2018-08-23i2c: pm_smbus: Add the ability to force block transfer enableCorey Minyard
The PIIX4 hardware has block transfer buffer always enabled in the hardware, but the i801 does not. Add a parameter to pm_smbus_init to force on the block transfer so the PIIX4 handler can enable this by default, as it was disabled by default before.

2018-08-23i2c: pm_smbus: Add block transfer capabilityCorey Minyard
There was no block transfer code in pm_smbus.c, and it is needed for some devices. So add it. This adds both byte-by-byte block transfers and buffered block transfers.

2013-04-08hw: move headers to include/Paolo Bonzini
Many of these should be cleaned up with proper qdev-/QOM-ification. Right now there are many catch-all headers in include/hw/ARCH depending on cpu.h, and this makes it necessary to compile these files per-target. However, fixing this does not belong in these patches.
