[Qemu-devel] [PATCH 0/2] sparc64: Fix NVRAM access mode

[Artyom Tarasenko <atar4qemu@gmail.com>]

The sun4u machines use a slightly different modification of the ISA Mostek chip.
It has MMIO, 1968 as a base year and no IRQ line. Since it matches our m48t08,
make keep PIO behavior for the 59 model and use MMIO for the 8 model.

This series fixes recognising Mostek RTC in the Linux/sparc64 guest.

Artyom Tarasenko (2):
  m48t59: use mmio for the m48t08 model of the m48t59_isa card
  sparc64: Use the correct type of the Mostek NVRAM chip
