 * AMI FS6377 Clock Generator configuration table
 *
 * the "fs6377_regs[]" table entries correspond to FS6377 registers
 * 0 - 15 (total of 16 bytes).
 *
 * the data is written to the FS6377 via the i2c bus using address in
 * "fs6377_addr" (address is 7 bits - R/W bit not included).
 *
 * The fs6377 has four clock outputs: A, B, C and D.
 *
 * Outputs C and D can each provide two different clock outputs C1/D1 or
 * C2/D2 depending on the state of the SEL_CD input which is connected to
 * the MPC8260 I/O port pin PA11. PA11 output (SEL_CD input) low (or 0)
 * selects C1/D1 and PA11 output (SEL_CD input) high (or 1) selects C2/D2.
 *
 * PA11 defaults to output low (or 0) in the i/o port config table above.
 *
 * Output A provides a 100MHz for the High Speed Serial chips. Output B
 * provides a 3.6864MHz clock for more accurate asynchronous serial bit
 * rates. Output C is routed to the mezzanine connector but is currently
 * unused - both C1 and C2 are set to 16MHz. Output D is used by both the
 * alt-input and display mezzanine boards for their video chips. The
 * alt-input board requires a clock of 24.576MHz and this is available on
 * D1 (PA11=SEL_CD=0). The display board requires a clock of 27MHz and this
 * is available on D2 (PA11=SEL_CD=1).
 *
 * So the default is a clock suitable for the alt-input board. PA11 is toggled
 * later in misc_init_r(), if a display board is detected.

	 *  (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
	 *
	 *  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 CONFIG_SYS_SDRAM_BASE.
