Unhandled fault: external abort on non-linefetch (0x1028)

[Ran Shalit <ranshalit@xxxxxxxxx>]

Hello,

I am trying to understand how I can enable pm runtime with mcspi.
spi with omap is implemented only for 4-wire device, while we use 3-wire device.
So, I had to implement it myself.
I try to do some porting of code (instaed of modification in current
spi driver),

But - I keep getting exception when accsessing spi status register
(you can find the complete log below).

ioaddr = ioremap_nocache(0x4809A000, SZ_4K);
     *(( unsigned int*) (ioaddr+0)) = 0x12;
    val =  *(( unsigned int*) (ioaddr + 0x34));
printk("mymem 0x%x\n",val); <<--- exception when reading from 0x4809a034

using: omap3530, kernel 2.6.37, custom spi driver
Is there any idea what can be wrong here ?

Thanks,
Ran
