From 72b845e04e99298e5179b31e8de16afed52a2627 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Tue, 14 Mar 2006 14:11:48 -0800 Subject: [PATCH] [TG3]: Do not try to access NIC_SRAM_DATA_SIG on Sun parts. Sun does't put an SEEPROM behind the tigon3 chip, among other things, so accesses to these areas just give bus timeouts. Signed-off-by: David S.
