[3/5] hw/arm/bcm Fix crash with device_add bcm on unsupported machines - Patchwork
Now that the interrupt has fired, disable it. Data Structure Mailbox merely enables the processors to transmit buffer pointers. The structure of this buffer contents would depend on the channel.

Thus a peripheral advertised in the manual at bus address 0x7Ennnnnn is available at physical address 0x20nnnnnn. This is only availble with recent versions of the kernel on RPI 2.
You should also ensure you are using the latest version of Linux.
[PATCH 05/10] arm/raspberrypi: more definitions of BCM core local peripherals.
Without bcm 2836 arm peripherals tree support enabled and the presence of this file, it will not work on RPI2. To enable device tree support: There's also an exception for "VC4 big island" whose main header is not included, but I can't really find much about it, although this remark is an interesting one.
So it makes sense for drivers to be referring to the especially if they were developed by broadcom. I'm not sure bcm 2836 arm peripherals to make of the rpi2 reporting bcm I've also modified delayMicroseconds to use nanosleep for long waits, and a busy wait on a high resolution timer for the rest.
This is because I've found that calling nanosleep takes at least us. You need to link using '-lrt' using this version.

Requested by Sebastian Loncar. No need to link with -lrt now.
