Trimedia

The basic idea is the same as that of x86. However in case of trimedia, the return addresse is stored in register 2 and the arguments are passed through registers 5 & 6.

void CPU_Context_Initialize(struct reg_context *the_context,void *stack_base,
                    oskit_u32_t stack_size,                         
                    void *(*entry_point)(void *,void *),
                    void *(*thread_fun)(void *),
                    void *thread_arg)
{
  oskit_u32_t stack;
  stack=((int)stack_base)+stack_size;
