Lubomir Rintel bf7389c49d ARM: bcm2835: enable USB_DWC2_HOST in defconfig
It broke when host was moved into a separate module, in 47a1685 ("usb:
dwc2/s3c-hsotg: move s3c-hsotg into dwc2 directory"),

Markus Mayer d30fe62721 ARM: bcm2835: Move to mach-bcm directory
Move the bcm2835 board file into the mach-bcm directory. This allows us
to get rid of the mach-bcm2835 directory with the associated Kconfig
and Makefile.

Stephen Warren 5cea04bab5 ARM: bcm2835: bcm2835_defconfig updates
Rebuild bcm2835_defconfig using "make bcm2835_defconfig;
make savedefconfig", and add the following features:

* Enable the DWC2 USB controller present in the BCM2835 SoC.
* Enable drivers for various USB-hosted devices, which make the
  controller useful.

Stephen Warren c321e71644 ARM: bcm2835: defconfig updates
Enable CONFIG_LEDS_GPIO and all options required to enable it, or make
the option useful.

Enable the simple framebuffer driver, fbconsole, and VT support.

This patch also regenerated bcm2835_defconfig, which removes two HW_RANDOM
entries, since they're enabled by default.

Linus Torvalds 99c6bcf46d ARM: arm-soc multiplatform updates for 3.10
More multiplatform enablement for ARM platforms. The ones converted in
 this branch are:
 - bcm2835
 - cns3xxx
 - sirf
 - nomadik
 - msx
 - spear
 - tegra
 - ux500
 
 We're getting close to having most of them converted!
 
 One of the larger platforms remaining is Samsung Exynos, and there are
 a bunch of supporting patches in this merge window for it. There was a
 patch in this branch to a early version of multiplatform conversion,
 but it ended up being reverted due to need of more bake time. The
 revert commit is part of the branch since it would have required
 rebasing multiple dependent branches and they were stable by then.

Stephen Warren f1ac922dec ARM: bcm2835: convert to multi-platform
This allows BCM2835 be included in a kernel build that supports multiple
SoCs at once, which is useful for distro kernels.

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.

Stephen Warren d1dc7c6c6a 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.

Thomas Petazzoni a6380c13c1 ARM: bcm2835: enable procfs and sysfs in defconfig
For some reason, support for proc and sysfs is currently disabled in
the bcm2835_defconfig, even though those filesystems are quite
essential even for very basic Linux userspace. As most defconfig have
them enabled by default, enable them as well in bcm2835_defconfig.

Simon Arlott ec9653b847 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.
