Rename the bl31_entry() function with 'spl_' prefix and add one parameter for bl31 entry address since we can get it from spl_image header.
Just as a heads-up, I also have a patch in my queue (i.e. to submit this week) that integrates as IH_OS_ARM_TRUSTED_FIRMWARE and adds the option to pass a pointer to the FDT as a platform-parameter.
I’ll copy you, so we can then figure out how to best merge your and my changes and apply those at the same time.
Regards, Philipp.
