[PATCH u-boot-marvell 03/13] tools: kwboot: Reserve enough space for patching kwbimage in memory

From: Pali Rohár <pali@kernel.org>

SPI image header and data parts do not have to be aligned to 128 byte
xmodem block size. So reserve additional memory for aligning header part
and additional memory for aligning data part.
