Subject: [PATCH] ieee1275/powerpc: implements fibre channel discovery for
|
|
ofpathname
|
|
|
|
grub-ofpathname doesn't work with fibre channel because there is no
|
|
function currently implemented for it.
|
|
This patch enables it by prividing a function that looks for the port
|
|
name, building the entire path for OF devices.
|
