  • 3aa29de0b   TPL : introduce the TPL based on the SPL ... Browse Code »

    Due to the nand SPL on some board(e.g. P1022DS)has a size limit, it can
    not be more than 4K. So, the SPL cannot initialize the DDR with the SPD
    code. This patch introduces TPL to enable a loader stub that is loaded
    by the code from the SPL. It initializes the DDR with the SPD or other
    operations.

    The TPL's size is sizeable, the maximum size is decided by the memory's
    size that TPL runs. It initializes the DDR through SPD code, and copys
    final uboot image to DDR. So there are three stage uboot images:
    * spl_boot, * tpl_boot, * final uboot image

    The code from the internal on-chip ROM. It loads the final uboot image
    into DDR, then jump to it to begin execution.

    The SPL's size is sizeable, the maximum size must not exceed the size of L2
    SRAM. It initializes the DDR through SPD code, and copys final uboot image
    to DDR. So there are two stage uboot images:
    * spl_boot, 96KB size. The env variables are copied to L2 SRAM, so that
    ddr spd code can get the interleaving mode setting in env. It loads
    final uboot image from offset 96KB.
    * final uboot image, size is variable depends on the functions enabled.

  • 39bc12ddc   SPL: Makefile: Build a separate autoconf.mk for SPL ... Browse Code »

    SPL defines CONFIG_SPL_BUILD but this does not percolate to the
    autoconf.mk Makefile. As a result the build breaks when
    CONFIG_SPL_BUILD is used in the board-specific include header file. With
    this, there is a possibility of having a CONFIG option defined in the
    header file but not defined in the Makefile causing all kinds of build
    failure and problems.

    It also messes things for up, for example, when one might want to
    undefine options to keep the SPL small and doesn't want to be stuck with
    the CONFIG options used for U-boot. Lastly, this also avoids defining
    special CONFIG_SPL_ variables for cases where some options are required
    in U-boot but not in SPL.

    We add a spl-autoconf.mk rule that is generated for SPL with the
    CONFIG_SPL_BUILD flag and conditionally include it for SPL builds.

  • 8870e4599   imx: Move some i.MX common functions into the imx-common directory ... Browse Code »

    This patch moves the following functions into the imx-common
    directory:

    - mxs_wait_mask_set()
    - mxs_wait_mask_clr()
    - mxs_reset_block()

    These are currently used by i.MX28. But the upcoming GPMI NAND port
    for i.MX6 will also use these functions. So lets move them to a
    common location to re-use them.

  • ef123c525   Refactor linker-generated arrays ... Browse Code »

    Refactor linker-generated array code so that symbols
    which were previously linker-generated are now compiler-
    generated. This causes relocation records of type
    R_ARM_ABS32 to become R_ARM_RELATIVE, which makes
    code which uses LGA able to run before relocation as
    well as after.

    Note: this affects more than ARM targets, as linker-
    lists span possibly all target architectures, notably
    PowerPC.

    Remove them whenever possible; keep it only in the seven am335x_evm
    variants (am335x_evm, am335x_evm_uart[1-5], am335x_evm_spiboot),

  • 97b24d3d5   common: Add symbol handling for generic lists into Makefile ... Browse Code »

    This patch adds essential components for generation of the contents of
    the linker section that is used by the linker-generated array. All of
    the contents is held in a separate file, u-boot.lst, which is generated
    at runtime just before U-Boot is linked.

    The purpose of this code is to especially generate the appropriate
    boundary symbols around each subsection in the section carrying the
    linker-generated arrays. Obviously, the interim linker code for actual
    placement of the variables into the section is generated too. The
    generated file, u-boot.lst, is included into u-boot.lds via the linker
    INCLUDE directive in u-boot.lds .

    Adjustments are made in the Makefile and spl/Makefile so that the
    u-boot.lds and u-boot-spl.lds depend on their respective .lst files.

    Move files that are going to be common between T20 and T30 into 'tegra-common'
    subdirs in AVP (arm720t), CPU (armv7), and shared (arch/arm/cpu/.) areas. Any
    files that are left behind in '/tegra20' will be copied to '/tegra30' subdirs
    and modified for that SoC. The 'common' files should need only minor changes.

    Include files (arch/arm/include/asm/arch-tegra/tegra20) will be done in a
    follow-on patch.

    Builds fine w/MAKEALL -s tegra20. Checkpatch.pl is clean.

  • 7ac2fe2da   OMAP: networking support for SPL ... Browse Code »

    This patch adds support for networking in SPL. Some devices are
    capable of loading SPL via network so it makes sense to load the
    main U-Boot binary via network too. This patch tries to use
    existing network code as much as possible. Unfortunately, it depends
    on environment which in turn depends on other code so SPL size
    is increased significantly. No effort was done to decouple network
    code and environment so far.

    Add a new flag, CONFIG_SPL_FRAMEWORK to opt into the common/spl SPL
    framework, enable on all of the previously using boards. We move the
    spl_ymodem.c portion to common/ and spl_mmc.c to drivers/mmc/. We leave
    the NAND one in-place as we plan to replace it later in this series.

    We use common/spl to avoid linker problems with respect to merging
    constant strings in objects. Otherwise all strings in common/ will be
    linked in and kept which grows SPL in size too much.

    Remove linker command line options from the SPL makefile
    that force the inclusion of unreferenced command code from
    linked object files. As commands are not used in the SPL,
    these options resulted in an unnecessary increase in the
    image size, in addition to introducing the possibility of
    tricky link errors in the case where the command code
    contained symbols that were not resolved by linking in the
    limited objects compiled in the SPL build.

    It's a dual core SOC with GIC used for interrupt handling and SCU for cache
    coherency.

    Also moved some part of code from the basic platform support that can be made

    for clocks and emif support in the subsequent patches.
