      MIPS: Ingenic XBurst Jz4740 processor support · 80421fcc
      Xiangfu Liu authored
      Jz4740 is a multimedia application processor targeting for mobile
      devices like e-Dictionary, eBook, portable media player (PMP) and
      GPS navigator.  Jz4740 is powered by Ingenic 360 MHz XBurst CPU core
      (JzRISC), in which RISC/SIMD/DSP hybrid instruction set architecture
      provides high integration, high performance and low power consumption.
      
      JzRISC incorporated in Jz4740 is the advanced and power-efficient
      32-bit RISC core, compatible with MIPS32, with 16K I-Cache and 16K
      D-Cache, and can operate at speeds up to 400 MHz.
      
      On-chip modules such as LCD controller, embedded audio codec, multi-
      channel SAR-ADC, AC97/I2S controller and camera I/F offer a rich
      suite of peripherals for multimedia application.  NAND controller
      (SLC/MLC), USB (host 1.1 and device 2.0), UART, I2C, SPI, etc. are
      also available.

      This patch introduces XBurst CPU support in U-Boot.  It's compatible
      with MIPS32, but requires a bit different cache maintenance, timer
      routines, and boot mechanism using USB boot tool, so XBurst support
      can go into a separate new home, cpu/xburst/.

      MIPS: Move timer code to arch/mips/cpu/$(CPU)/ · 68cebb80
      Shinya Kuribayashi authored
      
      
      Current timer routines (arch/mips/lib/timer.c) are implemented assuming
      that MIPS32 coprocessor (CP0) resources, Counter and Compare registers
      in this case, are available.  But this doesn't always work.
      
      We need to make sure that all MIPS-based systems don't necessarily use
      CP0 counter/compare registers as time keeping resources.  And some MIPS
      variant processors might come with different hardware specs with genuine
      MIPS32 CP0 registers.
      
      With this change, each $(CPU)/ directory can have its own timer code.

      Switch from archive libraries to partial linking · 6d8962e8
      Sebastien Carlier authored
      
      
      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.

      Add support for a saving build objects in a separate directory. · f9328639
      Marian Balakowicz authored
      Modifications are based on the linux kernel approach and
      support two use cases:
      
        1) Add O= to the make command line
        'make O=/tmp/build all'
      
        2) Set environement variable BUILD_DIR to point to the desired location
        'export BUILD_DIR=/tmp/build'
        'make'
      
      The second approach can also be used with a MAKEALL script
      'export BUILD_DIR=/tmp/build'
      './MAKEALL'
      
      Command line 'O=' setting overrides BUILD_DIR environent variable.
      
      When none of the above methods is used the local build is performed and
      the object files are placed in the source directory.
