int jt_atmelflashGetInfo	(	uint32_t	base_address,
		struct sector **	sector_info
	)

Try to get the Flash info and create a new sector_info if possible. (32-Bit access)
(Embedded flash of AT91SAM7 machines)

Parameters:

	base_address	flash base address
	sector_info	pointer to target for new sector_info

Returns:

number of flash chips per 32-bit bus (0=not found; 1=one flash)
