  • fb4384490   mtd: Makefile: deep cleanup ... Browse Code »

    Move MTD-related lines out of the root Makefile. Put them in their
    respective directories. Enclose some of these new lines to skip them
    when building the SPL. MTD core files and some MTD device drivers are
    compiled in a mtd.o object and included in the final object only if
    MTD support is required (there are two different symbols for that, one
    for U-Boot and one for the SPL).

    Now that all defconfigs have been fixed, we can stop the logic where
    enabling a command selects the core files to compile. This logic is
    broken since selecting a symbol with a 'depends on' will not enforce
    this secondary dependency.

  • 7feafb0ae   ufs: Add Initial Support for UFS subsystem ... Browse Code »

    Add Support for UFS Host Controller Interface (UFSHCI) for communicating
    with Universal Flash Storage (UFS) devices. The steps to initialize the
    host controller interface are the following:

    - Initiate the Host Controller Initialization process by writing to the
    Host controller enable register.
    - Configure the Host Controller base address registers by allocating a
    host memory space and related data structures.
    - Unipro link startup procedure
    - Check for connected device
    - Configure UFS host controller to process requests

    Also register this host controller as a SCSI host controller.

    Taken from Linux Kernel v5.2 (drivers/scsi/ufs/ufshcd.c) and ported to
    U-boot.

  • a8b503110   spl: kconfig: separate sysreset and firmware drivers from misc ... Browse Code »

    This adds separate kconfig options for drivers/sysreset and
    drivers/firmware.

    Up to now, CONFIG_SPL_DRIVERS_MISC_SUPPORT added drivers/misc to SPL
    build but also added drivers/firmware and drivers/sysreset at the same
    time.

    Since that is confusing, this patch uses CONFIG_SPL_SYSRESET for
    drivers/sysreset and adds CONFIG_SPL_FIRMWARE for
    drivers/firmware (and accordingly for the TPL options).

    CONFIG_SPL_DRIVERS_MISC_SUPPORT stays for including drivers/misc into
    the SPL build (and accordingly for TPL) since there are boards using
    non-DM (non UCLASS_MISC) files from drivers/misc. Such boards don't
    have CONFIG_SPL_MISC enabled, so cannot use this to include
    drivers/misc into the SPL build.

  • 2d59ec848   dfu: Make DFU support more SPL friendly ... Browse Code »

    Do this by using $(SPL_) in Makefiles and CONFIG_IS_ENABLED in C code.
    This ensures the files and features are only built into the right build
    for which they are enabled. Using the macros to simplify this patch was
    made possible by the config symbol rename done in the last patch.

  • d50d6817b   spl: fix build failure with !CONFIG_SPL_PCI_SUPPORT ... Browse Code »

    Building U-Boot with CONFIG_PCI and CONFIG_DM_PCI enabled, but
    CONFIG_SPL_PCI_SUPPORT disabled, results in following linker
    error:

    lib/built-in.o: In function `fdtdec_get_pci_bar32':
    lib/fdtdec.c:305: undefined reference to `dm_pci_read_bar32'
    fdtdec.c:305:(.text.fdtdec_get_pci_bar32+0x24): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `dm_pci_read_bar32'

    This is because reference to dm_pci_read_bar32() remains in lib/fdtdec.c
    while SPL build does not descend into drivers/pci directory in
    drivers/Makefile if CONFIG_SPL_PCI_SUPPORT is not enabled.

    Fix this by applying appropriate #define guards in lib/fdtdec.c.
    It looks like ns16550.c has the same problem, so fixed that too.

    To simplify this, CONFIG_SPL_PCI_SUPPORT is renamed to CONFIG_SPL_PCI
    (enables use of CONFIG_IS_ENABLED() macro).

    1

    This adds a new virtio uclass driver for “virtio” [1] family of
    devices that are are found in virtual environments like QEMU,
    yet by design they look like physical devices to the guest.

    The uclass driver provides child_pre_probe() and child_post_probe()
    methods to do some common operations for virtio device drivers like
    device and driver supported feature negotiation, etc.

  • 9ff4a3117   Add UCLASS_TEE for Trusted Execution Environment ... Browse Code »

    Adds a uclass to interface with a TEE (Trusted Execution Environment).

    A TEE driver is a driver that interfaces with a trusted OS running in
    some secure environment, for example, TrustZone on ARM cpus, or a
    separate secure co-processor etc.

    The TEE subsystem can serve a TEE driver for a Global Platform compliant
    TEE, but it's not limited to only Global Platform TEEs.

    The over all design is based on the TEE subsystem in the Linux kernel,
    tailored for U-Boot.

  • 5381c2856   drivers: Add board uclass ... Browse Code »

    Since there is no canonical "board device" that can be used in board
    files, it is difficult to use DM function for board initialization in
    these cases.

    Hence, add a uclass that implements a simple "board device", which can
    hold devices not suitable anywhere else in the device tree, and is also
    able to read encoded information, e.g. hard-wired GPIOs on a GPIO
    expander, read-only memory ICs, etc. that carry information about the
    hardware.

    The devices of this uclass expose methods to read generic data types
    (integers, strings, booleans) to encode the information provided by the
    hardware.
