[c-nsp] Upgrading 12K IOS XR from 3.6 to 4.2

[ibogzipper iboge]

Thanks Grzegorz,  down time window is the problem to go for 2 steps .
rommon upgrades are in the FPD package but if i want to do the turboboot
there is no way that i can install the new pie c12k-fpd.pie-4.2.4 on 3.6.2
and upgrade the rommon . is there any package that i can copy and upgrade
the rommon like CRS .Cisco document mention about 3.x to 4.x with
c12k-upgrade.pie-4.2.4 package but still confusing about direct 4.2
upgrade.
