b88e7b3cc0 hwmon: Provide dtt_init()
Our boards rely on dtt for initialization of fan hardware.
dtt_init() was implemented to be called form board specific code.

780f13a9e1 hwmon: do not init sensors on 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).

So, do not initialize and read the sensors on startup.

1c6fe6eac7 hwmon: Add LM63 support
This patch adds support for the National LM63 temperature
sensor with integrated fan control. It's used on the GDSys
Neo board (405EP) which will be submitted later.

6dd652fa4d Patches by Murray Jensen, 17 Jun 2003:
- Hymod board database mods: add "who" field and new xilinx chip types
- provide new "init_cmd_timeout()" function so code external to
  "common/main.c" can use the "reset_cmd_timeout()" function before
  entering the main loop
- add DTT support for adm1021 (new file dtt/adm1021.c; config
  slightly different. see include/configs/hymod.h for an example
  (requires CONFIG_DTT_ADM1021, CONFIG_DTT_SENSORS, and
  CFG_DTT_ADM1021 defined)
- add new "eeprom_probe()" function which has similar args and
  behaves in a similar way to "eeprom_read()" etc.
- add 8260 FCC ethernet loopback code (new "eth_loopback_test()"
  function which is enabled by defining CONFIG_ETHER_LOOPBACK_TEST)
- gdbtools copyright update
- ensure that set_msr() executes the "sync" and "isync" instructions
  after the "mtmsr" instruction in cpu/mpc8260/interrupts.c
- 8260 I/O ports fix: Open Drain should be set last when configuring
- add SIU IRQ defines for 8260
- allow LDSCRIPT override and OBJCFLAGS initialization: change to
  config.mk to allow board configurations to override the GNU
  linker script, selected via the LDSCRIPT, make variable, and to
  give an initial value to the OBJCFLAGS make variable
- 8260 i2c enhancement:
  o correctly extends the timeout depending on the size of all
    queued messages for both transmit and receive
  o will not continue with receive if transmit times out
  o ensures that the error callback is done for all queued tx
    and rx messages
  o correctly detects both tx and rx timeouts, only delivers one to
    the callback, and does not overwrite an earlier error
  o logic in i2c_probe now correct
- add "vprintf()" function so that "panic()" function can be
  technically correct
- many Hymod board changes
