1a5a557088 hw/misc/grlib_ahb_apb_pnp: Fix AHB PnP 8-bit accesses
The Plug & Play region of the AHB/APB bridge can be accessed
by various word size, however the implementation is clearly
restricted to 32-bit:

  static uint64_t grlib_ahb_pnp_read(void *opaque, hwaddr offset, unsigned size)
  {
      AHBPnp *ahb_pnp = GRLIB_AHB_PNP(opaque);

      return ahb_pnp->regs[offset >> 2];
  }

Similarly to commit 0fbe394a64 with the APB PnP registers,
set the MemoryRegionOps::impl min/max fields to 32-bit, so
memory.c::access_with_adjusted_size() can adjust when the
access is not 32-bit.

95722b2784 stubs: Restrict ui/win32-kbd-hook to system-mode
In Makefile.objs, the ui/ directory is restricted to system-mode:

 43 ifeq ($(CONFIG_SOFTMMU),y)
 ...
 65 common-obj-y += ui/
 66 common-obj-m += ui/
 ...
 82 endif # CONFIG_SOFTMMU

Restrict the ui/ stub added in commit 2df9f5718d to only build
it for system-mode emulation.

37914f603f tests/Makefile: Restrict some softmmu-only tests
In the next commit we are going to remove some objects from the
util-obj-y variable (objects which are not used by user-mode,
when configured with --disable-system).
Then some system-mode tests are going to fail, due to the missing
objects:

Instead, restrict these tests to system-mode, by using the

257a7e212d linux-user/mmap.c: fix integer underflow in target_mremap
Fixes: https://bugs.launchpad.net/bugs/1876373

This code path in mmap occurs when a page size is decreased with mremap.  When a section of pages is shrunk, qemu calls mmap_reserve on the pages that were released.  However, it has the diff operation reversed, subtracting the larger old_size from the smaller new_size.  Instead, it should be subtracting the smaller new_size from the larger old_size.  You can also see in the previous line of the change that this mmap_reserve call only occurs when old_size > new_size.

2c35a39eda target/arm: Convert Neon one-register-and-immediate insns to decodetree
Convert the insns in the one-register-and-immediate group to decodetree.

In the new decode, our asimd_imm_const() function returns a 64-bit value
rather than a 32-bit one, which means we don't need to treat cmode=14 op=1
as a special case in the decoder (it is the only encoding where the two
halves of the 64-bit value are different).

7ad3d51ebb usb: add short-packet handling to usb-storage driver
The dwc-hsotg (dwc2) USB host depends on a short packet to
indicate the end of an IN transfer. The usb-storage driver
currently doesn't provide this, so fix it.

I have tested this change rather extensively using a PC
emulation with xhci, ehci, and uhci controllers, and have
not observed any regressions.

153ef1662c dwc-hsotg (dwc2) USB host controller emulation
Add the dwc-hsotg (dwc2) USB host controller emulation code.
Based on hw/usb/hcd-ehci.c and hw/usb/hcd-ohci.c.

Note that to use this with the dwc-otg driver in the Raspbian
kernel, you must pass the option "dwc_otg.fiq_fsm_enable=0" on
the kernel command line.

Emulation of slave mode and of descriptor-DMA mode has not been
implemented yet. These modes are seldom used.

I have used some on-line sources of information while developing
this emulation, including:

http://www.capital-micro.com/PDF/CME-M7_Family_User_Guide_EN.pdf
which has a pretty complete description of the controller starting
on page 370.

https://sourceforge.net/p/wive-ng/wive-ng-mt/ci/master/tree/docs/DataSheets/RT3050_5x_V2.0_081408_0902.pdf
which has a description of the controller registers starting on
page 130.

Thanks to Felippe Mathieu-Daude for providing a cleaner method
of implementing the memory regions for the controller registers.
