[commit] r873 - trunk/openbios-devel/arch/sparc64

New Revision: 873

Log:
Increase IMAGE_STACK_SIZE to 16K from 8K.

The existing 8K stack used when switching context to run the executable payload was not enough. Increasing the stack to 16K 
solves the issue, preventing the payload from clobbering memory within OpenBIOS as it runs.
