[U-Boot] hwmon init

[Heiko Schocher <hs@denx.de>]

Hello,

Is there a reason why the dtt sensors are initialized and accessed on
u-boot startup?

The U-Boot Design Principles[1] clearly say:

  Initialize devices only when they are needed within U-Boot, i.e. don't
  initialize the Ethernet interface(s) unless U-Boot performs a download
  over Ethernet; don't initialize any IDE or USB devices unless U-Boot
  actually tries to load files from these, etc. (and don't forget to
  shut down these devices after using them - otherwise nasty things may
  happen when you try to boot your OS).


Should that be changed?

bye,
Heiko
