tools/hv: Fix /var subdirectory

Initial patch by Ben Hutchings <ben@decadent.org.uk>

We will install this in /usr, so it must use /var/lib for its state.
Only programs installed under /opt should use /var/opt.

This patch adds support for bitstream configuration (programming /
loading) of the Lattice ECP3 FPGA's via the SPI bus.

Here an example on my custom MPC5200 based board:

$ echo 1 > /sys/class/firmware/spi0.0/loading
$ cat fpga_a4m2k.bit > /sys/class/firmware/spi0.0/data
$ echo 0 > /sys/class/firmware/spi0.0/loading

leads to these messages:

lattice-ecp3 spi0.0: FPGA succesfully configured!

misc: st_core: Error triggered by convert "char" to "int"

When st driver decodes protocol index received from raw data,
it does a value convert from "char" to "int". Because it's sign
extension from bit8 to bit32, the "int" value maybe minus, in

Julia Lawall [Thu, 6 Dec 2012 23:15:24 +0000]
drivers/w1/masters/mxc_w1.c: use devm_ functions

The various devm_ functions allocate memory that is released when a driver
detaches.  This patch uses these functions for data that is allocated in
the probe function of a platform device and is only freed in the remove
function.

At the same time, this fixes two faults.  First, mdev, the result of
kzalloc, was never freed.  Second, on failure of ioremap, 0 was returned.
This has been replaced by -EBUSY, which was the failure value for the call
to request_mem_region, with which the call to ioremap has been combined.

The warning message on failure of ioremap is dropped, because
devm_request_and_ioremap already gives such messages on failure.

Finally, the initial call to platform_get_resource is moved closer to the
call to devm_request_and_ioremap, which takes care of checking whether its
result is NULL, implying that a test on the result of this call to
platform_get_resource is not needed.

handler.

v2: Instead of grabbing the bdev->fence_lock in object_transfer just
move the single callsite of that function a few lines, so that it is
protected by the fence_lock. Suggested by Jerome Glisse.

ARM: highbank: fix secondary boot and hotplug

With commit 384a290 (ARM: gic: use a private mapping for CPU target
interfaces), wake-up IPIs now go to all cores as the gic cpu interface
numbering may not follow core numbering. This broke secondary boot on
highbank since the boot address was already set for all secondary cores,
this caused all cores to boot before the kernel was ready.

Fix this by moving the setting of the jump address to
highbank_boot_secondary instead of highbank_smp_prepare_cpus and
highbank_cpu_die. Also, clear the address when we boot. This prevents
cores from booting before they are actually triggered and is also necessary
to get suspend/resume to work.

ARM: dts: fix highbank cpu mpidr values

With the addition of commit a0ae0240 (ARM: kernel: add device tree init
map function), the cpu reg values must match the cpu mpidr register or we'll
get warnings. For some reason, the CLUSTERID on highbank is 9, so the reg
value needs to be 0x90n to quiet the warnings.

While device_type is considered deprecated, it is still needed for tools
