[U-Boot] [PATCH] spl, Makefile: Take external offset into account for fit images
When building a FIT image for SPL to load also take into account the configured external offset. This allows the SPL to load the u-boot FIT image correctly when configuring SECURE_BOOT on i.mx6 is enabled (with CONFIG_FIT_EXTERNAL_OFFSET=0x3000).
Note this doesn't allow secure booting; but it does allow an unsigned SPL/u-boot with secure boot support eanbled to boot on open device.

Does this change behavior on systems which don't use CONFIG_FIT_EXTERNAL_OFFSET ?

Nope; in that case the default CONFIG_FIT_EXTERNAL_OFFSET is 0x0, which gets essentially ignored if passed as a argument to -p
