Downloading and Running a Program->Scripts to Initialise SDRAM

The script to initialise chips which use SDRAM are slightly more complicated.  The SDRAM must be initialised in a particular sequence and the SDRAM must be written to in order to initiate a precharge and to set it's
on-board mode.  This is a typical script for a target board with SDRAM:
    
[VARIANT=5307A]
; This configuration script was created on 15 May 2000 13:46:47
; using information gathered from the target hardware.
MBAR=0X10000001
DCR=0X8230
; Synchronous DRAM banks must be initialised in stages
; First set the address control register with refresh disabled
; Second set the address control register with precharge enabled
; Then write into the DRAM to initiate the precharge
; Then set the refresh bit
; Then wait (do something else) while the required refreshes occur
