Dear Benoît Thébaudeau,
[...]
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.
OK. I'm waiting for your test results. It works for me on i.MX51 with 2012.07.
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.
Or there is something wrong with the Flash header or SPL?
Flash header? SPL is not used, I boot from SD.
NOTE2: I fixed a few complaints from GCC
Which ones? I don't see any such change in this new version.
This one I think:

This is just the rebase. Or perhaps you started from http://patchwork.ozlabs.org/patch/177098/ instead of http://patchwork.ozlabs.org/patch/179176/.
Lemme try the V2, thanks. [...]
