      metag: Add JTAG Debug Adapter (DA) support · ae85ac71
      James Hogan authored
      Add basic JTAG Debug Adapter (DA) support so that drivers which
      communicate with the DA can detect whether one is actually present
      (otherwise the target will halt indefinitely).
      
      This allows the metag_da TTY driver and imgdafs filesystem driver to be
      built, updates defconfigs, and sets up the metag_da console early if
      it's configured in.

      metag: Internal and external irqchips · 5698c50d
      James Hogan authored
      Meta core internal interrupts (from HWSTATMETA and friends) are vectored
      onto the TR1 core trigger for the current thread. This is demultiplexed
      in irq-metag.c to individual Linux IRQs for each internal interrupt.
      
      External SoC interrupts (from HWSTATEXT and friends) are vectored onto
      the TR2 core trigger for the current thread. This is demultiplexed in
      irq-metag-ext.c to individual Linux IRQs for each external SoC interrupt.
      The external irqchip has devicetree bindings for configuring the number
      of irq banks and the type of masking available.

      metag: Time keeping · a2c5d4ed
      James Hogan authored
      Add time keeping code for metag. Meta hardware threads have 2 timers.
      The background timer (TXTIMER) is used as a free-running time base, and
      the interrupt timer (TXTIMERI) is used for the timer interrupt. Both
      counters traditionally count at approximately 1MHz.
