  This hook loads the necessary modules for an raid root device,
  and assemble the raid device when run.

  Kernel Parameters:
  Specify all your md arrays with md= parameter:
  ::: Example ::: md=0,/dev/sda3,/dev/sda4 md=1,/dev/hda1,/dev/hdb1
  This will setup 2 md arrays with persistent superblocks

  Setup:
  - for old raid arrays without persistent superblocks:
    md=<md device no.>,<raid level>,<chunk size factor>,<fault level>,dev0,dev1
  - for raid arrays with persistent superblocks:
    md=<md device no.>,dev0,dev1,...,devn

  Parameters:
  - <md device no.> = the number of the md device: 
    0 means md0, 1 means md1, ...
  - <raid level> = -1 linear mode, 0 striped mode
    other modes are only supported with persistent super block
  - <chunk size factor> = (raid-0 and raid-1 only):
    Set  the chunk size as 4k << n.
  - <fault level> = totally ignored
  - <dev0-devn>: e.g. /dev/hda1,/dev/hdc1,/dev/sda1,/dev/sdb1
