Hi all,
This is the latest set of patches that introduces NAND boot support for the i.MX31 CPU in general and the PDK board especially.
The patches apply on u-boot next and u-boot-arm next.
I've taken care of all comments received (at least I think so) and changes from the previous version include: * Moved init of i.MX31 UART+SPI to a devices.c file which other boards can use as well * Included JC's macros.h file which contains macros to be used by assembly code * Renamed nand_boot_mx31.c to nand_boot_fsl_nfc.c since it's probable that this can be used by other SoCs as well (e.g. mx27?) * The nand_boot_fsl_nfc.c uses a struct for the NFC and read/write operations without volatile. * Made the lowlevel_init.S somewhat easier to understand.
The code boots on i.MX31 PDK board using large page NAND, it should work for small page NAND as well but that has not been tested.
Regards, Magnus Lilja
