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.

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.

- add building of a standard uImage along with the combined kernel+rootfs
- remove 'old' image build - that was for a very old and obsolete bootloader
To update the bootloader for GW2387,GW2388,GW2391 (NOR Flash) from uboot:
put latest NOR bootloader on tftp server:
http://svn.gateworks.com/laguna/trunk/images/u-boot_nor.bin

To update the bootloader for GW2380,GW2382,GW2383 (SPI Flash) from uboot:
put latest SPI bootloader on tftp server:

In order to support both normal images and initramfs, ensure that each
target sets KERNELNAME properly so that the generic kernel building code
can copy the corresponding files over $(KDIR) with the appropriate
extension. Update the various paths to the kernel and wrapper images
from $(LINUX_DIR)/arch/$(ARCH)/boot/$(foo) to $(KDIR)/$(foo).

When an rx interrupt comes in, rx interrupts are disabled and NAPI
polling is scheduled. During the NAPI poll, the driver first processes
received frames in the ring, then fills the dma descriptor slots with
new buffers and calls tx complete, before finally re-enabling rx
interrupts and completing NAPI (if below the budget).
If the hardware rx queue overflows before the napi complete is called,
the hardware will not throw any further rx interrupts and rx processing
stops completely.
Fix this by keeping NAPI polling scheduled until it completes a poll
without receiving any packets, and also handle NAPI completion before
refilling rx or completing tx.
