6 This file describes support for LynuxWorks KDI within U-Boot. Support
7 is enabled by defining CONFIG_LYNXKDI.
10 LYNXOS AND BLUECAT SUPPORTED
11 ============================
12 Both LynxOS and BlueCat linux KDIs are supported. The implementation
13 automatically detects which is being booted. When you use mkimage
14 you should specify "lynxos" for both (see target-specific notes).
17 SUPPORTED ARCHITECTURE/TARGETS
18 ==============================
19 The following targets have been tested:
26 include/lynxkdi.h -defines a simple struct passed to a kdi.
27 common/lynxkdi.c -implements the call to the kdi.
28 common/cmd_bootm.c -top-level command implementation ("bootm").
31 ====================================================================
33 ====================================================================
37 The default LynxOS and BlueCat implementations require some
38 modifications to the config file.
40 Edit include/configs/MPC8260ADS.h to use the following:
42 #define CONFIG_SYS_IMMR 0xFA200000
43 #define CONFIG_SYS_BCSR 0xFA100000
44 #define CONFIG_SYS_BR1_PRELIM 0xFA101801
46 When creating a LynxOS or BlueCat u-boot image using mkimage,
47 you must specify the following:
49 Both: -A ppc -O lynxos -T kernel -C none
50 LynxOS: -a 0x00004000 -e 0x00004020
51 BlueCat: -a 0x00500000 -e 0x00507000
53 To pass the MAC address to BlueCat you should define the
54 "fcc2_ether_addr" parameter in the "bootargs" environment
57 ==> setenv bootargs fcc2_ether_addr=00:11:22:33:44:55:66
