The driver uses a static int once variable to alloc the
rx packets. remove this to make the driver multi instance
safe. While at it, remove the crappy selfmade alignment.
dma_alloc_coherent returns sufficiently aligned memory.

as barebox can be run as a second stage the first stage may have init it
before so re-used it

Add the option for the FEC on MX28 as well.

We never supported the sigmatel stm chips and probably
never will. So do the first step and rename the architecture
to mxs just like in the kernel.

Ethernet PHY devices have 32 registers, each 16 bits wide. Thus, the size of
the phy device should be 64 bytes.

The idea is to panic() when there is no memory available for normal
operation. Exception: code which can consume arbitrary amount of RAM
(example: files allocated in ramfs) must report error instead of panic().
This patch also fixes code which didn't check for NULL from malloc() etc.
Usage: malloc(), memalign() return NULL when out of RAM.
xmalloc(), xmemalign() always return non-NULL or panic().

The i.MX28 comes with an extended ethernet controller (ENET/FEC) which
is backwards compatible to the FEC known from other i.MX CPUs. Add a few
adaptions to the existing driver to make it work with the MX28 FEC.

Some register bits are not defined in the IMX CPUs using this FEC (at least
I did not find anything about them in the related datasheets) and they will
get (partially) a new meaning in the i.MX28 CPU. So, removing them from the
source seems the best way to avoid any accidental usage on i.MX28.
