[U-Boot] [PATCH 09/12 v2] Makefile: Add Kconfig option CONFIG_SPL_IMAGE to select the SPL binary

Stefan Roese sr at denx.de
Tue Mar 26 12:16:39 UTC 2019


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).
