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 | ||
| a47a12be | 21 | ./arch/powerpc/cpu/ppc4xx/Makefile |
| e2211743 WD |
22 | Added bedbug_405.c to the Makefile. |
| 23 | ||
| a47a12be | 24 | ./arch/powerpc/cpu/ppc4xx/start.S |
| e2211743 WD |
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 | ||
| a47a12be | 29 | ./arch/powerpc/cpu/ppc4xx/traps.c |
| e2211743 WD |
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 | ||
| e2211743 WD |
34 | ./include/ppc_asm.tmpl |
| 35 | Added code to handle critical exceptions | |

| 51 | hardware breakpoints and stepping through code. These | |
| 52 | routines are common to all PowerPC processors. | |
