  • beab697ab   serial driver PMC MSP71xx ... Browse Code »

    Serial driver patch for the PMC-Sierra MSP71xx devices.

    There are three different fixes:

    1 Fix for DesignWare APB THRE errata: In brief, this is a non-standard
    16550 in that the THRE interrupt will not re-assert itself simply by
    disabling and re-enabling the THRI bit in the IER, it is only re-enabled
    if a character is actually sent out.

    It appears that the "8250-uart-backup-timer.patch" in the "mm" tree
    also fixes it so we have dropped our initial workaround. This patch now
    needs to be applied on top of that "mm" patch.

    2 Fix for Busy Detect on LCR write: The DesignWare APB UART has a feature
    which causes a new Busy Detect interrupt to be generated if it's busy
    when the LCR is written. This fix saves the value of the LCR and
    rewrites it after clearing the interrupt.

    3 Workaround for interrupt/data concurrency issue: The SoC needs to
    ensure that writes that can cause interrupts to be cleared reach the UART
    before returning from the ISR. This fix reads a non-destructive register
    on the UART so the read transaction completion ensures the previously
    queued write transaction has also completed.

  • 97dcb82de   [MIPS] Define MIPS_CPU_IRQ_BASE in generic header ... Browse Code »

    The irq_base for {mips,rm7k,rm9k}_cpu_irq_init() are constant on all
    platforms and are same value on most platforms (0 or 16, depends on
    CONFIG_I8259). Define them in asm-mips/mach-generic/irq.h and make
    them customizable. This will save a few cycle on each CPU interrupt.

    A good side effect is removing some dependencies to MALTA in generic
    SMTC code.

    Although MIPS_CPU_IRQ_BASE is customizable, this patch changes irq
    mappings on DDB5477, EMMA2RH and MIPS_SIM, since really customizing
    them might cause some header dependency problem and there seems no
    good reason to customize it. So currently only VR41XX is using custom
    MIPS_CPU_IRQ_BASE value, which is 0 regardless of CONFIG_I8259.

    Testing this patch on those platforms is greatly appreciated. Thank
    you.

  • 16b7b2ac0   [MIPS] Fixup migration to GENERIC_TIME ... Browse Code »

    Since we already moved to GENERIC_TIME, we should implement alternatives
    of old do_gettimeoffset routines to get sub-jiffies resolution from
    gettimeofday(). This patch includes:

    * MIPS clocksource support (based on works by Manish Lachwani).
    * remove unused gettimeoffset routines and related codes.
    * remove unised 64bit do_div64_32().
    * simplify mips_hpt_init. (no argument needed, __init tag)
    * simplify c0_hpt_timer_init. (no need to write to c0_count)
    * remove some hpt_init routines.
    * mips_hpt_mask variable to specify bitmask of hpt value.
    * convert jmr3927_do_gettimeoffset to jmr3927_hpt_read.
    * convert ip27_do_gettimeoffset to ip27_hpt_read.
    * convert bcm1480_do_gettimeoffset to bcm1480_hpt_read.
    * simplify sb1250 hpt functions. (no need to subtract and shift)

  • 2925aba42   [MIPS] Cleanup memory managment initialization. ... Browse Code »

    Historically plat_mem_setup did the entire platform initialization. This
    was rather impractical because it meant plat_mem_setup had to get away
    without any kind of memory allocator. To keep old code from breaking
    plat_setup was just renamed to plat_setup and a second platform
    initialization hook for anything else was introduced.

  • e4ac58afd   [MIPS] Rewrite all the assembler interrupt handlers to C. ... Browse Code »

    Saves like 1,600 lines of code, is way easier to debug, compilers
    frequently do a better job than the cut and paste type of handlers many
    boards had. And finally having all the stuff done in a single place
    also means alot of bug potencial for the MT ASE is gone.

    The only surviving handler in assembler is the DECstation one; I hope
    Maciej will rewrite it.

  • 9b6695a8a   [MIPS] SMP: Fix initialization order bug. ... Browse Code »

    A recent change requires cpu_possible_map to be initialized before
    smp_sched_init() but most MIPS platforms were initializing their
    processors in the prom_prepare_cpus callback of smp_prepare_cpus. The
    simple fix of calling prom_prepare_cpus from one of the earlier SMP
    initialization hooks doesn't work well either since IPIs may require
    init_IRQ() to have completed, so bit the bullet and split
    prom_prepare_cpus into two initialization functions, plat_smp_setup
    which is called early from setup_arch and plat_prepare_cpus called where
    prom_prepare_cpus used to be called.
