Hi Kevin,

In  board/smdk2410/smdk2410.c I have added these lines:

#elif FCLK_SPEED==2              /* Fout = 200MHz */
#define M_MDIV  0x5c
#define M_PDIV  0x4
#define M_SDIV  0x0

and I have redefine FCLK_SPEED to 2.

2410_NAND_BOOT but  do not include any  dosumentation.  At  least,  please  provide  an  explantion  of these options for the README fie. If you feel longer  explanations are needed create a new file  doc/README.NAND-Boot  or  so.David, I've forwarded the patch to you. Can you please have a look atthe implementation details?
