We do not need to invalidate the cache in the poll loop anymore
since the corresponding bit is now in a dma coherent area. Instead,
flush cache before hardware operation and invalidate afterwards. Put
the corresponding code inline since it's shorter.

There's no point in syncing them manually. Instead, use

This is another variant of:
USB gadget fsl: request cacheline aligned buffer
The fsl udc driver allocates a buffer for small requests. The
driver then calls dma_inv_range later on it. This buffer happens
to be not cacheline aligned which means that a dma_inv_range can
corrupt other memory around the buffer.

Some drivers call dma_inv_range() on buffers, on arm these buffers must
be cache line aligned. This patch introduces a generic dma_alloc,
dma_free. Archs can implement in their own functions in "asm/dma.h" and add a:
#define dma_alloc dma_alloc
#define dma_free dma_free
On all other archs the generic versions, which translate into xmalloc
and free are used.

This variable is set in /env/init/general and then used
in /env/boot/* which is a bit confusing. Also it does not
necessarily have to be a tftp path (could be nfs aswell).
Use a local variable in the scripts using it instead to make
the meaning a bit more clear.

if serverip is specified, also overwrite eth0.serverip in dhcp
case. This makes it possible to specify a different serverip
when the dhcp server returns the wrong ip (because the DHCP
might be a DSL router which does not provide tftp).

To get symbols like __ashrdi3.
Franck started generating these symbols from gcc assembly, which seems
to be the cleaner approach. The simpler approach for now to get additional
symbols is to link in libgcc, which is the same as the kernel does.

The Linux Kernel defines only one of __LITTLE_ENDIAN and
__BIG_ENDIAN. Endianess can then be tested with #ifdef __xx_ENDIAN. Userspace
always defined both __LITTLE_ENDIAN and __BIG_ENDIAN and byteorder can then
be tested with #if __BYTE_ORDER == __xx_ENDIAN.
As we tend to use a lot of Kernel code in barebox we switch to use the kernel
way of determing the byte order.
As this always causes a lot of confusion add a check to include/common.h to
make sure only one of __LITTLE_ENDIAN and __BIG_ENDIAN is defined.
