The ESG ima3-mx53 board is based on the Freescale
i.MX53 SOC. It boots from NOR (128 MB) and
supports Ethernet (FEC), SATA.

Ah. I wonder why I was under the impression that I was the only guy 
fighting with the imximage NOR header pain, then ;)

Maybe the above comment should be updated for nor? ;)

I assume that you have tested this and it works with the imximage?

When something goes wrong, it does for everybody...

Yes, I'll do

I have not any problem with the current imximage, so I am quite
confused. Agree that you are fixing a bug, but I have not understood why
I have not seen any issue on my board, a MX53 using V2 image header.

My board boots flawlessly from the NOR interface. I will try to
investigate why and, of course, I will be able to test your patch on my
board.

Can you confirm that your board does not boot ? Or are there other
symptoms ?

Best regards,
Stefano Babic

Hmm, yes, this is quite confusing :(

Yes, removing the imximage fix stops the board from booting. 
Unfortunately it's hard to debug how the boot ROM deals with the header 
information. So either it works, or not, but there is little chance to 
debug :(

For testing, taking the SabreLite (mx6qsabrelite), switching it to NOR 
[1] and then compiling it without and with my imximage fix, results in 
the following difference in the header (disassembly of u-boot.imx):

-      20:      177ff800
+      20:      177fec00

At offset 0x20 in the header, this is the target address in the 
destination memory. Having a header with the size of 0x400 (like here) 
the destination address should be TEXT_BASE - 0x400 (header size) - 
0x1000 (NOR offset), i.e. 0x17800000 - 0x1400. So my understanding is 
that 0x177fec00 is correct for NOR, while 0x177ff800 is valid for all 
FLASH_OFFSET_STANDARD devices.

Best regards

Dirk
