NOTE: I'm seeing issues when this is compiled into U-Boot. U-Boot won't boot on
my MX53 board and will hang right after printing "DRAM:" and before printing the
CPU info. I suspect it's some kind of unaligned access.

NOTE2: I fixed a few complaints from GCC and rebased on top of master.

I was seeing the same problem and this patch fixed it:
http://git.denx.de/?p=u-boot/u-boot-imx.git;a=commit;h=1411fb37b5a8d56bececc5e6ea09d2e0670b9810

Let me know if this fixes the issue you are seeing.

OK. I'm waiting for your test results. It works for me on i.MX51 with 2012.07.

Which ones? I don't see any such change in this new version.

OK.

Here it was uint16_t in my last version, and this was correct since this is code
for MXC_NFC_V1. This change should not hurt, but it was not necessary.

Is this change related to the GCC complaints that you mentioned?

The other changes (i.e. the rebase) are fine with me.

Nowhere, it's a typo.

It works with 2013.01-rc1, but I have issues. When I boot the board from SD, it 
hangs. When I load via JTAG, it doesn't hang. I suspect it's something related 
to the MXC NAND driver, since if the driver is not compiled in, it works like 
charm both ways.

Otherwise, when booted, the NAND works fine.

I wonder if there's some unaligned access or something happening in the NAND 
driver. Or maybe some other issue where the code is miscompiled.

This one I think:

But in case readnfc() results in readl(), u16 is too small.

No, there's one more, see above.

I hope I didn't screw up the attribution. I used "From:" which I hope is 
correct.

I have that applied, but still seeing the issue. Maybe there's some additional 
problem with the NAND driver ?

Or there is something wrong with the Flash header or SPL?

This is just the rebase. Or perhaps you started from
http://patchwork.ozlabs.org/patch/177098/ instead of
http://patchwork.ozlabs.org/patch/179176/.

readnfc() always results in readw() for MXC_NFC_V1, so u16 is just fine here.

It's correctly filled, but I don't know if it's used by U-Boot's Git process. I
have already seen this "From:" used before.

It is used by git.  git format-patch generates it when the patch author  
is different from the e-mail sender, and git am uses it as the commit  
author if present.

Did you have a chance to further investigate this hang issue with non-JTAG boot
and the NFC driver compiled in?

I recall there being some patch from Scott and there was a guy on IRC who met 
this issue too (can you join irc? #u-boot @ irc.freenode.net). No activity on 
this from my side, since the issue magically disappeared once and didn't pop up 
again (weird, I know).

Best regards,
