+Interactive DDR debugging
+===========================
+
+For DDR parameter tuning up and debugging, the interactive DDR debugging can
+be activated by saving an environment variable "ddr_interactive". The value
+doesn't matter. Once activated, U-boot prompts "FSL DDR>" before enabling DDR
+controller. The available commands can be seen by typing "help".
+
+The example flow of using interactive debugging is
+type command "compute" to calculate the parameters from the default
+type command "print" with arguments to show SPD, options, registers
+type command "edit" with arguments to change any if desired
+type command "go" to continue calculation and enable DDR controller
+type command "reset" to reset the board
+type command "recompute" to reload SPD and start over
+
+Note, check "next_step" to show the flow. For example, after edit opts, the
+next_step is STEP_ASSIGN_ADDRESSES. After editing registers, the next_step is
+STEP_PROGRAM_REGS. Upon issuing command "go", DDR controller will be enabled
+with current setting without further calculation.
+
+The detail syntax for each commands are
+
+print [c<n>] [d<n>] [spd] [dimmparms] [commonparms] [opts] [addresses] [regs]
+ c<n> - the controller number, eg. c0, c1
+ d<n> - the DIMM number, eg. d0, d1
+ spd - print SPD data
+ dimmparms - DIMM paramaters, calcualted from SPD
+ commonparms - lowest common parameters for all DIMMs
+ opts - options
+ addresses - address assignment (not implemented yet)
+ regs - controller registers
+
+edit <c#> <d#> <spd|dimmparms|commonparms|opts|addresses|regs> <element> <value>
+ c<n> - the controller number, eg. c0, c1
+ d<n> - the DIMM number, eg. d0, d1
+ spd - print SPD data
+ dimmparms - DIMM paramaters, calcualted from SPD
+ commonparms - lowest common parameters for all DIMMs
+ opts - options
+ addresses - address assignment (not implemented yet)
+ regs - controller registers
+ <element> - name of the modified element
+ byte number if the object is SPD
+ <value> - decimal or heximal (prefixed with 0x) numbers
+
+reset
+ no arguement - reset the board
+
+recompute
+ no argument - reload SPD and start over
+
+compute
+ no argument - recompute from current next_step
+
+next_step
+ no argument - show current next_step
+
+help
+ no argument - print a list of all commands
+
+go
+ no argument - program memory controller(s) and continue with U-boot
