PPC: remove dead boards (AMX860, c2mon, ETX094, IAD210, LANTEC, SCM)

Browse Source 
These boards have long reached EOL, and there has been no indication
of any active users of such hardware for years.  Get rid of the dead
weight.

* FUNCTION NAME: atmUtpInit

* DESCRIPTION:
*
* This function initializes the ATM interface for
*
* - UTOPIA mode
* - muxed bus
* - master operation
* - multi PHY (because of a bug in the MPC860P rev. E.0)
* - internal clock = SYSCLK / 2
*
* EXTERNAL EFFECTS:
*
* After calling this function, the MPC860ESAR UTOPIA bus is
* active and uses the following ports/pins:
*

* REMARK:
*
* The ATM parameters and data structures must be configured before
* initializing the UTOPIA port. The UTOPIA port activates immediately
* upon initialization, and if its associated data structures are not
* initialized, the CPM will lock up.

CCM/SCM-Ergaenzungen fuer U-Boot und Linux:
-------------------------------------------
Es gibt nun ein gemeinsames Kommando zum Laden der FPGAs:
=> help fpga
fpga fpga status [name] - print FPGA status
fpga reset [name] - reset FPGA
fpga load [name] addr - load FPGA configuration data
Der Name kann beim CCM-Module auch weggelassen werden.
Die Laengenangabe und damit "puma_len" ist nicht mehr
noetig:
=> fpga load puma 40600000
FPGA load PUMA: addr 40600000: (00000005)... done
Die MTD-Partitionierung kann nun mittels "bootargs" ueber-
geben werden:
=> printenv addmtd
addmtd=setenv bootargs ${bootargs}
mtdparts=0:256k(U-Boot)ro,768k(Kernel),-(Rest)\;1:-(myJFFS2)
Die Portierung auf SMC ist natuerlich noch nicht getestet.
