Hi. I'm trying to keep a small trace buffer over re-boots of linux from ppcboot, so give a mem=31M flag to linux kernel. Yet by the time linux is up, it has overwritten that memory anyway.. PPCBOOT is properly leaving it be (with PRAM feature) and correct arg. goes to kernel..
After 'reboot' from linux, the memory contents of the last meg are still valid (in ppcboot) but by the time linux is back up, the region has been trashed. Why? Help, please. How to prevent linux from talking to that memory region during bootup? -- David Updegraff / dave at cray.com ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
