[Qemu-devel] [PATCH 0/3] qemu-sparc updates

[Mark Cave-Ayland]

Here is the current contents of my qemu-sparc queue coming up to soft freeze.

Note the NVRAM changes are currently blocked on mutiple outstanding patchsets
summarised below:

1) isa: remove isa_mem_base variable
- Currently queued in Leon's target-mips tree

2) timer/m48t59: QOM'ify
- Should be picked up by Andreas via the QOM tree?
  http://lists.gnu.org/archive/html/qemu-devel/2015-02/msg00793.html

3) m48t59: add year offset and sysbus device
- Updated v3 posted by me this morning (no current owner)

[Qemu-devel] [PATCH 3/3] sun4u: switch m48t59 NVRAM to MMIO access

[Mark Cave-Ayland]

Real sun4u systems memory-map the NVRAM on the (ISA) ebus, so switch over to
MMIO from ioport access whilst setting the base year to 1968 as used by Sun
systems. This allows all SPARC64 OSs included in my tests to correctly detect
the NVRAM IC and read the hardware clock correctly upon boot.

Note that this also requires a corresponding OpenBIOS update to switch the
SPARC64 NVRAM accessors over from ioport to MMIO.
