Now that GCC 4.8 is the default, make sure that we have the relevant
memset fixes to avoid nasty kernel crashes.

sizeof(array_from_function_definition) gives back the size of the pointer.
sizeof(type) * array_size should be used in memset.

The uImage target will always fail on a clean build due to dependency issues.
Building the uImage isn't necessary anyway as its re-built with correct
entry points in image/Makefile so remove it.

Update our copies of the brcm2708 patches to the latest rpi-3.10-y
rebased against linux-3.10.y stable (3.10.32). This should hopefully
make it easier for us in the future to leverage the raspberry/rpi-*
branches.

We already clean up tx descriptors in the napi eth_poll() function so it
would likely be rare to run out of available descriptors in eth_xmit. Thus
we can clean them up only when needed and return busy only when we
still don't have enough.

The combination of r35942 and r35952 causes an issue where eth_schedule_poll()
can be called from a different CPU between the call to napi_complete() and the
setting of cur_index which can break the rx ring accounting and cause ethernet
latency and/or ethernet stalls. The issue can be easilly created by adding
a couple of artificial delays such as:

This patch moves the setting of cur_index back up where it needs to be and
addresses the original corner case that r35942 was trying to catch in an
improved fashion by checking to see if the rx descriptor ring has become
full before interrupts were re-enabled so that a poll can be scheduled again
and avoid an rx stall caused by rx interrupts ceasing to fire again.

The IMX6 SoC uses an ARM Cortext-A9 which has both NEON and VFPv3 hardware
blocks. This will tune gcc to use neon instead of vfpv3 which will outperform
VFPv3.

The OpenWrt build system uses MACHINE_FEATURES of fpu to set the HAS_FPU which
in turn sets the default of CONFIG_SOFT_FLOAT as well as uClibc configuration.
As the IMX6 SoC has both vfpv3 and NEON hardware support we want to add fpu
to the feature list. This will default the IMX6 target to use -mfloat-abi=hard
which will the be most efficient use of floating point.
When switching to hard float, we also need to enable VFP support in the kernel.

The ar71xx platform always uses the eth0 interface to provide
access to the device in failsafe mode. Due to this, failsafe
access is broken on devices where the LAN ports are connected
to the 'eth1' interface.

for these devices.
