Detailed Description

ARM system low level start.

Function Documentation

bsp_start_hook_0()

void bsp_start_hook_0

(

void

)

Start entry hook 0.

This hook will be called from the start entry code after all modes and stack pointers are initialized but before the copying of the exception vectors.

bsp_start_hook_1()

void bsp_start_hook_1

(

void

)

Start entry hook 1.

This hook will be called from the start entry code after copying of the exception vectors but before the call to boot_card().

bsp_start_memcpy()

void bsp_start_memcpy	(	int *	dest,
		const int *	src,
		size_t	n )

Similar to standard memcpy().

The memory areas must be word aligned. Copy code will be executed from the stack. If dest equals src nothing will be copied.
