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.

Those files were previously installed, but that's no longer the case
since we select in the menuconfig which version of the bootloader we
install.

Make the readme.txt for the raspberrypi board less misleading regarding the
kernel image file name.

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).

This is a default configuration for the RaspberryPi, tested and functional.
The kernel used is the one developped by the RaspberryPi foundation as
it's not fully supported currently in mainline kernel. The configuration
used for the kernel is the default bcmrpi.
