main_first_hart does not use provided HLS

[plwalsh]

Why does main_first_hart() take in a pointer to the HLS from the caller, but then overwrite its value to be hard-coded to the HLS for hart0?

platform/mpfs_hal/startup_gcc/system_startup.c

Lines 102 to 103 in 8af073c

	stack_top = (ptrdiff_t)((uint8_t*)&__stack_top_h0$);
	hls = (HLS_DATA*)(stack_top - HLS_DEBUG_AREA_SIZE);

That HLS pointer for hart0 then gets passed into main_other_hart() to kick off the hart entry-point function, even if the specified "first hart" is not hart0.

And similarly for main_first_hart_app(), the HLS is passed in, but then overwritten to be hard-coded to the HLS for hart1. And that value is then passed into main_other_hart():

platform/mpfs_hal/startup_gcc/system_startup.c

Lines 302 to 305 in 8af073c

	stack_top = (ptrdiff_t)((uint8_t*)&__stack_top_h1$);
	hls = (HLS_DATA*)(stack_top - HLS_DEBUG_AREA_SIZE);
	hls->in_wfi_indicator = HLS_MAIN_HART_FIN_INIT;
	(void)main_other_hart(hls);
