net/dp8393x and dma/rc4030 improvements

Hi,

This patchset improves dp8393x network card emulation to current QEMU standards, mostly decouples it from MIPS rc4030 chipset emulation, adds PROM and load/save functionalities, and fixes some bugs seen with NetBSD.
It also converts rc4030 to QOM, and does some cleanup.

Patchset has been tested on MIPS Jazz emulation and on (yet unpublished) m68k Quadra 800 emulation.

Changes v2->v3:
- patch 1: keep mips jazz compilation on 64 bit big endian
- patch 14: do not use a temporary variable
- patch "net/dp8393x: repair can_receive() method" removed

Changes v1->v2:
- added patches 1, 5-7, 14-16
- fixed memory region life cycle in rc4030 (patch 2)
- removed a loop around address_space_rw (patch 2)
- added RFC patch 17, which highlights a bug somewhere

Hervé Poussineau (16):
mips jazz: compile only in 64 bit
dma/rc4030: create custom DMA address space
dma/rc4030: use AddressSpace and address_space_rw in users dma/rc4030: do not use old_mmio accesses
dma/rc4030: document register at offset 0x210
dma/rc4030: use trace events instead of custom logging dma/rc4030: convert to QOM
net/dp8393x: always calculate proper checksums net/dp8393x: do not use old_mmio accesses
net/dp8393x: use dp8393x_ prefix for all functions net/dp8393x: QOM'ify
net/dp8393x: add PROM to store MAC address
net/dp8393x: add load/save support
net/dp8393x: correctly reset in_use field
net/dp8393x: fix hardware reset
[RFC] dma/rc4030: do multiple calls to address_space_rw when doing DMA
