This patch prevents the needless switching on and off of PLL bypass
mode. With this patch in place, single-stepping through the SPL is
now possible.

Why did FSL have it in the bootlets though? Fabio, can you explain?

Anson (in Cc) explained the following:
"The switch of CPU clock is to make our EVK board can boot up the
uboot and kernel with less than 100mA power consumption to meet the
USB specification, because there is chance that the EVK board is power
by USB cable only, we need to make sure in this scenario, before USB
enum done, the total power consumption for our EVK board should be
less than 100mA, but if CPU running with PLL on, the power consumption
is > 100mA under uboot, so we need to disable PLL and switch CPU clock
to XTAL before USB enum done."

And by running off XTAL, the consumption grows so dramatically?

No, switching on the PLL does.
And the PLL can use either the external XTAL or the internal ring-
oscillator as a reference. The external XTAL is very accurate, but
uses power. The ring-oscillator is not very accurate, but very
energy efficient.
On the EVK, the external XTAL cannot be powered down
separately, so if it's consuming power anyway, there\s not reason
not to use it over the ring-oscillator. But a more generic design
may want use ring-oscillator initially.

Ok, but you switch it back to PLL after the power supply was configured. And
then the consumption grows back.

You're right, but I'm not switching back to XTAL. I'm just postponing the switch to PLL. Not
in the last reason because the first switch to PLL is incorrect (and shouldn't even work).

That's actually a very good point. For that scenario we may even consider
to use the SoC's internal 24MHz ring oscillator instead of the crystal.
But this also means that we should disable bypass mode either a whole lot
later, or make it depend on CONFIG_USB.

I'm trying to reproduce, but my workspace no longer builds after a pull... The set
obviously works in my own workspace, so I'm trying to figure out the problem.

Did you even test before submitting? Also, I think if I remove patch 3, it all
works fine.

Naturally, I did. Yet on my own SVN controlled workspace, because my
GIT workspace of the mainline didn't build yesterday.
I'm looking at the differences now, and there aren't any concerning i.mx28.
But we're going on...

The problem is in here:
io_reg = MXC_IOCLK1 - io; /* Register order is reversed */
I will rework and resubmit the patches 'soon'. I'm a bit numb of reworking and resubmitting and I just received a board to bringup last week, and that's got my priority.
BTW: It seems that mx28evk DDR2 is overclocked a bit. For example tRCD is set to 3, where it should be. I didn't look into all the other settings yet, because lowering the clock helps for my board, for now.

git rebase -i HEAD~3
(if you have the patch you want to rework 3 patches deep)
Change "pick" to the left of the patch to "edit"
Do the change in the file.
git add <file>
git rebase --continue
<submit>

Lowering the clock to what ? I was pondering about this too, the settings in
spl_mem_init are for DENX m28 board, so maybe someone should abstract that out.

May be tonight, at my hotel room.

Down to 137MHz works for me. That's way too low, but at least it keeps my board
going.
But there's nothing wrong with a frequency of 206MHz, as configured currently; We
just should up the CAS to RAS delay to 5 cycles, from the 3 configured currently.
Perhaps others parameters need a little attention too, but there are so many registers
for DDR to check here...

I'm not happy with it either, but the way it is now seems to be the most common one.
And due to the huge amount of registers, I doubt if it could be abstracted nicely,
without turning it into an even bigger mess. I'm afraid there's little alternatives to tuning
DDR parameters for each board separately.
Cheers,
Robert.
