  • The top level Makefile does not do any recursion into subdirs when
    cleaning, so these clean/distclean targets in random arch/board dirs
    never get used. Punt them all.

    MAKEALL didn't report any errors related to this that I could see.

  • Before this commit, weak symbols were not overridden by non-weak symbols
    found in archive libraries when linking with recent versions of
    binutils. As stated in the System V ABI, "the link editor does not
    extract archive members to resolve undefined weak symbols".

    This commit changes all Makefiles to use partial linking (ld -r) instead
    of creating library archives, which forces all symbols to participate in
    linking, allowing non-weak symbols to override weak symbols as intended.
    This approach is also used by Linux, from which the gmake function
    cmd_link_o_target (defined in config.mk and used in all Makefiles) is
    inspired.

    The name of each former library archive is preserved except for
    extensions which change from ".a" to ".o". This commit updates
    references accordingly where needed, in particular in some linker
    scripts.

    This commit reveals board configurations that exclude some features but
    include source files that depend these disabled features in the build,
    resulting in undefined symbols. Known such cases include:
    - disabling CMD_NET but not CMD_NFS;
    - enabling CONFIG_OF_LIBFDT but not CONFIG_QE.

  • This patch changes implementation of 'display' command for a4m072
    that uses 7-segment LED display as customer requested:

    a) The "display" command shall _not_ turn on the decimal point.

    b) Exception: "display ." shall turn on (only) the decimal point.

    c) Hex digits (0-9, A-F, a-f) shall be displayed as usual.

    d) Letters U, P, Y, L, S, T, H shall be displayed as usual (lower
    case letters identical to upper case letters)

    e) 'I' (and 'i') shall be displayed like '1'

    f) 'O' (and 'o') shall be displayed like '0'

    g) all other Characters shall be displayed like ' ' (all segments off).

  • This patch adds support for displaying boot progress codes on a4m072 board
    using LED display. As we can display only one symbol at any time on the hardware
    (two symbols with blinking) we can't display progress codes directly and have
    to map them to 2-symbol codes.
    We use the following mapping on the a4m972 board:
    [1, 8] U [100, 108] -> 5
    [-9, -1] U [-101, -100] U [-113, -103] -> -5
    [9, 14] U [120, 123] U [125, 129] -> 8
    [-13, -10] U [-122, -120] U [-127, -124] U {-129} -> -8
    {15} -> 9
    [-32, -30] -> -A
    [-40, -35] U [-51, -42] U [-58, -53] U
    [-83, -80] U {-64, -130, -140, -150} -> -B

    Other progress code are ignored. One symbol codes are displayed steady while
    two-symbol codes are displayed using blinking. Boot progress codes are
    displayed with decimal got unset (as opposed to 'display' command output).

  • This patch adds support for LED display on a4m072 board. Hardware is
    capable of displaying only one symbol at any time. We support displaying
    two symbols in software (via blinking).

  • This patch provides support for the A4M072 board with the following features:
    UART
    NOR flash
    FEC Ethernet
    External SRAM
    I2C EEPROM
    CompactFlash cards on IDE/ATA port
    USB Host
    PCI initialization

    The 7-segment LED indicator is not yet supported.
