[Qemu-devel] [PATCHv2 0/2] m48t59: add year offset and sysbus device

[Mark Cave-Ayland]

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

Patch 1 introduces a new year_offset property which is the offset between the
year value stored in hardware and the actual year. In particular, Sun hardware
has a 68 year offset 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.

v2:
Rebase upon master plus Hervé's isa_mem_base and m48t59 QOM patchsets
Remove addition of mem_base parameter to m48t59_init_isa()
