* Patch by Scott McNutt, 21 Jul 2003:
Add support for LynuxWorks Kernel Downloadable Images (KDIs). Both LynxOS and BlueCat linux KDIs are supported. * Patch by Richard Woodruff, 25 Jul 2003: use more reliable reset for OMAP/925T * Patch by Nye Liu, 25 Jul 2003: fix typo in mpc8xx.h * Patch by Richard Woodruff, 24 Jul 2003: Fixes for cmd_nand.c: - 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. - Fixed nand.h's ECCPOS. A conflict existed with POS5 and badblock for non-JFFS2. - Switched default ECC to be JFFS2.

+ 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
