[Qemu-devel] [PATCHv4 0/2] m48t59: add year offset and sysbus device

This patchset lays the groundwork for switching sun4u over from ioport NVRAM
access to MMIO NVRAM access.

Patch 1 introduces a new base-year property which represents the base year of
the zero hardware year value. In particular, Sun hardware has a base year of 
1968 used to extend the date range of the IC. While the kernel sources I have
viewed contain this offset within a #ifdef CONFIG_SPARC block, I've updated all 
the callers so that no change in behaviour will be seen across all platforms. 
PPC users may wish to alter the callers to change this behaviour as required.

Patch 2 adds a new m48t59 sysbus device in preparation for use with sun4u in a
subsequent patch.

Rebase upon master
Rename base_year property to base-year as suggested by Hervé
Fix mistake with ppc405 board base year

Change year_offset qdev parameter to base_year to match mc146818rtc as
suggested by Hervé

Rebase upon master plus Hervé's isa_mem_base and m48t59 QOM patchsets
Remove addition of mem_base parameter to m48t59_init_isa()

Mark Cave-Ayland (2):
  m48t59: introduce new base-year qdev property
  m48t59: add m48t59 sysbus device
