[PATCH v3 0/6] NVMeoFC support on Grub

[Avnish Chouhan <avnish@linux.ibm.com>]

This patch series adds support of NVMeoFC on grub. It consists of six
patches.

Patch 1/6 (0001-ieee1275-powerpc-implements-fibre-channel-discovery-.patch):
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.

Patch 2/6(0002-ieee1275-powerpc-enables-device-mapper-discovery.patch):
This patch enables the device mapper discovery on ofpath.c. Currently,
when we are dealing with a device like /dev/dm-* the ofpath returns null
since there is no function implemented to handle this case.
This patch implements a function that will look into /sys/block/dm-*
devices and search recursively inside slaves directory to find the root
disk.

Patch 3/6(0003-ieee1275-implement-FCP-methods-for-WWPN-and-LUNs.patch):
This patch enables the fcp-targets and fcp-luns methods which are
responsible to get WWPNs and LUNs for fibre channel devices.
Those methods are specially necessary if the boot directory and grub
installation are in different FCP disks, allowing the dev_iterate()
to find the WWPNs and LUNs when called by searchfs.uuid tool.

Patch 4/6(0004-change-partition-parser.patch):
Usually grub will parse the PFW arguments by searching for the first occurence of the character ':'.
However, we can have this char more than once on NQN.
This patch changes the logic to find the last occurence of this char so we can get the proper values
for NVMeoFC

Patch 5/6(0005-ieee1275-add-support-for-NVMeoFC.patch):
This patch implements the functions to scan and discovery of NVMeoFC.

Patch 6/6(0006-ieee1275-ofpath-enable-NVMeoF-logical-device-transla.patch):
This patch add code to enable the translation of logical devices to the of NVMeoFC paths.
