void __iowrite32_copy	(	void __iomem *	to,
		const void *	from,
		size_t	count
	)

void __iowrite64_copy	(	void __iomem *	to,
		const void *	from,
		size_t	count
	)

int check_signature	(	const volatile void __iomem *	io_addr,
		const unsigned char *	signature,
		int	length
	)

check_signature - find BIOS signatures : mmio address to check : signature block : length of signature

Perform a signature comparison with the mmio address io_addr. This address should have been obtained by ioremap. Returns 1 on a match.

devm_ioremap - Managed ioremap() : Generic device to remap IO address for : BUS offset to map : Size of map

Managed ioremap(). Map is automatically unmapped on driver detach.
