* bcm283x: mbox: align to cachesizeAlexander Aring2016-01-041-1/+3
| | | | | | | | | | | | This patch change the align of mbox stack resource to 32. The reason is that I had some experience with bcm2836 and the mbox implementation, after setting the align to 64(on bcm2836) the issues was gone. I found these values inside the u-boot implementation, they use 32 (bcm2835) and 64 (bcm2836).

* bcm2835: introduce mach-bcm283xAlexander Aring2016-01-049-0/+936
This patch changes the most part of mach-bcm2835 to mach-bcm283x. This prepares to add RPi2 support which is a bcm2836. This patch changes the Kconfig entry namens to BCM283X for drivers only. These drivers should working the same in bcm2836. While updating defconfig I added LED support/trigger option.
