Paolo Pisati April 5, 2016, 2:09 p.m. UTC 
This pull contains a rebase of the Xenial raspi2 branch on Ubuntu-4.4.0-17.33,
plus an update of the Broadcom/Raspberry BSP.

Among the usual slew of fixes and small improvements, the big feature of this
BSP update is a backport of the DT-Overlay configfs interface from upstream.

In other words, it is finally possible to load (and remove) a dt overlay at
runtime using configfs:

# mkdir /config
# mount -t configfs none /config
# mkdir /config/device-tree/overlays/$DTBO-NAME
# cat $DTBO-NAME.dtbo > /config/device-tree/overlays/$DTBO-NAME/dtbo

And later to remove it:

# rmdir /config/device-tree/overlays/$DTBO-NAME

This feature is intended for developer only, and sometimes loading a dtbo is a one
way journey, still it's a nice feature to have.

A side effect of this update (completely unrelated to the inclusion of
DT-Overlay configfs) is that the resulting dtb for the RaspberriPI 2/3 blows the
16kb size, making the firmware relocate it in the upper part of memory[1].

There's a way to calculate the new offset of the dtb in memory, but it's
dependent on some config options that an user can modify in config.txt[2],
so the safest upgrade path is:

1) upgrade the raspberry firmware package to a recent version that contains the
"device_tree_address" feature, so we can force a fixed memory location - i
packaged such a firmware in my ppa and named it "raspberrypi3-firmware" since it
contains this feature and add support for the Rpi3 board[3]

2) find a new memory location far from other stuff (e.g. 0x02000000 - 32MB) and
append this to config.txt:

device_tree_address=0x02000000

3) update uboot to find the dtb at the new location:

fdt_addr_r=0x02000000
...
setup=fdt addr ${fdt_addr_r}; fdt get value bootargs /chosen bootargs

4) boot the board, install this kernel and reboot

Given it requires a new firmware, some modification to the boot environment, and
some coordination from people building the Ubuntu (cc: slagansek here) and the
Snappy (cc: ogra here) image, i'm asking you to refrain pulling it until we get
an ack from all parties.

As usual, this release was tested on both my raspi2 and raspi3, and went
through continuous stress test and stress-ng.
