  - Fixed null dereferece which could result in incorrect ECC values.
  - Added support for devices with no Ready/Busy signal hooked up.
  - Added OMAP1510 read/write protect handling.

LYNX KDI SUPPORT
Last Update: July 20, 2003
=======================================================================
This file describes support for LynuxWorks KDI within U-Boot. Support
is enabled by defining CONFIG_LYNXKDI.
LYNXOS AND BLUECAT SUPPORTED
============================
Both LynxOS and BlueCat linux KDIs are supported. The implementation
automatically detects which is being booted. When you use mkimage
you should specify "lynxos" for both (see target-specific notes).
SUPPORTED ARCHITECTURE/TARGETS
==============================
The following targets have been tested:
-PowerPC MPC8260ADS
FILES TO LOOK AT
================
include/lynxkdi.h -defines a simple struct passed to a kdi.
common/lynxkdi.c -implements the call to the kdi.
common/cmd_bootm.c -top-level command implementation ("bootm").
====================================================================
TARGET SPECIFIC NOTES
====================================================================
MPC8260ADS
===========
The default LynxOS and BlueCat implementations require some
modifications to the config file.
Edit include/configs/MPC8260ADS.h to use the following:
#define CFG_IMMR 0xFA200000
#define CFG_BCSR 0xFA100000
#define CFG_BR1_PRELIM 0xFA101801
When creating a LynxOS or BlueCat u-boot image using mkimage,
you must specify the following:
Both: -A ppc -O lynxos -T kernel -C none
LynxOS: -a 0x00004000 -e 0x00004020
BlueCat: -a 0x00500000 -e 0x00507000
To pass the MAC address to BlueCat you should define the
"fcc2_ether_addr" parameter in the "bootargs" environment
variable. E.g.:
==> setenv bootargs fcc2_ether_addr=00:11:22:33:44:55:66
