[U-Boot] relocation problem on powerpc

Hi All,
I have come across what I think is a relocation problem for powerpc.
I've added the following to ArpTimeoutCheck
+ printf("NetArpWaitTimerStart = %ld\n", NetArpWaitTimerStart);
+ printf("&NetArpWaitTimerStart = %p\n", &NetArpWaitTimerStart);
+ printf("NetArpWaitTry = %d\n", NetArpWaitTry);
+ printf("&NetArpWaitTry = %p\n", &NetArpWaitTry);
+ printf("NetArpWaitTxPacketSize = %d\n", NetArpWaitTxPacketSize);
+ printf("&NetArpWaitTxPacketSize = %p\n", &NetArpWaitTxPacketSize);
Which yields the following output
NetArpWaitTimerStart = 0
&NetArpWaitTimerStart = f00000d0
NetArpWaitTry = 1
&NetArpWaitTry = 7ffb0058
NetArpWaitTxPacketSize = 42
&NetArpWaitTxPacketSize = 7ffb0078
That looks to me like NetArpWaitTimerStart hasn't been relocated for
some reason. Looking at my u-boot.map NetArpWaitTimerStart is the last
item in the .sbss section
Here's the relevant snippets for the variables I'm displaying
0x00000000f0000058 NetArpWaitTry
0x00000000f0000078 NetArpWaitTxPacketSize
0x00000000f00000d0 NetArpWaitTimerStart
The actual problem for me is that ARPs timeout and various network
things fail. Has anyone got any clues as to why this one particular
variable isn't getting relocated.
Thanks,
Chris
