  • 4806fcea1   mtd: spi: Export spi_flash_std_probe() ... Browse Code »

    With of-platdata we need to create drivers for particular chips, or at
    least drivers that are separate from the standard code, since C structures
    are created by dtoc which are private to that driver.

    To avoid duplicating the probing code, export this probe function for use
    by these drivers.

  • abe66b1b5   Convert CONFIG_ENV_SPI_* to Kconfig ... Browse Code »
    24

    This converts the following to Kconfig:
    CONFIG_ENV_SPI_BUS
    CONFIG_ENV_SPI_CS
    CONFIG_ENV_SPI_MAX_HZ
    CONFIG_ENV_SPI_MODE

    Most of time these value are not needed, CONFIG_SF_DEFAULT
    with same value is used, so I introduced CONFIG_USE_ENV_SPI_*
    to force the associated value for the environment.

    I use moveconfig script and then manual check on generated u-boot.cfg
    to solve the remaining issue.

  • 83d290c56   SPDX: Convert all of our single license tags to Linux Kernel style ... Browse Code »
    56

    When U-Boot started using SPDX tags we were among the early adopters and
    there weren't a lot of other examples to borrow from. So we picked the
    area of the file that usually had a full license text and replaced it
    with an appropriate SPDX-License-Identifier: entry. Since then, the
    Linux Kernel has adopted SPDX tags and they place it as the very first
    line in a file (except where shebangs are used, then it's second line)
    and with slightly different comment styles than us.

    In part due to community overlap, in part due to better tag visibility
    and in part for other minor reasons, switch over to that style.

    This commit changes all instances where we have a single declared
    license in the tag as both the before and after are identical in tag
    contents. There's also a few places where I found we did not have a tag
    and have introduced one.

    removed the last usage of the spi_flash_probe_fdt function, rendering it

  • ea022a377   spi: Move freescale-specific code into a private header ... Browse Code »

    At present there are two SPI functions only used by freescale which are
    defined in the spi_flash.h header. One function name matches an existing
    generic SPL function.

    Move these into a private header to avoid confusion.

    Arcturus looks like it does not actually support SPI, so drop the SPI code
    from that board.

    commit c3c016c "sf: Add SPI NOR protection mechanism" introduced
    flash_lock()/flash_unlock()/flash_is_locked() methods for SPI flash,
    but not every flash driver supplies these. We should test these
    methods against NULL before actually calling them.

    34

    Many SPI flashes have protection bits (BP2, BP1 and BP0) in the
    status register that can protect selected regions of the SPI NOR.

    Take these bits into account when performing erase operations,
    making sure that the protected areas are skipped.

    Tested on a mx6qsabresd:

    => sf probe
    SF: Detected M25P32 with page size 256 Bytes, erase size 64 KiB, total 4 MiB
    => sf protect lock 0x3f0000 0x10000
    => sf erase 0x3f0000 0x10000
    offset 0x3f0000 is protected and cannot be erased
    SF: 65536 bytes @ 0x3f0000 Erased: ERROR
    => sf protect unlock 0x3f0000 0x10000
    => sf erase 0x3f0000 0x10000
    SF: 65536 bytes @ 0x3f0000 Erased: OK

  • 4c2dbefde   dm: sf: Add a uclass for SPI flash ... Browse Code »

    Add a driver model uclass for SPI flash which supports the common
    operations (read, write, erase). Since we must keep support for the
    non-dm interface, some modification of the spi_flash header is required.

    CONFIG_DM_SPI_FLASH is used to enable driver model for SPI flash.

  • 88e34e5ff   spl: replace CONFIG_SPL_SPI_* with CONFIG_SF_DEFAULT_* ... Browse Code »
    29

    Currently, CONFIG_SPL_SPI_* #defines are used for controlling SPI boot in
    SPL. These #defines do not allow the user to select SPI mode for the SPI flash
    (there's no CONFIG_SPL_SPI_MODE, so the SPI mode is hardcoded in
    spi_spl_load.c), and duplicate information already provided by
    CONFIG_SF_DEFAULT_* #defines.

    Kill CONFIG_SPL_SPI_*, and use CONFIG_SF_DEFAULT_* instead.
