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.
