1 | BEDBUG Support for U-Boot | |
2 | -------------------------- | |
3 | ||
4 | These changes implement the bedbug (emBEDded deBUGger) debugger in U-Boot. | |
5 | A specific implementation is made for the AMCC 405 processor but other flavors | |
6 | can be easily implemented. | |
7 | ||
8 | ##################### | |
9 | ### Modifications ### | |
10 | ##################### | |
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 | ./arch/powerpc/cpu/ppc4xx/Makefile | |
22 | Added bedbug_405.c to the Makefile. | |
23 | ||
24 | ./arch/powerpc/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 | ./arch/powerpc/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/ppc_asm.tmpl | |
35 | Added code to handle critical exceptions | |
36 | ||

38 | ### New Stuff ### | |
39 | ################# | |

41 | ./include/bedbug/ppc.h | |
42 | ./include/bedbug/regs.h | |
43 | ./include/bedbug/bedbug.h | |
44 | ./include/bedbug/elf.h [obsoleted by new include/elf.h] | |
45 | ./include/bedbug/tables.h | |
46 | ./include/cmd_bedbug.h | |
47 | ./common/cmd_bedbug.c | |
48 | ./common/bedbug.c | |
49 | Bedbug library includes code for assembling and disassembling | |
50 | PowerPC instructions to/from memory as well as handling | |
51 | hardware breakpoints and stepping through code. These | |
52 | routines are common to all PowerPC processors. | |
53 | ||
54 | ./arch/powerpc/cpu/ppc4xx/bedbug_405.c | |
55 | AMCC PPC405 specific debugger routines. | |
56 | ||
57 | ||
58 | Bedbug support for the MPC860 | |
59 | ----------------------------- | |
60 | ||
61 | Changes: | |
62 | ||
63 | common/cmd_bedbug.c | |
64 | Added call to initialize 860 debugger. | |
65 | ||
66 | arch/powerpc/cpu/mpc8xx/Makefile | |
67 | Added new file "bedbug_860.c" to the makefile | |
68 | ||
69 | arch/powerpc/cpu/mpc8xx/start.S | |
70 | Added handler for InstructionBreakpoint (0xfd00) | |
71 | ||
72 | arch/powerpc/cpu/mpc8xx/traps.c | |
73 | Added new routine DebugException() | |
