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: refresh defconfig files A lot of Kconfig options have changed over the years, and we tend to not do a blind 'make defconfig' to refresh the files, to ensure we catch options that should not have gone away. I used some a bit of scripting to only rework the bits where an option moved around in any of the defconfig files, without also dropping any of the other lines, to make it clearer which options we no longer have.

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: refresh defconfig files A lot of Kconfig options have changed over the years, and we tend to not do a blind 'make defconfig' to refresh the files, to ensure we catch options that should not have gone away. I used some a bit of scripting to only rework the bits where an option moved around in any of the defconfig files, without also dropping any of the other lines, to make it clearer which options we no longer have.

ARM: refresh defconfig files A lot of Kconfig options have changed over the years, and we tend to not do a blind 'make defconfig' to refresh the files, to ensure we catch options that should not have gone away. I used some a bit of scripting to only rework the bits where an option moved around in any of the defconfig files, without also dropping any of the other lines, to make it clearer which options we no longer have.
