2013-01-16tmp105: Fix I2C protocol bugAndreas Färber
An early length postincrement in the TMP105's I2C TX path led to transfers of more than one byte to place the second byte in the third byte's place within the buffer and the third byte to get discarded. Fix this by explictly incrementing the length after the checks but before the callback is called, which again checks the length. Adjust the Coding Style while at it.

Introduce the QOM realizefn suggested by Anthony. Detailed documentation is supplied in the qdev header.

2013-01-15pseries: set no default boot orderAvik Sil
This patch removes the default boot order for pseries machine. This allows the machine to handle a NULL boot order in case no -boot option is provided. Thus it helps SLOF firmware to verify if boot order is specified in command line or not. If no boot order is provided SLOF tries to boot from the device set in the nvram.

2013-01-15Make default boot order machine specificAvik Sil
This patch makes default boot order machine specific instead of set globally. The default boot order can be set per machine in QEMUMachine boot_order. This also allows a machine to receive a NULL boot order when -boot isn't used and take an appropriate action accordingly. This helps machine boots from the devices as set in guest's non-volatile memory location in case no boot order is provided by the user.

2013-01-15hw/dma.c: Fix conversion of ioport_register* to MemoryRegionJulien Grall
The commit 582299336879504353e60c7937fbc70fea93f3da introduced a 1-shift for some offset in DMA emulation. Before the previous commit, which converted ioport_register_* to MemoryRegion, the DMA controller registered 8 ioports with the following formula: base + ((8 + i) << d->shift) where 0 <= i < 8 When an IO occured within a Memory Region, DMA callback receives an offset relative to the start address. Here the start address is: base + (8 << d->shift). The offset should be: (i << d->shift). After the shift is reverted, the offsets are 0..7 not 1..8. Fixes LP#1089996.
