 (*) Although the hardware can be configured with memory controller
 | 
						|
 interleaving using "2x2" rank interleaving, it only interleaves {CS0+CS1}
 | 
						|
 from each controller. {CS2+CS3} on each controller are only rank
 | 
						|
 interleaved on that controller.
 | 
						|
 | 
						|
 For memory controller interleaving, identical DIMMs are suggested. Software
 | 
						|
 doesn't check the size or organization of interleaved DIMMs.
 | 
						|
 | 
						|
The ways to configure the ddr interleaving mode
 | 
						|
==============================================
 | 
						|
1. In board header file(e.g.MPC8572DS.h), add default interleaving setting
 | 
						|
   under "CONFIG_EXTRA_ENV_SETTINGS", like:
 | 
						|
	#define CONFIG_EXTRA_ENV_SETTINGS				\
 | 
						|
	 "hwconfig=fsl_ddr:ctlr_intlv=bank"			\
 | 
						|
	 ......
 | 
						|
 | 
						|
2. Run U-Boot "setenv" command to configure the memory interleaving mode.
 | 
						|
   Either numerical or string value is accepted.
 | 
						|
 | 
						|
  # disable memory controller interleaving
 | 
						|
  setenv hwconfig "fsl_ddr:ctlr_intlv=null"
 | 
						|
 | 
						|
  # cacheline interleaving
 | 
						|
  setenv hwconfig "fsl_ddr:ctlr_intlv=cacheline"
 | 
						|
 | 
						|
  # page interleaving
 | 
						|
  setenv hwconfig "fsl_ddr:ctlr_intlv=page"
 | 
						|
 | 
						|
  # bank interleaving
 | 
						|
  setenv hwconfig "fsl_ddr:ctlr_intlv=bank"
 | 
						|
 | 
						|
  # superbank
 | 
						|
  setenv hwconfig "fsl_ddr:ctlr_intlv=superbank"
 | 
						|
 | 
						|
  # 1KB 3-way interleaving
 | 
						|
  setenv hwconfig "fsl_ddr:ctlr_intlv=3way_1KB"
 | 
						|
 | 
						|
  # 4KB 3-way interleaving
 | 
						|
  setenv hwconfig "fsl_ddr:ctlr_intlv=3way_4KB"
 | 
						|
 | 
						|
  # 8KB 3-way interleaving
 | 
						|
  setenv hwconfig "fsl_ddr:ctlr_intlv=3way_8KB"
 | 
						|
 | 
						|
  # disable bank (chip-select) interleaving
 | 
						|
  setenv hwconfig "fsl_ddr:bank_intlv=null"
 | 
						|
 | 
						|
  # bank(chip-select) interleaving cs0+cs1
 | 
						|
  setenv hwconfig "fsl_ddr:bank_intlv=cs0_cs1"
 | 
						|
 | 
						|
  # bank(chip-select) interleaving cs2+cs3
 | 
						|
  setenv hwconfig "fsl_ddr:bank_intlv=cs2_cs3"
 | 
						|
 | 
						|
  # bank(chip-select) interleaving (cs0+cs1) and (cs2+cs3)  (2x2)
 | 
						|
  setenv hwconfig "fsl_ddr:bank_intlv=cs0_cs1_and_cs2_cs3"
 | 
						|
 | 
						|
  # bank(chip-select) interleaving (cs0+cs1+cs2+cs3) (4x1)
 | 
						|
  setenv hwconfig "fsl_ddr:bank_intlv=cs0_cs1_cs2_cs3"
 | 
						|
 | 
						|
  # bank(chip-select) interleaving (auto)
 | 
						|
  setenv hwconfig "fsl_ddr:bank_intlv=auto"
 | 
						|
  This auto mode only select from cs0_cs1_cs2_cs3, cs0_cs1, null dependings
 | 
						|
  on DIMMs.
 | 
						|
 | 
						|
Memory controller address hashing
 | 
						|
==================================
 | 
						|
If the DDR controller supports address hashing, it can be enabled by hwconfig.
 | 
						|
 | 
						|
Syntax is:
 | 
						|
hwconfig=fsl_ddr:addr_hash=true
 | 
						|
 | 
						|
Memory controller ECC on/off
 | 
						|
============================
 | 
						|
If ECC is enabled in board configuratoin file, i.e. #define CONFIG_DDR_ECC,
 | 
						|
ECC can be turned on/off by hwconfig.
 | 
						|
 | 
						|
Syntax is
 | 
						|
hwconfig=fsl_ddr:ecc=off
 | 
						|
 | 
						|
 | 
						|
Memory address parity on/off
 | 
						|
============================
 | 
						|
address parity can be turned on/off by hwconfig.
 | 
						|
Syntax is:
 | 
						|
hwconfig=fsl_ddr:parity=on
 | 
						|
 | 
						|
 | 
						|
Memory testing options for mpc85xx
 | 
						|
==================================
 | 
						|
1. Memory test can be done once U-Boot prompt comes up using mtest, or
 | 
						|
2. Memory test can be done with Power-On-Self-Test function, activated at
 | 
						|
   compile time.
 | 
						|
 | 
						|
   In order to enable the POST memory test, CONFIG_POST needs to be
 | 
						|
   defined in board configuraiton header file. By default, POST memory test
 | 
						|
   performs a fast test. A slow test can be enabled by changing the flag at
 | 
						|
   compiling time. To test memory bigger than 2GB, 36BIT support is needed.
 | 
						|
   Memory is tested within a 2GB window. TLBs are used to map the virtual 2GB
 | 
						|
   window to physical address so that all physical memory can be tested.
 | 
						|
 | 
						|
Combination of hwconfig
 | 
						|
=======================
 | 
						|
Hwconfig can be combined with multiple parameters, for example, on a supported
 | 
						|
platform
 | 
						|
 | 
						|
hwconfig=fsl_ddr:addr_hash=true,ctlr_intlv=cacheline,bank_intlv=cs0_cs1_cs2_cs3,ecc=on
 | 
						|
 | 
						|
 | 
						|
Table for dynamic ODT for DDR3
 | 
						|
==============================
 | 
						|
For single-slot system with quad-rank DIMM and dual-slot system, dynamic ODT may
 | 
						|
be needed, depending on the configuration. The numbers in the following tables are
 | 
						|
in Ohms.
 | 
						|
 | 
						|

Interactive DDR debugging
 | 
						|
===========================
 | 
						|
 | 
						|
For DDR parameter tuning up and debugging, the interactive DDR debugger can
 | 
						|
be activated by setting the environment variable "ddr_interactive" to any
 | 
						|
value.  (The value of ddr_interactive may have a meaning in the future, but,
 | 
						|
for now, the presence of the variable will cause the debugger to run.)  Once
 | 
						|
activated, U-Boot will show the prompt "FSL DDR>" before enabling the DDR
 | 
						|
controller.  The available commands are printed by typing "help".
 | 
						|
 | 
						|
Another way to enter the interactive DDR debugger without setting the
 | 
						|
environment variable is to send the 'd' character early during the boot
 | 
						|
process.  To save booting time, no additional delay is added, so the window
 | 
						|
to send the key press is very short -- basically, it is the time before the
 | 
						|
memory controller code starts to run.  For example, when rebooting from
 | 
						|
within U-Boot, the user must press 'd' IMMEDIATELY after hitting enter to
 | 
						|
initiate a 'reset' command.  In case of power on/reset, the user can hold
 | 
						|
down the 'd' key while applying power or hitting the board's reset button.
 | 
						|
 | 
						|
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 "copy" with arguments to copy controller/dimm settings
 | 
						|
type command "go" to continue calculation and enable DDR controller
 | 
						|
 | 
						|
Additional commands to restart the debugging are:
 | 
						|
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", the debugger will program the
 | 
						|
DDR controller with the current setting without further calculation and then
 | 
						|
exit to resume the booting of the machine.
 | 
						|
 | 
						|
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 parameters, calculated 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 parameters, calculated 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
 | 
						|
 | 
						|
copy <src c#> <src d#> <spd|dimmparms|commonparms|opts|addresses|regs> <dst c#> <dst d#>
 | 
						|
	same as for "edit" command
 | 
						|
	DIMM numbers ignored for commonparms, opts, and regs
 | 
						|
 | 
						|
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
