Subject: [PATCH] ieee1275/ofdisk: retry on open failure
This patch aims to make grub more robust when booting from SAN/Multipath disks.
If a path is failing intermittently so grub will retry the OPEN and READ the
disk (grub_ieee1275_open and grub_ieee1275_read) until the total amount of times
specified in MAX_RETRIES.
