why would the file not exist?

This is generic rule and this is generic Versal Gen 2 board but under the same folder specific boards can be added. We have it internally for covering tests which are not possible to emulate on QEMU. That's why rule is taken when that file exists only.

Note that files should not be overlayed in the folder, boards should instead be extended https://docs.zephyrproject.org/latest/hardware/porting/board_porting.html#board-extensions
This part needs 2 space indent inside the if()

ad Note) I can't see any upstream board which uses it. (git grep "extend:" upstream/main) but will look at.
ad 2 space) yes this should be fixed. Thanks.

No upstream board would use it in-tree because it is for out of tree usage only but it is used out of tree by several users

changed the title
Add support for the RPU, real-time processing unit on Versal Gen 2 SoC. It is based on Cortext-R52 processor. The patch contains initial wiring and configuration for generic board with OCM(1MB) and DDR(2G) memories, cpu, interrupt controller, global timer and UART. versal2.dtsi contains common peripherals integrated into Versal Gen 2 SoC, and versal2_r52.dtsi has peripherals which are private to Cortex-R52 processor.
