This processor only have one FEC and its MDIO pins are
located at a different offset than the code used for
the current CONFIG_M527x.

Tesed on M5271EVB eval platform.
Without this patch the FEC driver will report no PHY attached
if the bootloader does not pre-initialize the PAR_FECI2C GPIO register.

There is a couple of problems with the UART vector setup for the 5307
ColdFire UART. The ICR register access should be 8bit, not 32bit. The
address of the UIVR register is wrong, it needs to be offset into the
MBAR register region. Fix these.

Part of the code that did not make sense to me got removed by Greg.
This is part two:

The first compare is to check whether the interrupts are disabled or not.
Depending on the result we exectute the RESTORE_ALL macro is not only
restoring the stack but also returning to caller.
The test for pending softirq has been removed because it is allready done
in irq_exit().
Since system_call() is allso using the SAVE_ALL macro and returning via
ret_from_exception label I see no reason why we could not do this here
as well. This is also handy because if we return from the timer interrupt
and we need to resched than we check for this :)

Impact: change calling convention of existing clock_event APIs

struct clock_event_timer's cpumask field gets changed to take pointer,
as does the ->broadcast function.

Another single-patch change.  For safety, we BUG_ON() in
clockevents_register_device() if it's not set.

Switch the ColdFire head start up code to be in the .text.head segment.
And make sure that segment is at the start of the final linked text
segment. Fixes the linker warnings about section use mis-matches:

  WARNING: vmlinux.o(.text+0xa8): Section mismatch in reference from the variable _clear_bss to the function .init.text:start_kernel()
  The function _clear_bss() references
  the function __init start_kernel().
  This is often because _clear_bss lacks a __init
  annotation or the annotation of start_kernel is wrong.

The coldfire timer must be initialised to n - 1 if we want it to count n
cycles between each tick interrupt.  This was already fixed, but has been
lost with the conversion to GENERIC_TIMER.
