   4 Subject: [PATCH] irqchip/qeic: merge qeic init code from platforms to a common
   5  function
   6
   7 The codes of qe_ic init from a variety of platforms are redundant,
   8 merge them to a common function and put it to irqchip/irq-qeic.c
   9
  10 For non-p1021_mds mpc85xx_mds boards, use "qe_ic_init(np, 0,
  11 qe_ic_cascade_low_mpic, qe_ic_cascade_high_mpic);" instead of
  12 "qe_ic_init(np, 0, qe_ic_cascade_muxed_mpic, NULL);".
  13
  14 qe_ic_cascade_muxed_mpic was used for boards has the same interrupt
  15 number for low interrupt and high interrupt, qe_ic_init has checked
  16 if "low interrupt == high interrupt"
