Problems compiling MTD

[Securez]

Hello i'm using uClinux on a MC68VZ328 booting form the flash 
http://www.openhardware.net/Dragonix .
I want to get MTD working to use JFFS on it, but i get this errors:

drivers/mtd/mtdlink.o: In function 
`physmap_read8':/home/devil/new-kernel/uClinux-dist/linux-2.4.x/drivers/mtd/maps/physmap.c:24:

Leaving directory `/home/devil/new-kernel/uClinux-dist/linux-2.4.x'

I redefine this references in include/asm/io.h to solve this, where need to 
go this?? is correct here??

#define __raw_readb readb
#define __raw_readw readw
#define __raw_readl readl
.
..

After this the kernel compiles ok.
I program the flash, and when i reboot, the kernel seems ok, but when a 
message appears in the console:
physmap flash device:40000 at 2000000
The system reboots, :(.

What is happend??
