For now, only the sub-command name is completed. No support yet for
completing options to that command. But even this is a huge step as
currently, nothing is completed, and the basic "help sim" is fairly
obtuse as to what exactly the "sim" command accepts.

This simulates a CFI flash. Its pretty configurable via the device
tree. For now, only basic read/write/erase operations are supported
for the Intel command set, but it's easy enough to extend support.
It's certainly enough to trick Das U-Boot into using it for probing,
reading, writing, and erasing.

The sim keeps track of which allocations are zero-ed internally (via
zalloc) and then calls a helper "zfree" function rather than "free".
But this "zfree" function simply calls "free" itself. Since I can
see no point in this and it is simply useless overhead, punt it.
The only real change is in hw-alloc.c where we remove the zalloc_p
tracking, and sim-utils.c where zfree is delete. The rest of the
changes are a simple `sed` from "zfree" to "free".

The sim-events code jumps through some hoops to avoid using 64bit math
to manage the current time. One fundamental assumption here is that by
constantly scheduling the sim poll event a short time into the future,
the 64bit difference will always fall into a signed 32bit value. This
does work most of the time, except for when processing the sim poll event
itself.
Normally, sim_events_process() will dequeue the sim poll event, update
the current time (time_from_event) according to the next pending event,
process the sim poll event (which will then requeue the sim poll event),
and then continue on.
The problem here of course is that the current time is updated in that
small window before the sim poll event gets a chance to reschedule itself.
So if the 64bit difference between the current time and the next event
does not fit into the signed 32bit value, time_from_event overflows, and
the internal assert at the end of update_time_from_event() triggers.
Since attempts at tweaking sim_events_process() logic introduced other
subtle bugs (due to tangled assumptions between most pieces of the sim
time keeping code), change the time_from_event to a real 64bit value.
Tests on my system between a 32bit ELF and a 64bit ELF show no practical
difference (it's all lost in the system noise). Basically, I booted a
Linux kernel to userspace and then paniced it; this gave me a constant
sample size of about 18 million insns.
This was noticed when simulating Blackfin Das U-Boot. The simulated core
timer is given the max unsigned timeout value possible on a 32bit processor
(0xffffffff). This timeout value is used directly to schedule a hw event
in the sim future (the IRQ firing). Once the sim poll event is kicked off,
the next pending event is the core timer event which is more than 2^31
ticks in the future, and the sim aborts with:
sim-events.c:435: assertion failed - current_time == sim_events_time (sd)

I can't find any history for why the call to hw_tree_delete is commented
out, and the VCS history shows that this goes back to the original import
in 2009. I did find some vague reference to it from 2000 (pretty close
to the original import of code), but no actual details.
Without this call, every new instance of the sim results in all old
previously allocated resources being leaked. With some devices, this
isn't just memory, it's things like open file descriptors or mmaps.
So if there are pending issues with this, I'd rather we get the sims
sorted out rather than continuing to leak this stuff. Especially since
the "let's wait for the sims to fix themselves" hasn't actually happened
in the last 10+ years.

The 2nd arg to SIM_AC_OPTION_HARDWARE is described as "a space separated
list of devices that override the defaults" while the 3rd arg is "a space
separated list of extra target specific devices". But the macro doesn't
seem to treat the 2nd arg this way.
Instead, it will always add the default list of devices, and only add the
extra target specific devices if the 2nd arg is not specified. So rework
the logic slightly to handle the 2nd arg as documented.
This shouldn't affect any targets in the tree as no one passes in a non-
empty value as the 2nd arg.

The gdb code always passes down -E <little|big> to the sim core when using
the sim target. But the sim core only recognizes this option when the sim
supports big endian systems. So for little endian simulators, any attempt
to use the sim target fails with:

Since always respecting the option doesn't cause any problems, do just
that. If someone tries to use an invalid endian, they'll get an error
anyways.
