Change CONFIG_SPL_PAD_TO from a link address to an image offset since this is more handy and closer to the purpose of this config.
Automatically define CONFIG_SPL_PAD_TO to CONFIG_SPL_MAX_SIZE (or 0 without CONFIG_SPL_MAX_SIZE).
Test that CONFIG_SPL_PAD_TO >= CONFIG_SPL_MAX_SIZE if CONFIG_SPL_PAD_TO is non-zero.
Signed-off-by: Benoît Thébaudeau benoit.thebaudeau@advansee.com --- Changes in v8: - Rebase on latest u-boot-imx/master. - Use CONFIG_SPL_PAD_TO instead of CONFIG_SPL_MAX_SIZE for u-boot-with-spl.bin padding.
Changes in v7: - Use u-boot-spl.bin instead of u-boot-spl in order to avoid having to use --change-addresses.
Changes in v6: - Fix size passed to --pad-to thanks to --change-addresses.
Changes in v5: None Changes in v4: - New patch.
Changes in v3: None Changes in v2: None
