Changes since U-Boot 1.1.4:
======================================================================
+* Add command for handling DDR ECC registers on MPC8349EE MDS board.
+
+* Fix DDR ECC bit definitions for MPC83xx.
+
+* Add initial support for MPC8349E MDS board.
+
+* Add support for ECC DDR initialization on MPC83xx.
+
+* Add DMA support for MPC83xx.
+
+* Add sync in do_reset() routine for MPC83xx after RPR register
+ was written to. It is need on some targets when BAT translation
+ is enabled.
+
+* Add bit definitions for MPC83xx DDR controller registers.
+
+* Add Dcbz(), Dcbi() and Dcbf() routines for MPC83xx.
+
+* Correct shift offsets in icache_status and dcache_status for MPC83xx.
+
+* Add support for DS1374 RTC chip.
+
* Add support for Lite5200B board.

+Overview
+========
+
+The overall usage pattern for ECC diagnostic commands is the following:
+
+ * (injecting errors is initially disabled)
+
+ * define inject mask (which tells the DDR controller what type of errors
+ we'll be injecting: single/multiple bit etc.)
+
+ * enable injecting errors - from now on the controller injects errors as
+ indicated in the inject mask
+
+IMPORTANT NOTICE: enabling injecting multiple-bit errors is potentially
+dangerous as such errors are NOT corrected by the controller. Therefore caution
+should be taken when enabling the injection of multiple-bit errors: it is only
+safe when used on a carefully selected memory area and used under control of
+the 'ecc test' command (see example 'Injecting Multiple-Bit Errors' below). In
+particular, when you simply set the multiple-bit errors in inject mask and
+enable injection, U-Boot is very likely to hang quickly as the errors will be
+injected when it accesses its code, data etc.
+
+
+Use cases for DDR 'ecc' command:
+================================
+
+Before executing particular tests reset target board or clear status registers:
+
+=> ecc captureclear
+=> ecc errdetectclr all
+=> ecc sbecnt 0
+
+
+Injecting Single-Bit Errors
+---------------------------
+
+1. Set 1 bit in Data Path Error Inject Mask
+
+=> ecc injectdatahi 1
+
+2. Run test over some memory region
+
+=> ecc test 200000 10
+
+3. Check ECC status
+
+=> ecc status
+...
+Memory Data Path Error Injection Mask High/Low: 00000001 00000000
+...
+Memory Single-Bit Error Management (0..255):
+ Single-Bit Error Threshold: 255
+ Single Bit Error Counter: 16
+...
+Memory Error Detect:
+ Multiple Memory Errors: 0
+ Multiple-Bit Error: 0
+ Single-Bit Error: 0
+...
+
+16 errors were generated, Single-Bit Error flag was not set as Single Bit Error
+Counter did not reach Single-Bit Error Threshold.
+
+4. Make sure used memory region got re-initialized with 0xcafecafe pattern
+
+=> md 200000
+00200000: cafecafe cafecafe cafecafe cafecafe ................
+00200010: cafecafe cafecafe cafecafe cafecafe ................

+
+
+Injecting Multiple-Bit Errors
+-----------------------------
+
+1. Set more than 1 bit in Data Path Error Inject Mask
+
+=> ecc injectdatahi 5
+
+2. Run test over some memory region
+
+=> ecc test 200000 10
+
+3. Check ECC status
+
+=> ecc status
+...
+Memory Data Path Error Injection Mask High/Low: 00000005 00000000
+...
+Memory Error Detect:
+ Multiple Memory Errors: 1
+ Multiple-Bit Error: 1
+ Single-Bit Error: 0
+...
+
+Observe that both Multiple Memory Errors and Multiple-Bit Error flags are set.
+
+4. Make sure used memory region got re-initialized with 0xcafecafe pattern
+
+=> md 200000
+00200000: cafecafe cafecafe cafecafe cafecafe ................
+00200010: cafecafe cafecafe cafecafe cafecafe ................
+00200020: cafecafe cafecafe cafecafe cafecafe ................

+00200080: deadbeef deadbeef deadbeef deadbeef ................
+00200090: deadbeef deadbeef deadbeef deadbeef ................
+
+
+Test Single-Bit Error Counter and Threshold
+-------------------------------------------
+
+1. Set 1 bit in Data Path Error Inject Mask
+
+=> ecc injectdatahi 1
+
+2. Enable error injection
+
+=> ecc inject en
+
+3. Let u-boot run for a with Single-Bit error injection enabled
+
+4. Disable error injection
+
+=> ecc inject dis
+
+4. Check status
+
+=> ecc status
+
+...
+Memory Single-Bit Error Management (0..255):
+ Single-Bit Error Threshold: 255
+ Single Bit Error Counter: 60
+
+Memory Error Detect:
+ Multiple Memory Errors: 1
+ Multiple-Bit Error: 0
+ Single-Bit Error: 1
+...
+
+Observe that Single-Bit Error is 'on' which means that Single-Bit Error Counter
+reached Single-Bit Error Threshold. Multiple Memory Errors bit is also 'on', that
+is Counter reached Threshold more than one time (it wraps back after reaching
+Threshold).
