I'm trying to compile latest U-Boot to mx28evk (rev D) with NAND

error is popped up.
MX28 EVK has no NAND, right?
MX28 EVK has NAND slot and I have installed NAND chip on it. I'm using
same chip with older pached U-Boot and Linux and chip is working fine
with them.
Otherwise, check if you have APBH DMA enabled in your
include/configs/mx28evk.h
Config file include/configs/mx28evk.h has following line.
#define CONFIG_APBH_DMA
And you have dcache and icache disabled ?
Yes, they seem to be disabled:
#define CONFIG_SYS_ICACHE_OFF
#define CONFIG_SYS_DCACHE_OFF
I'm using latest U-Boot and default mx28evk.h config:
http://git.denx.de/?p=u-boot.git;a=blob;f=include/configs/mx28evk.h;h=02f3366ed263ff66fe3b9b2089ec95ef461a92c0;hb=HEAD
I have added only NAND related lines I sent in first message.
BR,
Lauri
