This patch adds the CONFIG_SPL_IMAGE option to select the SPL image that shall be used to generate the combined SPL + U-Boot image. The default value is the current value "spl/u-boot-spl.bin".
This patch also sets CONFIG_SPL_IMAGE to "spl/boot.bin" for AT91 targets which use SPL NAND support (boot from NAND). For these build targets the combined image "u-boot-with-spl.bin" is now automatically generated and can be programmed into NAND as one single image (vs. SPL image and U-Boot as 2 separate images).
