lowlevel_init() of rmobile badly assumed that ip register holds return address.
The commit "63ee53a7 armv7 cpu_init_crit: Simplify code" breaks this assumption.
This patch removes this bad assumption and simplify code.

The IDE_BUS(dev) macro was previously doing dev >> 1.  This however is a
mis-match of the usage in common/cmd_ide.c and would cause boards with
multiple ports / devices to not correctly detect all devices.  For more
details please see:

This patch aims at ensuring that the 2012.10 release works
out-of-the-box on as many targets as possible, by reinstating
commit 5347560f5427bcdd48a563b62180481606ac8044, which adds
option -mno-unaligned-access to armv7 builds.

This patch will be overriden immediately after release of 2012.10.

env default -a -f calls env_check_apply on all existing environment
variables with a NULL value for "newval" as a way of cleaning up.
This causes string manipulation functions to crash on most architectures.
So replace a NULL argument with an empty string.

Due to grown code sizes the TQM85xx boards don't build any more with
some older tool chains (like ELDK 4.2).  As these boards have long
reached EOL it seems a waste of effort trying to fix them.  The vendor
has agreed to drop support for them, too.  So let's get rid of them.

On x86 machines gd is unfortunately a #define, so we should avoid using
gd for anything. This patch changes uses of gd to bgd so that ext4fs
can be used on x86.

A better fix would be to remove the #define in x86, but I'm not sure
how to do that.

Two sub-commands... start and get.
 * start sets the reference.
 * get prints out the time since the last start (in "<sec>.<msec>" format).
If get is called without start, returns time since boot.
