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.

ARM: bcm2835: defconfig updates Now that we have an SDHCI driver, enable the block layer, and common filesystems; MSDOS/VFAT for the SoC-required firmware partition, ext2/3/4 for a root partition. Add tmpfs, NFS, file locking, file notify, networking, and NLS to support distro expectations. Enable GPIO_SYSFS to allow GPIO twiddling from user-space; likely a common activity on this hardware. Enable I2C. Remove bogus CONFIG_DEFAULT_MMAP_MIN_ADDR so that applications running as non-root actually work; without this, execve() immediately triggers SIGKILL. This setting was sourced from some downstream defconfig early during upstream Raspberry Pi support development. Other non-semantic diffs due to rebuilding defconfig using the latest Kconfig defaults etc. Signed-off-by: Stephen Warren <swarren@wwwdotorg.org>

This change: * Moves bcm2835's debug-macro.S into ARM's include/debug/, and hooks it into the relevant menu. * Moves bcm2835's Kconfig into its own directory, as seems typical for multi-platform conversions. * Removes bcm2835_soc.h, and moves the content to the files where it was used; just one usage per define. * Deletes some headers and Makefile.boot that aren't needed now that we support multi-platform.

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.

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.
