Hi Alice,
Would it be possible to factor out the common parts of the U-Boot SPL/Pre-relocation device tree into an imx95-u-boot.dtsi file, like U-Boot already has for imx8mp/imx8mm? From what I understand, the binman configuration and some DT nodes (e.g. soc, aips*, scmi*, elemu*, gpio2-5) are required on all boards, as they are bus parent nodes or needed by the SoC implementation.
In the downstream kernel, there are already other boards apart from the EVK (e.g., Verdin-EVK), and we’re also working on a new SoM family (Toradex SMARC iMX95). Having the common parts factored out would make things more organized and easier to upstream.
Best regards, João Paulo
Hi João Paulo,
Will move these common parts to an imx95-u-boot.dtsi file in next version.
