vcdbg is a tool to help debug the communication with the GPU.
It comes as a binary-only, and in two flavours: one for the hard
floating point ABI, one for the software floating point ABI.
Unfortunately, we have no source code for that tool, only a binary that
was dynamically linked with glibc and libraries from rpi-userland.
So, just install that executable, and let's hope there is no symbol
issue at runtime.
Note: vcdbg needs glibc, threads and !static. Since glibc already
implies threads and !static, we only need to depend on glibc.

Remove low-level settings from config.txt like arm_freq and sdram_freq.
The defaults should be good for most and differ by Pi model.
E.g. the Pi 2 runs at 900 Mhz by default, setting arm_freq=700
like we had previously would underclock it.
Add short description in comments to options.
Mention initramfs option.

The rpi-firmware we currently package has a fiscious bug, that happens
in corner cases while reading config.txt (mostly seen on RPi-2, but may
also occur on RPi-1).
Both the DT-aware and DT-unaware branches are affected.
Bump to the latest rpi-firmware to fix that.

Add an option to install all the DTBs:
- standard DTBs for standalon A/B and A+/B+ models;
- overlay DTBs for the 'hats' addon boards.
Install the DTBs as per the traditional layout expected by all RPi
users, that is:
- base DTBs alongside the other boot files;
- overlay DTBs in a sub-directory.
This requires the user provide a specially configured Linux defconfig
file, as the default ones do not enable USE_OF.
[Thomas: adjust comment explaining why we use a different version when
installing the DTBs is selected.]

The Raspberry Pi can boot a kernel with device tree support. But at the
same time, the RPi folks wante to keep the old-fashioned, ATAG-based way
of booting (don't ask...).
So, the bootloader needs to know whether the kernel it is loading has DT
support or not. For that, it looks at the end of the kernel image for a
magic footer. If found, it loads a device tree and sets the registers
appropriately so that the kernel finds the DTB. If not found, it loads
the kernel with the traditional ATAGS.
Where it becomes a bit tricky, is that the DTB is different for models
A/B and A+/B+ (that is A and B use the same DTB, while the A+ and B+ use
a second DTB). The bootloader is capable to load the correct DTB from a
specially named file. That is:
- on A/B, it loads bcm2708-rpi-b.dtb
- on A+/B+, it loads bcm2708-rpi-b-plus.dtb
If the DTB is differently named, the bootloader won't find it, will not
load any DTB at all, and revert to booting with ATAGS.
It is possible to specify what DTB to load, by adding an new config
option 'device_tree=file.dtb' in config.txt, but then the firmware on
the SDcard is no longer bootable on both the original models and the
Plus models.
So, add a script that appends the appropriate footer to the kernel
image. The script is vampirised from the RPi's tools repository, but a
new package is *not* added just for that script: the whole repository is
300+ MiB, and a checkout is 600+ MiB; it is not pertinent to add this as
a new package for a script that weights a few KiB...
Install that script as a host utility, too.
