| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds a SPI flash driver which simulates SPI flash clients. Currently supports the bare min that U-Boot requires: you can probe, read, erase, and write. Should be easy to extend to make it behave more exactly like a real SPI flash, but this is good enough to merge now. sjg@chromium.org added a README and tidied up code a little. Added a required map_sysmem() for sandbox. Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Simon Glass <sjg@chromium.org>

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | Existing eSPI SPL framework assumes booting from spi-image with boot_format header which contains final u-boot Image offset and size. No such header is present in case of corenet devices like T1040 as corenet deivces use PBI-RCW based intialization. So, for corenet deives, SPL bootloader use values provided at compilation time. These values can be defined in board specific config file. Signed-off-by: Priyanka Jain <Priyanka.Jain@freescale.com> Acked-by: York Sun <yorksun@freescale.com>

* | mtd: nand: omap: add CONFIG_NAND_OMAP_ECCSCHEME for selection of ecc-schemepekon gupta2013-11-21-9/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds new CONFIG_NAND_OMAP_ECCSCHEME, replacing other distributed CONFIG_xx used for selecting NAND ecc-schemes. This patch aims at solving following issues. 1) Currently ecc-scheme is tied to SoC platform, which prevents user to select other ecc-schemes also supported in hardware. like; - most of OMAP3 SoC platforms use only 1-bit Hamming ecc-scheme, inspite the fact that they can use higher ecc-schemes like 8-bit ecc-schemes with software based error detection (OMAP_ECC_BCH4_CODE_HW_DETECTION_SW). - most of AM33xx SoC plaforms use 8-bit BCH ecc-scheme for now, but hardware supports BCH16 ecc-scheme also. 2) Different platforms use different CONFIG_xx to select ecc-schemes, which adds confusion for user while migrating platforms. - *CONFIG_NAND_OMAP_ELM* which enables ELM hardware engine, selects only 8-bit BCH ecc-scheme with h/w based error-correction (OMAP_ECC_BCH8_CODE_HW) whereas ELM hardware engine supports other ecc-schemes also like; BCH4, and BCH16 (in future). - *CONFIG_NAND_OMAP_BCH8* selects 8-bit BCH ecc-scheme with s/w based error correction (OMAP_ECC_BCH8_CODE_HW_DETECTION_SW). - *CONFIG_SPL_NAND_SOFTECC* selects 1-bit Hamming ecc-scheme using s/w library Thus adding new *CONFIG_NAND_OMAP_ECCSCHEME* de-couples ecc-scheme dependency on SoC platform and NAND driver. And user can select ecc-scheme independently foreach board. However, selection some hardware based ecc-schemes (OMAP_ECC_BCHx_CODE_HW) still depends on presence of ELM hardware engine on SoC.

* | mtd: move & update nand_ecclayout structure (plus board changes)Prabhakar Kushwaha2013-11-21-5/+10

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | as per controller description, "While programming a NAND flash, status read should never skipped. Because it may happen that a new command is issued to the NAND Flash, even when the device has not yet finished processing the previous request. This may result in unpredictable behaviour." IFC controller never polls for R/B signal after command send. It just return control to software. This behaviour may not occur with NAND flash access. because new commands are sent after polling R/B signal. But it may happen in scenario where GPCM-ASIC and NAND flash device are working simultaneously.

Resolution consists in adjusting the list of object files in the main branch version. This also applies to two files which are not listed as conflicting but had to be modified: board/compulab/common/Makefile board/udoo/Makefile include/configs/omap4_common.h conflicts are due to the OMAP4 conversion to ti_armv7_common.h on the ARM side, and CONFIG_SYS_HZ removal on the main side. Resolution is to convert as this icludes removal of CONFIG_SYS_HZ. include/configs/pdnb3.h is due to a removal on ARM side. Trivial resolution is to remove the file.

| * mtd: driver _read() returns max_bitflips; mtd_read() returns -EUCLEANPaul Burton2013-10-09-12/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
