Subject: [PATCH 042/194] sparc64: Don't use devspec to determine the OBP path
Don't use devspec to determine the OBP path on SPARC hardware. Within all
versions of Linux on SPARC, the devspec returns one of three values:
"none", "vnet-port", or "vdisk". Unlike on PPC, none of these values
are useful in determining the OBP path.
Before this patch grub-ofpathname always returned the wrong value
for a virtual disk. For example:
% grub-ofpathname /dev/vdiskc2
vdisk/disk@2:b
After this patch it now returns the correct value:
% grub-ofpathname /dev/vdiskc2
/virtual-devices@100/channel-devices@200/disk@2:b
