Hello! I have tested it without dm-pre-reloc on A385 Turris Omnia and you are right. SPL cannot load proper U-Boot and throws error:
Trying to boot from SPI Invalid bus 0 (err=-19) SPI probe failed. SPL: failed to boot from all boot devices
Stefan and Tom, it is possible to somehow "inject" dm-pre-reloc into spi DTB SPL node during SPL compile time when CONFIG_SPL_SPI=y is enabled?
Because really CONFIG_SPL_SPI=y option does not work without dm-pre-reloc.
Automatically? Not at this time, that's what -u-boot.dtsi files are for.
This issue is arch/arm/mach-mvebu generic, not board specific. SPI NOR node is defined in SoC .dtsi file, not in board dts file. -u-boot.dtsi is board specific, right? Therefore if -u-boot.dtsi is used then this setting needs to be included in every one mvebu soc -u-boot.dtsi file? This does not look as an ideal solution.
There's a few different -u-boot.dtsi files that may be included, see the logic in scripts/Makefile.lib. But if there's already a board one, it may need to #include the SoC one.
