Please use the nand_spl infrastructure to whatever extent is practical.
Does this code really need to be in assembly to fit?

I reused the source code from RedBoot. I think using nand_spl is the best approach, but it will needs more effort to complete.
I am afraid about the 2KB NAND loader limitation, this is too tight to fill using C code. I will investigate to verify if it is feasible.
Anyway, right now we can have iMX31PDK booting with this code as an option for users willing to use U-Boot in this board.

I've updated the patch and it now almost compiles. There's a problem at the last link stage where gnu-ld complains about multiple __udivsi3 definitions and incompatible EABI formats (see below, modulo gmail wrapping).
I can compile the imx31_litekit just fine and that board is very similar to the initial mx31pdk board.
Any ideas on what may be causing this?

PATCH 3/3 iMX31: Add support to iMX31PDK board boots from NAND Flash
Dear Magnus,
Quoted 5 lines · In message <[email protected]> you…
I've updated the patch and it now almost compiles. There's a problem at the last link stage where gnu-ld complains about multiple
__udivsi3definitions and incompatible EABI formats (see below, modulo gmail wrapping).
Try this patch which I posted today:
ARM: Use do_div() instead of division for "long long".
Best regards,
Wolfgang Denk

That patch doesn't seem to touch any files that are involved in building i.MX31 boards. I might try the equivalent change though. Although it is a bit puzzling that I can build the i.MX31 Litekit board with the same toolchain.

Ok, I've found what's triggering this. The PDK board has CONFIG_MX31_CLK32=32768 while Litekit has CONIFG_MX31_CLK32=32000. That difference nowadays causes problems when linking, I suppose that happened after the merging of CONFIG_MX31_TIMER_HIGH_PRECISION.
Changing the TICK_TO_TIME macro in arm1176/mx31/interrupts.c to a construction that uses do_div() solves the problem.
I don't have the PDK schematics here but since I decided to set CLK32 to 32768 I suppose the board uses that frequency.
I haven't tried my new patch on real hardware yet, but I'll do that tomorrow and post a patch (without the do_div() fix though, perhaps someone else can do that?).

Yes, I confirmed with the schematics. There is a 32768kHz crystal connected to the PMIC that drives the MX31 clock.

Ok, the patches have been posted now. The first one is a quick workaround for the div-problem, if someone has a better solution please use that instead. The second one is my updated basic i.MX31 PDK patch, now rebased and tested on hardware using a JTAG debugger to load it.
