Gary,
Thanks for the reply, I did use grep earlier but all the statements
seem to define function HAL_STUB_PLATFORM_INIT() as hal_diag_led_on()or a
null function. It may sound like a basic 'C' question but I want to know
when statement '#ifdef HAL_STUB_PLATFORM_INIT' in the function
initHardware() is true?

Did you try looking in the sources? A quick 'grep' shows where this is
defined (for each platform):
% find hal/sh -type f | xargs fgrep "HAL_STUB_PLATFORM_INIT("
