This driver is safe to use in SPL without relocation. Denying DM_FLAG_PRE_RELOC prevents its usability for verifying the main U-Boot or other artifacts from the SPL unless needless enabling the full driver set (SPL_OF_PLATDATA).

Applied to u-boot/master, thanks!
With this patch applied pine64-lts_defconfig with CONFIG_RSA=y does not boot anymore. See the output below. So something is wrong with this driver.
Do you have an idea how to analyze what is wrong? Unfortunately there is no DEBUG_UART available on the Pine A64 LTS board.
Best regards
