bcm2835_dma: add emulation of Raspberry Pi DMA controller
...
At present, all DMA transfers complete inline (so a looping descriptor
queue will lock up the device). We also do not model pause/abort,
arbitrarion/priority, or debug features.

bcm2835_property: implement framebuffer control/configuration properties
...
The property channel driver now interfaces with the framebuffer device
to query and set framebuffer parameters. As a result of this, the "get
ARM RAM size" query now correctly returns the video RAM base address
(not total RAM size), and the ram-size property is no longer relevant
here.

bcm2835_fb: add framebuffer device for Raspberry Pi
...
The framebuffer occupies the upper portion of memory (64MiB by
default), but it can only be controlled/configured via a system
mailbox or property channel (to be added by a subsequent patch).

bcm2835_aux: add emulation of BCM2835 AUX (aka UART1) block
...
At present only the core UART functions (data path for tx/rx) are
implemented, which is enough for UEFI to boot. The following
features/registers are unimplemented:
* Line/modem control
* Scratch register
* Extra control
* Baudrate
* SPI interfaces

bcm2835_property: implement "get board revision" query
...
Return a valid value from the BCM2835 property mailbox query "get board
revision". This query is used by U-Boot. Implementing it fixes the first
obvious difference between qemu and real HW.
The value returned is currently hard-coded to match the RPi2 I own. Other
values are legal, e.g. different board manufacturer field values are
likely to exist in the wild.
