Works nice :)

So now we have following forwardtrace:
devm_ioremap_nocache
ioremap_nocache
__ioremap_mode
__ioremap
CKSEG1ADDR

It results in different address than KSEG0ADDR:
[ 1.339752] [bcm47xxsflash_bcma_probe] KSEG0ADDR(BCMA_SOC_FLASH2):9c000000
[ 1.346848] [bcm47xxsflash_bcma_probe] devm_ioremap_nocache:bc000000

But it still works as expected! :)
