1 | BEDBUG Support for U-Boot |
| 2 | -------------------------- | |
| 3 | ||
| 4 | These changes implement the bedbug (emBEDded deBUGger) debugger in U-Boot. | |
| 0c8721a4 | 5 | A specific implementation is made for the AMCC 405 processor but other flavors |
| e2211743 WD |
6 | can be easily implemented. |

| 11 | ||
| 12 | ./common/Makefile | |
| 13 | Included cmd_bedbug.c and bedbug.c in the Makefile. | |
| 14 | ||
| 15 | ./common/command.c | |
| 16 | Added bedbug commands to command table. | |
| 17 | ||
| 18 | ./common/board.c | |
| 19 | Added call to initialize debugger on startup. | |
| 20 | ||
| 21 | ./cpu/ppc4xx/Makefile | |
| 22 | Added bedbug_405.c to the Makefile. | |
| 23 | ||
| 24 | ./cpu/ppc4xx/start.S | |
| 25 | Added code to handle the debug exception (0x2000) on the 405. | |
| 26 | Also added code to handle critical exceptions since the debug | |
| 27 | is treated as critical on the 405. | |
| 28 | ||
| 29 | ./cpu/ppc4xx/traps.c | |
| 30 | Added more detailed output for the program exception to tell | |
| 31 | if it is an illegal instruction, privileged instruction or | |
| 32 | a trap. Also added debug trap handler. | |
| 33 | ||
| 34 | ./include/cmd_confdefs.h | |
| 35 | Added definition of CFG_CMD_BEDBUG. | |
| 36 | ||
| 37 | ./include/config_WALNUT405.h | |
| 38 | Added CFG_CMD_BEDBUG to the CONFIG_COMMANDS for the WALNUT. | |
| 39 | ||
| 40 | ./include/ppc_asm.tmpl | |
| 41 | Added code to handle critical exceptions | |

| 55 | Bedbug library includes code for assembling and disassembling | |
| 56 | PowerPC instructions to/from memory as well as handling | |
| 57 | hardware breakpoints and stepping through code. These | |
| 58 | routines are common to all PowerPC processors. | |
