Why are we upstreaming an emulation platform? I assume you have some sort of scripts or something to load the kernel image into the emulator, so those scripts could go and modify the dtb in place to populate the initrd and commandline.

Similar to > https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/arch/arm/boot/dts/qcom-msm8974.dtsi#n89 And the hardware is not emulated properly to report the actual frequency that the timer is running at? That's sad. At the least, this should be in the board specific dtsi file instead of the SoC specific file, because it's a board quirk.
