[PULL 01/13] macio: don't reference serial_hd() directly within the device

[Mark Cave-Ayland]

Instead use qdev_prop_set_chr() to configure the ESCC serial chardevs at the
Mac Old World and New World machine level.

Also remove the now obsolete comment referring to the use of serial_hd() and
the setting of user_creatable to false accordingly.

[PULL 02/13] grackle: use qdev gpios for PCI IRQs

[Mark Cave-Ayland]

Currently an object link property is used to pass a reference to the Heathrow
PIC into the PCI host bridge so that grackle_init_irqs() can connect the PCI
IRQs to the PIC itself.

This can be simplified by defining the PCI IRQs as qdev gpios and then wiring
up the PCI IRQs to the PIC in the Old World machine init function.

[PULL 03/13] uninorth: use qdev gpios for PCI IRQs

[Mark Cave-Ayland]

Currently an object link property is used to pass a reference to the OpenPIC
into the PCI host bridge so that pci_unin_init_irqs() can connect the PCI
IRQs to the PIC itself.

This can be simplified by defining the PCI IRQs as qdev gpios and then wiring
up the PCI IRQs to the PIC in the New World machine init function.

[PULL 09/13] mac_oldworld: Allow loading binary ROM image

[Mark Cave-Ayland]

From: BALATON Zoltan via <qemu-devel@nongnu.org>

The beige G3 Power Macintosh has a 4MB firmware ROM. Fix the size of
the rom region and fall back to loading a binary image with -bios if
loading ELF image failed. This allows testing emulation with a ROM
image from real hardware as well as using an ELF OpenBIOS image.

[PULL 10/13] mac_newworld: Allow loading binary ROM image

[Mark Cave-Ayland]

From: BALATON Zoltan <balaton@eik.bme.hu>

Fall back to load binary ROM image if loading ELF fails. This also
moves PROM_BASE and PROM_SIZE defines to board as these are matching
the ROM size and address on this board and removes the now unused
PROM_ADDR and BIOS_SIZE defines from common mac.h.

[PULL 11/13] mac_oldworld: Drop a variable, use get_system_memory() directly

[Mark Cave-Ayland]

From: BALATON Zoltan <balaton@eik.bme.hu>

Half of the occurances already use get_system_memory() directly
instead of sysmem variable, convert the two other uses to
get_system_memory() too which seems to be more common and drop the
variable.

[PULL 12/13] mac_oldworld: Drop some variables

[Mark Cave-Ayland]

From: BALATON Zoltan <balaton@eik.bme.hu>

Values not used frequently enough may not worth putting in a local
variable, especially with names almost as long as the original value
because that does not improve readability, to the contrary it makes it
harder to see what value is used. Drop a few such variables.
