Currently we just hang when an initcall fails. This resulted
in most initcalls just returning 0 unconditionally. Instead
of hanging which usually leaves the user without a clue what
happened just continue and hope for the best.

hang() only outputs 'reset the board' whereas panic
can be passed a string which we can use to output
some more information what is happening.

This changes the dynamically allocated kfifos to statically initialized
ones. This makes the console work without malloc and thus safe to be

kfifo currently only works with dynamically allocated fifos.
Change the currently unused kfifo_init to take a preallocated
fifo. This allows for statically initialized fifos.

On my laptop with avahi enabled (linux mdns implementation), the unmount
take quite long, because the avahi daemon tries to resolve the client's
host name. This leads to a delay of about 8 seconds of the unmount reply
messages, so that barebox runs into a timeout. This patch increases the
NFS timeout to 15 to work around the problem.

The timings of the poller calling have changed, digging out
a latent bug in pxa27x udc controller.
The polling routine is called before the probe function is
called, and the driver internal are not initialized at that
time. This triggers a NULL pointer exception.
Fix it by moving poller registration after driver probe.

The document "PC16550D Universal Asynchronous
Receiver Transmitter with FIFOs" (vers. June 1995,
http://www.national.com/ds/PC/PC16550D.pdf) states
that IER (Interrupt Enable Register) is accessible
if the bit DLAB = 0 (DLAB is bit 7 in LCR; in barebox
DLAB known as LCR_BKSE).
So before IER access we need set DLAB to 0.

Remove __attribute__ ((packed)) to prevent byte access to soc

Having patches to enable ehci for the BeagleBoard lying around for

Switched to align(4), rather than remove the attribute, per suggestion
from Alexander.
