tools: kwbimage: Support u-boot.img padding to CONFIG_SYS_SPI_U_BOOT_OFFS
This is used on the AXP boards, to pad u-boot.img to the desired offset in SPI flash (only this boot target supported right now). This offset is used by the SPL then to load u-boot.img into SDRAM and execute it there. Signed-off-by: Stefan Roese <sr@denx.de> Reviewed-by: Luka Perkov <luka.perkov@sartura.hr>
