  • 2acc24fc2   Kconfig: Migrate BOUNCE_BUFFER ... Browse Code »

    The bounce buffer is used by a few drivers (most of the MMC drivers)
    to overcome limitations in their respective DMA implementation.

    This moves the configuration to Kconfig and makes it user-selectable
    (even though it will be a required feature to make those drivers
    work): the expected usage is for drivers depending on this to 'select'
    it unconditionally from their respective Kconfig (see follow-up
    patches).

    This commit includes a full migration using moveconfig.py to ensure
    that each commit compiles. To ensure bisectability we update
    dependencies of various drivers to now select BOUNCE_BUFFER when needed.

    [trini: Squash all patches to ensure bisectability]

  • c7b3a7ee5   optee: adjust dependencies and default values for dram ... Browse Code »
    12

    We may have, the not yet considered, scenario where OPTEE is loaded before
    u-boot and *not* by u-boot, e.g, the boot flow using the ARM Trusted
    Firmware (ATF), where in the 32bit flow is:
    BootRom->ATF(BL2)->Optee(BL32)->u-boot(BL33)

    In this case we need still to reserve the memory used by optee, to avoid
    for example to realocate ourself to the same address at the end of DRAM.
    So, we change here the dependencies on the OPTEE lib and we set the default
    size and base of TZRAM to zero.

    We have the following cases:
    - CONFIG_NR_DRAM_BANKS was defined, migrate normally
    - CONFIG_NR_DRAM_BANKS_MAX was defined and then used for
    CONFIG_NR_DRAM_BANKS after a check, just migrate it over now.
    - CONFIG_NR_DRAM_BANKS was very oddly defined on p2771-0000-* (to 1024 +
    2), set this to 8.

  • 4bcbfcf45   warp7: Specify CONFIG_OPTEE_LOAD_ADDR ... Browse Code »

    In order to sign images with the IMX code-signing-tool (CST) we need to
    know the load address of a given image. The best way to derive this load
    address is to make it into a define - so that u-boot.cfg contains the
    address - which we can then parse when generating the IMX CST headers.

    This patch makes the OPTEE_LOAD_ADDR available via u-boot.cfg for further
    parsing by external tools.

    On the NIOS2 and Xtensa architectures, we do not have
    CONFIG_SYS_TEXT_BASE set. This is a strict migration of the current
    values into the defconfig and removing them from the headers.

    I did not attempt to add more default values in and for now will leave
    that to maintainers.

  • ad12dc184   cmd: Toggle the default value of CONFIG_CMD_IMLS ... Browse Code »

    Having this as a 'default y' is rather annoying because it doesn't
    actually compile unless other options are defined in the board header:

    ../cmd/bootm.c: In function 'do_imls_nor':
    ../cmd/bootm.c:330:7: error: 'CONFIG_SYS_MAX_FLASH_BANKS' undeclared (first use in this function); did you mean 'CONFIG_SYS_MAX_FLASH_SECT'?
    i < CONFIG_SYS_MAX_FLASH_BANKS; ++i, ++info) {

    Make it 'default n' so people who develop new boards that start from a
    blank defconfig have one less compilation failure to debug.
