.img is not required by SPL. in OMAP SPL code in uboot, the name u-boot.img
is hardcoded. When actually loading the file (see
http://git.denx.de/?p=u-boot.git;a=blob;f=arch/arm/cpu/armv7/omap-common/spl.c;h=9c1f7e3eda6ce2c405b6c4aa123436036b0f2209;hb=master#l68)
we first check if the u-boot.img is using a mkimage file format, otherwise
we assume it's a raw .bin format. but the filename is still hardcoded, so
we can have platform with SPL but with u-boot.bin
