[PATCH 0/4] arm: Add PSTATE field registers CurrentEL, NZCV, DAIF, SPSel to gdbstub

[Manos Pitsidianakis]

Expose PSTATE field registers to gdbstub:

  (gdb) info registers
  <- snip ->
  sp             0x0                 0x0
  pc             0x40000000          0x40000000
  cpsr           0x400003c5          [ SP EL=1 F I A D BTYPE=0 Z ]
  fpsr           0x0                 0
  fpcr           0x0                 0
  vg             0x2                 2
  pauth_dmask    0xffff000000000000  -281474976710656
  pauth_cmask    0xffff000000000000  -281474976710656
  pauth_dmask_high 0xffff000000000000 -281474976710656
  pauth_cmask_high 0xffff000000000000 -281474976710656
  CurrentEL      0x4                 [ EL=1 ]
  NZCV           0x40000000          [ Z ]
  DAIF           0x3c0               [ F I A D ]
  SPSel          0x1                 [ SP ]
  <-snip->

This also would allow plugins to access those registers.
