Subject: [PATCH 0/6] Use build registers for getting numbers of interrupts

A summary:

  * Use build registers for getting numbers of interrupts both for
    core interrupt controller and for IDU interrupt controller.
  * Set a default priority for all core interrupt to prevent
    unexpected switching of banks of registers.
  * Remove option for setting number of interrupts since it does
    not affect a number of interrupts in IRQ domains and breaks
    portability since it is impossible to change size of table of
    interrupts after linkage.

Yuriy Kolerov (6):
  ARCv2: IRQ: Move structures for core intc to the header
  ARCv2: MCIP: Add structure for build register of IDU
  ARCv2: IRQ: Add macro for the first external interrupt number
  ARCv2: IRQ: Remove option for setting number of interrupts
  ARCv2: IRQ: Use build registers for getting numbers of interrupts
  ARCv2: IRQ: Set a default priority for all core interrupts
