* arm/mach-bcm283x/mbox: Flush and invalidate dcache when using fw mailboxAlexander Stein2015-08-121-0/+9
| | | | | | | | | | 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.

* ARM: bcm2835: use phys_to_bus() for mboxStephen Warren2015-04-141-2/+3
| | | | | | | | 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. Signed-off-by: Stephen Warren <swarren@wwwdotorg.org>
* ARM: bcm283x: merge BCM2835/BCM2836 directories into mach-bcm283xMasahiro Yamada2015-03-281-0/+153
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/.
