  • a09fea1d2   env: Finish migration of common ENV options ... Browse Code »
    1

    - In ARMv8 NXP Layerscape platforms we also need to make use of
    CONFIG_SYS_RELOC_GD_ENV_ADDR now, do so.
    - On ENV_IS_IN_REMOTE, CONFIG_ENV_OFFSET is never used, drop the define
    to 0.
    - Add Kconfig entry for ENV_ADDR.
    - Make ENV_ADDR / ENV_OFFSET depend on the env locations that use it.
    - Add ENV_xxx_REDUND options that depend on their primary option and
    SYS_REDUNDAND_ENVIRONMENT
    - On a number of PowerPC platforms, use SPL_ENV_ADDR not CONFIG_ENV_ADDR
    for the pre-main-U-Boot environment location.
    - On ENV_IS_IN_SPI_FLASH, check not for CONFIG_ENV_ADDR being set but
    rather it being non-zero, as it will now be zero by default.
    - Rework the env_offset absolute in env/embedded.o to not use
    CONFIG_ENV_OFFSET as it was the only use of ENV_OFFSET within
    ENV_IS_IN_FLASH.
    - Migrate all platforms.

  • 8d8ee47e0   env: Add CONFIG_SYS_RELOC_GD_ENV_ADDR symbol ... Browse Code »
    24

    Today in initr_reloc_global_data() we use some non-obvious tests to
    determine if we need to relocate the env_addr within gd or not. In
    order to facilitate migration of other symbols to Kconfig we need to
    introduce a new symbol for this particular use case.

  • 86cf1c828   configs: Migrate CONFIG_NR_DRAM_BANKS ... Browse Code »
    13

    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.

  • 1d6c54ecb   arm: zynqmp: Add ZynqMP minimal R5 support ... Browse Code »

    Xilinx ZynqMP also contains dual Cortex R5 which can run U-Boot.
    This patch is adding minimal support to get U-Boot boot.
    U-Boot on R5 runs out of DDR with default configuration that's why
    DDR needs to be partitioned if there is something else running on arm64.
    Console is done via Cadence uart driver and the first Cadence Triple
    Timer Counter is used for time.

    This configuration with uart1 was tested on zcu100-revC.

    U-Boot 2018.05-rc2-00021-gd058a08d907d (Apr 18 2018 - 14:11:27 +0200)

    Model: Xilinx ZynqMP R5
    DRAM: 512 MiB
    WARNING: Caches not enabled
    MMC:
    In: serial@ff010000
    Out: serial@ff010000
    Err: serial@ff010000
    Net: Net Initialization Skipped
    No ethernet found.
    ZynqMP r5>

    There are two ways how to run this on ZynqMP.
    1. Run from ZynqMP arm64
    tftpb 20000000 u-boot-r5.elf
    setenv autostart no && bootelf -p 20000000
    cpu 4 disable && cpu 4 release 10000000 lockstep
    or
    cpu 4 disable && cpu 4 release 10000000 split

    2. Load via jtag when directly to R5
