  • 14d0a02a1   Rename TEXT_BASE into CONFIG_SYS_TEXT_BASE ... Browse Code »

    The change is currently needed to be able to remove the board
    configuration scripting from the top level Makefile and replace it by
    a simple, table driven script.

    Moving this configuration setting into the "CONFIG_*" name space is
    also desirable because it is needed if we ever should move forward to
    a Kconfig driven configuration system.

  • 03b7004dd   Create CPUDIR variable ... Browse Code »

    The CPUDIR variable points to the location of a target's CPU directory.
    Currently, it is set to cpu/$CPU. However, using $CPUDIR will allow for
    more flexibility in the future. It lays the groundwork for reorganizing
    U-Boot's directory structure to support a layout such as:

    arch/$ARCH/cpu/$CPU/* (architecture with multiple CPU types)
    arch/$ARCH/cpu/* (architecture with one CPU type)

    Refactoring the OneNAND IPL code

    and some minor fixed:
    - Remove unnecessary header file
    - Fix wrong access at read interrupt
    - The recent OneNAND has 4KiB pagesize

    Also Board can override OneNAND IPL image

  • 1aada9cd6   Fix all linker scripts for older binutils versions (pre-2.16) ... Browse Code »

    Commit f62fb99941c6 fixed handling of all rodata sections by using a
    wildcard combined with calls to ld's builtin functions SORT_BY_ALIGNMENT()
    and SORT_BY_NAME(). Unfortunately these functions were only
    introduced with biunutils version 2.16, so the modification broke
    building with all tool chains using older binutils.

    This patch makes it work again. This is done by omitting the use of
    these functions for such old tool chains. This will result in
    slightly larger target binaries, as the rodata sections are no longer
    in optimal order alignment-wise which reauls in unused gaps, but the
    effect was found to be insignificant - especially compared to the fact
    that you cannot build U-Boot at all in the current state.

    As ld seems to have no support for conditionals we run the linker
    script through the C preprocessor which can be easily used to remove
    the unwanted function calls.

    Note that the C preprocessor must be run with the "-ansi" (or a
    "-std=") option to make sure all the system-specific predefined
    macros outside the reserved namespace are suppressed. Otherise, cpp
    might for example substitute "powerpc" to "1", thus corrupting for
    example "OUTPUT_ARCH(powerpc)" etc.

  • 69bcabb51   Fix OneNAND ipl to read CONFIG_SYS_MONITOR_LEN ... Browse Code »

    Currently OneNAND initial program loader (ipl) reads only block 0 ie 128KB.
    However, u-boot image for apollon board is 195KB making the board
    unbootable with OneNAND.

    Fix ipl to read CONFIG_SYS_MONITOR_LEN.
    CONFIG_SYS_MONITOR_LEN macro holds the U-Boot image size.

  • 196c74311   Reduce OneNAND IPL common code ... Browse Code »

    OneNAND IPL has common codes for RAM init, load data, and jump to 2nd
    bootloader, but it's common code used about 300~400 bytes. So board
    specific codes, such as lowlevel_init, can't has enough code. It make
    a difficult to implement OneNAND IPL.

    his patch make this common code as small as possible. and give
    lowlevel_init can have more codes.

  • f62fb9994   Fix all linker script to handle all rodata sections ... Browse Code »

    A recent gcc added a new unaligned rodata section called '.rodata.str1.1',
    which needs to be added the the linker script. Instead of just adding this
    one section, we use a wildcard ".rodata*" to get all rodata linker section
    gcc has now and might add in the future.

    However, '*(.rodata*)' by itself will result in sub-optimal section
    ordering. The sections will be sorted by object file, which causes extra
    padding between the unaligned rodata.str.1.1 of one object file and the
    aligned rodata of the next object file. This is easy to fix by using the
    SORT_BY_ALIGNMENT command.

    This patch has not be tested one most of the boards modified. Some boards
    have a linker script that looks something like this:

    *(.text)
    . = ALIGN(16);
    *(.rodata)
    *(.rodata.str1.4)
    *(.eh_frame)

    I change this to:

    *(.text)
    . = ALIGN(16);
    *(.eh_frame)
    *(SORT_BY_ALIGNMENT(SORT_BY_NAME(.rodata*)))

    This means the start of rodata will no longer be 16 bytes aligned.
    However, the boundary between text and rodata/eh_frame is still aligned to
    16 bytes, which is what I think the real purpose of the ALIGN call is.

  • 1bb707c39   Add Flex-OneNAND booting support ... Browse Code »

    Flex-OneNAND is a monolithic integrated circuit with a NAND Flash array
    using a NOR Flash interface. This on-chip integration enables system designers
    to reduce external system logic and use high-density NAND Flash
    in applications that would otherwise have to use more NOR components.

    Flex-OneNAND enables users to configure to partition it into SLC and MLC areas
    in more flexible way. While MLC area of Flex-OneNAND can be used to store data
    that require low reliability and high density, SLC area of Flex-OneNAND
    to store data that need high reliability and high performance. Flex-OneNAND
    can let users take advantage of storing these two different types of data
    into one chip, which is making Flex-OneNAND more cost- and space-effective.

  • 751b9b518   OneNAND Initial Program Loader (IPL) support ... Browse Code »

    This patch enables the OneNAND boot within U-Boot.
    Before this work, we used another OneNAND IPL called X-Loader based
    on open source. With this work, we can build the oneboot.bin image
    without other program.

    The build sequence is simple.
    First, it compiles the u-boot.bin
    Second, it compiles OneNAND IPL
    Finally, it becomes the oneboot.bin from OneNAND IPL and u-boot.bin
    The mechanism is similar with NAND boot except it boots from itself.

    Another thing is that you can only use the OneNAND IPL only to work
    other bootloader such as RedBoot and so on.
