4342557fad arm/mach-bcm283x/mbox: Flush and invalidate dcache when using fw mailbox
When using dcache the setup data for the mailbox must be actually written
into memory before calling into firmware. Thus flush and invalidate the
memory.

122426d46e ARM: bcm2835: use phys_to_bus() for mbox
When we communicate with the VideoCore to perform property mailbox
transactions, that is a DMA operation as far as the property buffer
is concerned. Use phys_to_bus() on that buffer.

ddf6bd4876 ARM: bcm283x: merge BCM2835/BCM2836 directories into mach-bcm283x
BCM2835 (used on Raspberry Pi) and BCM2836 (used on Raspberry Pi 2)
are similar enough.  One of the biggest differences is the ARM
processor.  It is reasonable to collect the source files into a
single place, arch/arm/mach-bcm283x/.
