Function Documentation

bsp_start_zero()

void BSP_START_TEXT_SECTION bsp_start_zero	(	void *	begin,
		size_t	byte_count
	)

Zeros byte_count bytes starting at begin.

It wraps around in case of an address overflow. The stack will not be used. The code is position independent. It uses the data cache block zero instruction in case the data cache is enabled. There are no alignment constains for begin and byte_count.
