This patch add initial support for freescale MX53LOCO board.
Network(FEC),SD/MMC, UART have been supported by this patch.

Signed-off-by: Jason Liu <jason.hui@linaro.org>
---
changes since v4:
- remove the boot reset cause from board support
changes since v3:
- include other two small patch into this commit,
mx53loco: set mmc env to MMC slot1
MX5: Enable flat-device-tree support on mx53 loco board
changes since V2:
-factor out the boot cause function to common code,
-fix gd->ram_size with full memory size
-remove the '1' from all #defines that just enable features
-correct memory test end address value

Rereading the thread regarding this board I see there is an open
question issued by Wolfgang about this code, if accessors should be used
in this case. IMHO the code is correct, using the GPIO get function to
acquire the current value of a pin. Wolfgang, is it enough to answer
your question ? Do you see an open issue ?

If I am not confused, this setup is not valid as you already sent a
patchset to drop these lines and adding support for the DA9053 pmic.

	PMIC: Add dialog pmic support
	MX53: loco: Add power init support

As this patchset is based on the LOCO patch (this one), and it does not
apply anymore, please drop these lines and rebase your patches to add
pmic support on the actual state of the current patch.
IMHO it should be better if you resend them as a single patchset, as
they are strictly related, merging "Add power init support" inside this
patch.

There is still an open question about this range. Can you answer to
Wolfgang's question ?

OK, I will resend the patchset as the following layout:

MX5: clock: Add clock config interface
MX5: factor out boot cause funciton to common code
PMIC: Add dialog pmic support
MX53: support for freescale MX53LOCO board (merge "Add power init support")

I will rebase on the u-boot-imx git, do you think is it OK?

In fact, I want to give one simple test range when use mtest, I don't know
what you are worrying about, please tell it clearly?

I just noticed that MX5: factor out boot cause funciton to common code
has been applied.
So, I will send out the following,

MX5: clock: Add clock config interface
PMIC: Add dialog pmic support
MX53: support for freescale MX53LOCO board (merge "Add power init support")

Any comments?

Yes, thanks.

I think the only issue is if there is some reasons to set the test range
to only 64KB, except the fact this was the value set for the mx51evk. If
you do not see any special reasons, you could increase the
CONFIG_SYS_MEMTEST_END to a larger value.

Is there any rule that we need must follow to set the
CONFIG_SYS_MEMTEST_START
CONFIG_SYS_MEMTEST_END ??

If no, I think the value we set is free. Here I set for 64KB is just
for simple and quick
test, there is no other reasons.

In fact, mtest command line can override the value.

What the value you think I need set?

There is no rule, it was only a question if there are some specific reasons.

That is correct.

As I said, there is no rule. You choose the value you think it is better
for your board as default values for mtest.

The only strict rule is that the test must work with the defined area.

My recommendation is to set a range that is as big as possible for
the given system, so the default call of the mtest command will
actually test all (well, most of) the present RAM.

Agree, I have tested it and it works.

As I said, I just want the user to do one quick test for the memory.
I don't think it need be set as big as possible.

Since there is no other rule I need follow for setting such value, So
I will keep as it's.
