redboot configuration bug


Hello,

I am building a RAM version of redboot, and I want to disable the following option:
CYGSEM_HAL_VIRTUAL_VECTOR_CLAIM_COMMS.
But this *forces* CYGNUM_HAL_VIRTUAL_VECTOR_DEBUG_CHANNEL to become inactive, so it is undeclared.
And therefore redboot/../main.c fails to compile on line 270:
void
cyg_start(void)
{
...
CYGACC_CALL_IF_SET_CONSOLE_COMM(CYGNUM_HAL_VIRTUAL_VECTOR_DEBUG_CHANNEL);


The CDL rationale is correct:
CYGNUM_HAL_VIRTUAL_VECTOR_DEBUG_CHANNEL should only be modifiable if CYGPRI_HAL_VIRTUAL_VECTOR_DEBUG_CHANNEL_CONFIGURABLE=1, and this only makes sense if CYGSEM_HAL_VIRTUAL_VECTOR_CLAIM_COMMS=1.


So the redboot source code should be changed, agree?

line 270 should be replace by something like this:
#ifdef CYGNUM_HAL_VIRTUAL_VECTOR_DEBUG_CHANNEL
CYGACC_CALL_IF_SET_CONSOLE_COMM(CYGNUM_HAL_VIRTUAL_VECTOR_DEBUG_CHANNEL);
#else
CYGACC_CALL_IF_SET_CONSOLE_COMM(READ_VVT(VVT_DEBUG_CHANNEL));
#endif


Of course READ_VVT is not the correct function/macro. Does anybody know it?

Kind regards,
Juergen
