[Qemu-devel] [PATCH v2 0/8] ppc: cpu_model handling cleanups

[Igor Mammedov]

Changelog since v1:
  - normalize all cpu model names to lower-case
  - check that all cpu model string is consumed
    before going to PVR lookup path
  - add a new optional patch to remove unused junk
     '[PATCH v2 8/8] ppc: remove non implemented cpu models'
  - pull in dependency patch from
      https://lists.gnu.org/archive/html/qemu-devel/2017-08/msg03364.html
      'ppc: replace cpu_ppc_init() with cpu_generic_init()'
    so this series won't depend unnecessarily on another series

While removing cpu_init() tree-wide, I've stumbled uppon
PPC way of parsing cpu_model which looked way too complex
compared to other targets.

So here goes cleanups that instead of current inconsistent
way of dealing with cpu models
 - mix of case-(in)sensetive lookups and cpu model names
 - aliases pointing to another aliases
normalize cpu model names to upper-case and make aliases
point to cpu moldel names. These changes allow to simplify
cpu model handling quite a bit and make it look/behave
a bit more in line with other targets.
 
Patches are not must have for cpu_init() removal but make
it a little bit easier without need to deal with way of
conversion of cpu model to cpu type, so pls consider
merging it early once 2.11 merge window is open if
patches make any sense.

Igor Mammedov (8):
  ppc: replace cpu_ppc_init() with cpu_generic_init()
  ppc: use macros to make cpu type name from string literal
  ppc: make cpu_model translation to type consistent

  ppc: replace inter-function cyclic dependency/recurssion with 2 simple
    lookups
