Add support for Motorola MPC8266ADS board

* Patch by Kyle Harris, 19 Feb 2003:
  patches for the Intel lubbock board:
  memsetup.S - general cleanup (based on Robert's csb226 code)
  flash.c - overhaul, actually works now
  lubbock.c - fix init funcs to return proper value

* Patch by Kenneth Johansson, 26 Feb 2003:
  - Fixed off by one in RFTA calculation.
  - No need to abort when LDF is lower than we can program it's only
    minimum timing so clamp it to what we can do.
  - Takes function pointer to function for reading the spd_nvram. Usefull
    for faking data or hardcode a module without the nvram.
  - fix other user for above change
  - fix some comments.

* Patches by Brian Waite, 26 Feb 2003:
  - fix port for evb64260 board
  - fix PCI for evb64260 board
  - fix PCI scan

* Patch by Reinhard Meyer, 1 Mar 2003:
  Add support for EMK TOP860 Module

* Patch by Yuli Barcohen, 02 Mar 2003:
  Add SPD EEPROM support for MPC8260ADS board

* Quote from 8260 UM (10.4.2 SDRAM Power-On Initialization, 10-35):
*
* "At system reset, initialization software must set up the
* programmable parameters in the memory controller banks registers
* (ORx, BRx, P/LSDMR). After all memory parameters are configured,
* system software should execute the following initialization sequence
* for each SDRAM device.
*
* 1. Issue a PRECHARGE-ALL-BANKS command
* 2. Issue eight CBR REFRESH commands
* 3. Issue a MODE-SET command to initialize the mode register
*
* Quote from Micron MT48LC8M16A2 data sheet:
*
* "...the SDRAM requires a 100uS delay prior to issuing any
* command other than a COMMAND INHIBIT or NOP. Starting at some
* point during this 100uS period and continuing at least through
* the end of this period, COMMAND INHIBIT or NOP commands should
* be applied."
*
* "Once the 100uS delay has been satisfied with at least one COMMAND
* INHIBIT or NOP command having been applied, a /PRECHARGE command/
* should be applied. All banks must then be precharged, thereby
* placing the device in the all banks idle state."
*
* "Once in the idle state, /two/ AUTO REFRESH cycles must be
* performed. After the AUTO REFRESH cycles are complete, the
* SDRAM is ready for mode register programming."
*
* (/emphasis/ mine, gvb)
*
* The way I interpret this, Micron start up sequence is:
* 1. Issue a PRECHARGE-BANK command (initial precharge)
* 2. Issue a PRECHARGE-ALL-BANKS command ("all banks ... precharged")
* 3. Issue two (presumably, doing eight is OK) CBR REFRESH commands
* 4. Issue a MODE-SET command to initialize the mode register
*
* --------
*
* The initial commands are executed by setting P/LSDMR[OP] and
* accessing the SDRAM with a single-byte transaction."
*
* The appropriate BRx/ORx registers have already been set when we
* get here. The SDRAM can be accessed at the address CFG_SDRAM_BASE.
