to link. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>
* Add strcasecmp() and strncasecmp()Simon Glass2012-12-11-2/+5
| | | | | | | | | | | strncasecmp() is present as strnicmp() but disabled. Make it available and define strcasecmp() also. There is a only a small performance penalty to having strcasecmp() call strncasecmp(), so do this instead of a standalone function, to save code space. Update the prototype in arch-specific headers as needed to avoid warnings. Signed-off-by: Simon Glass <sjg@chromium.org>

* | musb-new: port of Linux musb driverIlya Yanok2012-11-20-0/+162
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Existing U-Boot musb driver has no support for the new gadget framework and also seems to have other limitations. As gadget framework is ported from Linux it seems pretty natural to port musb gadget driver as well. This driver supports both host and peripheral modes. This is not a replacement for current musb driver (at least now) as there are still some consumers of the old UDC interface. No DMA operation support included, CONFIG_MUSB_PIO_ONLY should be defined. Virtual root hub device is not implemented. Known problems: with no devices connected usb_lowlevel_start() fails. Signed-off-by: Ilya Yanok <ilya.yanok@cogentembedded.com>
