[ECOS] Scheduler Lock without Kernel

[Martin Laabs]

Hi,

I currently improve the Ethernet driver for the at91sam9 family of CPUs. 
However - Since this CPU has a cache and is using DMA for data exchange 
with the MAC I have to lock the scheduler while manipulating these memory 
structures. (This is to ensure, that the cache is coherent while doing this 
manipulations)
Since the code should run with the kernel as well without it I'd like to 
know whether it's save to call the cyg_scheduler_lock without being in 
kernel mode.
But I fear I have to write a macro that distinguish between "with kernel" 
and "hal only". Am I right? Which symbol is best to distinguish between 
thees two possibilities?

Thank you,
  Martin laabs
