Hello.
This patch series is added Renesas RX target emulation.

Fix is bellow.
- Reorder patches.
- Rewrite renesas_cmt.
  Convert to RCMTChannelStatus
- Use CPUClass::tlb_fill
- Use tcg_gen_abs_i32
- Fix racw instructions.
- Cleanup for review comment.
  target/rx/helper.c - fix spelling.
  hw/intc/rx_icu.h - cleanup constant definition.
  hw/registerfields.h - fix macro definion order.

My git repository is bellow.
git://git.pf.osdn.net/gitroot/y/ys/ysato/qemu.git tags/rx-20190522

$ git backport-diff -u rx14 -r origin/master..rx15
Key:
[----] : patches are identical
[####] : number of functional differences between upstream/downstream patch

The flags [FC] indicate (F)unctional and (C)ontextual differences,
respectively

- you removed rx_abs(),
- one change in trans_RACW()
- fixed typos (Richard fixe them)
- LOT of changes in the timer device, you added RCMTChannelState()

Hmm you did reset some of the R-b T-b tags.


I guess Richard already prepared a pull request for your v14.

At this point I'd prefer the v14 get merged, and the v15 changes amended
as new commits. This would ease review/testing.

Maybe Richard can still amend the 'trans_RACW' one-line fix on his pullreq.

Richard what's your take on this?

Regards,

Phil.
