- * GDB assumes that we're a user process being debugged, so
- * it will send us an SWI command to write into memory as the
- * debug trap. When an SWI occurs, the next instruction addr is
- * placed into R14_svc before jumping to the vector trap.
- * This doesn't work for kernel debugging as we are already in SVC
- * we would loose the kernel's LR, which is a bad thing. This
- * is bad thing.
- *
- * By doing this as an undefined instruction trap, we force a mode
- * switch from SVC to UND mode, allowing us to save full kernel state.
- *
- * We also define a KGDB_COMPILED_BREAK which can be used to compile
- * in breakpoints. This is important for things like sysrq-G and for
- * the initial breakpoint from trap_init().
- *
- * Note to ARM HW designers: Add real trap support like SH && PPC to
- * make our lives much much simpler. :)

- * From Kevin Hilman:
- *
- * gdb is expecting the following registers layout.
- *
- * r0-r15: 1 long word each
- * f0-f7: unused, 3 long words each !!
- * fps: unused, 1 long word
- * cpsr: 1 long word
- *
- * Even though f0-f7 and fps are not used, they need to be
- * present in the registers sent for correct processing in
- * the host-side gdb.
- *
- * In particular, it is crucial that CPSR is in the right place,
- * otherwise gdb will not be able to correctly interpret stepping over
- * conditional branches.
