SubjectRe: use generic DMA mapping code in powerpc V4
From
Date
Hi Christoph,

I have found a small workaround. If I add 'mem=3500M' to the boot
arguments then it detects the SATA hard disk and boots without any problems.

X5000> setenv bootargs root=/dev/sda2 console=ttyS0,115200 mem=3500M

Cheers,
Christian
