We need to set bits 28 and 29 in P9 CFAM reg 0x2918 to get P9 to boot properly. However, pdbg can't seem to access that register on a read or write:
# pdbg -a -b fsi -d p9w getcfam 0x2918
getaddr: Error reading register
No valid targets found or specified. Try adding -p/-c/-t options to specify a target.
Alternatively run pdbg -a probe to get a list of all valid targets
What I want to put in the scripts is: pdbg ... putcfam 0x2918 0x0000000C 0x0000000C
Alistair has already been investigating this, but I was asked to open this issue so people can track it.
