[PATCH u-boot-marvell 20/29] tools: kwboot: Patch source address in image header

[Marek Behún]

From: Pali Rohár <pali at kernel.org>

Some image types have source address in non-bytes unit; for example for
SATA images, it is in 512 B units.

We need to multiply by unit size when patching image type to UART.
