ee50eb8ad3 boards/raspberrypi0: new board
Add support for the rpi-0, which is basically a rpi (model A+) in a
smaller form-factor.

This one does not have an ethernet port, so we just remove it from the
configuration (or we could use the existing rasbperrypi_defconfig and
suffer from a longer boot time because of the waiting for eth0).

b159b15d07 configs: add Raspberry Pi 3 defconfig
So far identical to the rpi2 one except for the dts file as the SW runs in
32bit mode.

babf1190b3 raspberrypi, raspberrypi2: document the two consoles (UART+HDMI)
The defconfigs for the Raspberry Pi boards start a console on HDMI in
addition to the classic one on UART. Document this feature in the
readme.

20878a1017 raspberrypi, raspberrypi2: add a serial console
The current Buildroot defconfigs for Raspberry Pi and Raspberry Pi 2
instantiate a console on tty1, which appears on HDMI. Add a console on
the serial port (ttyAMA0) to be more consistent with other defconfigs
and provide a better out-of-the-box experience to users used to have a
serial console from Buildroot defconfigs.

This requires three changes:
 1. have two 'console=' entries in the kernel command line: tty1,
    then ttyAMA0;
 2. change BR2_TARGET_GENERIC_GETTY_PORT to "console", so it starts
    a getty on the last console= passed to the kernel, ttyAMA0;
 3. add a new getty on tty1 to the generated inittab.

Step 2 is actually obtained by removing BR2_TARGET_GENERIC_GETTY_PORT
entirely from the defconfigs, since "console" is the default value.

Step 3 requires a post-build script since the Buildroot makefiles can
configure only one console.

Note: instead of simply adding a new getty on ttyAMA0 (which would
work) this patch actually changes BR2_TARGET_GENERIC_GETTY_PORT to
instantiate a console on UART, then adds back tty1 via
post-build.sh. This is done only to avoid the "GENERIC_SERIAL" comment
where we instantiate an HDMI console, then instantiate a really-serial
console on another line.

The result is these two inittab lines:

  console::respawn:/sbin/getty -L  console 0 vt100 # GENERIC_SERIAL
  tty1::respawn:/sbin/getty -L  tty1 0 vt100 # HDMI console

8dd797a054 configs/raspberrypi*: update them to use genimage
Update the raspberrypi and raspberrypi2 configs to use genimage directly
to build the image.
Update the documentation to reflect this, and drop the volatile rootfs
option since it doesn't make much sense and it's not easily integrated
with the genimage configurations.

d8649ca874 configs/raspberrypi: update the DT-enabled config
Update to the latest stable kernel version; build an in-tree DTB; use
a in-tree defconfig; enable C++ (to match what we have in the non-DT
variant); do not install DTB overlays (this minimalist config does not
make use of them).

Generate the DTBs for both the "original" variant (A and B) and the
"Plus" variant (A+ and B+).

Drop our custom linux defconfig file now we use an in-tree one.

The RPi-2 has its own DTB, so document it in the list of generated

Also, not all DTBs need to be present on the boot partition, so add a
comment that identifies which should be copied for each model.

  - create a symlink raspberrypi2 -> raspberrypi

23da43ae12 configs: add a DT-enabled Raspberry Pi defconfig
This is an example of a Device-Tree-enabled Raspberry Pi defconfig.

We have to use a 3.18-based kernel for that, but there are a few
limitations:

  - we can not use the minimalist RPi defconfig bundled with the kernel,
    namely bcmrpi_quick_defconfig, because it is not DT-enabled, and
    sets CONFIG_ARM_PATCH_PHYS_VIRT to 'n', which prompts a value for
    CONFIG_PHYS_OFFSET, as it as no default for the bcm familly;

  - most importantly, the rpi-3.18.y branch is constantly rebased, so
    there is no guarantee that the sha1 I use today will still be usable
    in the long term. Using the name of hte branch is not better either.

So, we bundle our own DT-enabled linux defconfig that is based on
bcmrpi_quick_defconfig, with just CONFIG_ARM_PATCH_PHYS_VIRT set and the
Device TRee enabled.

094d8ec896 configs: rename rpi_defconfig for consistency
We name all of our boards and defconfig files based on the boards
fullname, not a nickname or a shortname.

'rpi' is short for Raspberry Pi, so name all our Raspberry Pi ressource
with 'raspberrypi' instead of 'rpi'.

This should also help Buildroot-newcomers to recognise Raspberry Pi
related files (defconfig and board doc).
