[ELDK] MCV hardware

[ibragimov]

Hello, I use sysroot

ftp://ftp.denx.de/pub/eldk/5.6/targets/mcvevk/core-image-lsb-sdk-mcvevk.tar.bz2

and DENX_MCV_reference C2

I try to get access to PIO IOB5A through /dev/mem

#define MAP_PIO_BASE_ADDR       (0xFF200000)    ///< lwAxiMaster Base 
Address
#define MAP_PIO_SIZE            (0x00100000)
#define IOB5A_OFFS              (0x000800C0)    // GPIO IOB5A offset 
from lwAxiMaster Base Address

int fd = open("/dev/mem", O_RDWR|O_SYNC);
unsigned int * mem_ptr = (unsigned int*)mmap(NULL, MAP_PIO_SIZE, 
PROT_READ|PROT_WRITE, MAP_SHARED, fd, MAP_PIO_BASE_ADDR);
io_val = mem_ptr[IOB5A_OFFS/sizeof(unsigned int)];

And here I've got Bus error with
Unhandled fault: external abort on non-linefetch (0x018) at 0xb6c590c0


Do core-image-lsb-sdk-mcvevk.tar.bz2 supports HPS PIO of 
DENX_MCV_reference C2 ?
