* Patch by Denis Peter, 8 Dec 2003

  - add support for the PATI board (MPC555)
  - add SPI support for the MPC5xx

* Patch by Anders Larsen, 08 Dec 2003:
  add configuration options CONFIG_SERIAL_TAG and CONFIG_REVISION_TAG
  to pass ATAG_SERIAL and ATAG_REVISION, resp., to the ARM target;
  cleanup some redundand #defines

+ * Bits for the SDRAM controller
+ * -----------------------------
+ *
+ * CAL:	CAS Latency. If cleared to 0 (default) the SDRAM controller asserts TA# on
+ *	the 2nd Clock after ACTIVE command (CAS Latency = 2). If set to 1 the SDRAM
+ *	controller asserts TA# on the 3rd Clock after ACTIVE command (CAS Latency = 3).
+ * RCD:	RCD ACTIVE to READ or WRITE Delay (Ras to Cas Delay). If cleared 0 (default)
+ *	tRCD of the SDRAM must equal or less 25ns. If set to 1 tRCD must be equal or less 50ns.
+ * WREC:Write Recovery. If cleared 0 (default) tWR of the SDRAM must equal or less 25ns.
+ *	If set to 1 tWR must be equal or less 50ns.
+ * RP:	Precharge Command Time. If cleared 0 (default) tRP of the SDRAM must equal or less
+ *	25ns. If set to 1 tRP must be equal or less 50ns.
+ * RC:	Auto Refresh to Active Time. If cleared 0 (default) tRC of the SDRAM must equal
+ *	or less 75ns. If set to 1 tRC must be equal or less 100ns.
+ * LMR:	Bit to set the Mode Register of the SDRAM. If set, the next access to the SDRAM
+ *	is the Load Mode Register Command.
+ * IIP:	Init in progress. Set to 1 for starting the init sequence
+ *	(Precharge All). As long this bit is set, the Precharge All is still in progress.
+ *	After command has completed, wait at least for 8 refresh (200usec) before proceed.
