Hi all, I numbered this v5 because this is still revolving around the same initial desire to cut the build time of an ARM64 kernel when toggling CONFIG_BLK_DEV_INITRD. This 4th version is basically the 3rd possible way to just get rid of __early_init_dt_declare_initrd() for ARM64. I previously mentioned that I was working on making phys_initrd_start/phys_initrd_size generic across architectures that make use of it, which would cover ARM (32-bit), unicore32 and possibly arm64, but upon second glance, this does not necessarily help, or rather this patch series actually helps make a smoother conversion in the future.
