void NutBoardInit

(

void

)

Early LISA hardware initialization. Especialy SD-RAM.

Early AT91SAM7X-EK hardware initialization.

This routine is called during system initalization.

void NutIdleInit

(

void

)

Extended system initialisation. Add sdram memory to the available memory.

Late Gameboy Advance hardware initialization.

This routine is called during system initialisation right before the idle thread is created. We will use it to add the SDRAM memory space to out heap.
