From ec9653b8476bf526dde7bdefbc2be6b7aaa34db7 Mon Sep 17 00:00:00 2001 From: Simon Arlott Date: Sat, 26 May 2012 01:04:43 -0600 Subject: ARM: add infra-structure for BCM2835 and Raspberry Pi The BCM2835 is an ARM SoC from Broadcom. This patch adds very basic support for this SoC. http://www.broadcom.com/products/BCM2835 http://www.raspberrypi.org/wp-content/uploads/2012/02/BCM2835-ARM-Peripherals.pdf Note that the documentation in the latter .pdf assumes the MMU setup that's used on the "VideoCore" companion processor, and does not document physical peripheral addresses. Subtract 0x5e000000 to obtain the physical addresses. This is accounted for by the ranges property in the /soc node in the device tree. The BCM2835 SoC is used in the Raspberry Pi. This patch also adds a minimal device tree for this board; enough to see some very early kernel boot messages through earlyprintk. However, this patch does not yet provide a useful booting system. http://www.raspberrypi.org/. This patch was extracted from git://github.com/lp0/linux.git branch rpi-split from 3-4 months ago, and significantly stripped down and modified since.
