Could you describe better which is the current status for this porting and define what is already supported ? I mean, "work-in-progress" tells me nothing about which peripherals are working and which not. Could you add to your commit-id a short description, adding on which hardware u-boot is running (on the development board ? on efika smarttotp ? on efiga smartbook ? on all of them ?), and which peripherals are currently supported.
You should add your name to the MAINTAINERS file, too.

Is there a reason why CONFIG_MXC_SPI is not set ? As I understand, it is required to set the PMIC to make things working. If CONFIG_MXC_SPI, something wrong happens. I would prefer you drop the #ifdef, and instead of that you add a check at the beginning of the file reporting a compiler error if CONFIG_MXC_SPI is not set.

I see, I let this useless CONFIG_ when I developped the vision2 board. However, CONFIG_FSL_SF is not used at all in u-boot. It was a test I made using a SPI flash driver from Freescale's code. You should drop it, and I have to do the same for the vision2.

Is it possible that the efika use exactly the same gpio (GPIO4_25) as the vision2 board, or it is only a cut&paste error ?
+#define __io
I think we have already discussed abot this define. Should it not move to another file, such as imx-regs.h ? Or is there a better solution ?

Why fix ?
Ah, that's because I used SD card to boot it, it should officially boot from SPI nor. Fixed in v2

Move this define before including imx-regs.h. Patches for mx53evk are currently merged in u-boot-imx, and the imx-regs.h file has an #ifdef CONFIG_MX51 switch to define the different offsets for the two processors.

I see, I let this useless CONFIG_ when I developped the vision2 board. However, CONFIG_FSL_SF is not used at all in u-boot. It was a test I made using a SPI flash driver from Freescale's code. You should drop it, and I have to do the same for the vision2.

Is it possible that the efika use exactly the same gpio (GPIO4_25) as the vision2 board, or it is only a cut&paste error ?
seems to be the same.
+#define __io
I think we have already discussed abot this define. Should it not move to another file, such as imx-regs.h ? Or is there a better solution ?
The thread where we discussed this got deaf. I tried asking further, but no reply :-(

Thanks for the review, it helped greatly.
Cheers

Is it ok to leave the NAND pins configured as GPIO, or should they set back for the NFC controller ?
I don't think there is even NAND used on efikamx. Though I might be mistaken.
Understood, then I agree to leave the iomux set with gpios.
Replace fix constants with defines, adding them to mc13892.h if they are missing.
Is any sane datasheet for this thing available ? If so, can you link me to it please?
There is a datasheet, I do not know if you can consider it "sane" ;-)
http://cache.freescale.com/files/analog/doc/data_sheet/MC13892.pdf?fpsp=1
The register description is quite spread in the manual. You can see the complete SPI Bitmap on pages 118-121.
I have already set most constants in include/mc13892.h, probably there are some missing.

Agree, I remember the issue, I do not remember any decision. Anyway, I think the position of this macro is wrong. It is related to the processor, that can have it or not, and it is not related to the board. I see that in u-boot __io is defined in board configuration file, but I do not think it is correct.
At least I will suggest to move this define in the processor related file (-->imx-regs.h).

This is a problem, if __io is defined there, it won't be defined in the ide driver.

As these array are only used here, they should be static.

Ditto.
