Changes to shell API?

[Alan Cudmore]

I recently tried to compile and run my RTEMS kernel image ( 
github.com/alanc98/rki ) on the latest git head. I was able to get past 
a configuration option change:
#define CONFIGURE_MAXIMUM_TASKS 1024
kept the system from starting, so I changed it to 128 and it comes up.

But now I do not get a shell on the console. Are there any changes in 
the shell initialization that I need to update?

I was running this on the 4.11 git head a few months ago.

Is there any single place that documents recent changes in all of the 
configuration options ?

Thanks,
Alan
