* include/plf_intr.h: Defined CYGNUM_HAL_INTERRUPT_RTC to
counter/compare register interrupt. Added implementations of
HAL_INTERRUPT_MASK, HAL_INTERRUPT_UNMASK, and
HAL_INTERRUPT_ACKNOWLEDGE that will work in eCos rather than just
RedBoot.
* src/plf_misc.c (hal_platform_init): Changed spelling of eCos for
the LED to match the official typography.
