Is there a reason to remove this? It's checking the file type of the passed in file.

• Adding description into the file, so that everyone could now how to use it with U-boot

Done with the changes!

Updating D39164: [ARM64] Provided initrd in "linux,initrd-start" and "linux,initrd-end" props of FDT /chosen node, mount it as an in-memory startup disk (mfsroot).

• No need for __FBSDID, and cdefs.h can be removed as it's only needed for the macro
• Correcting identation, adding fdt

Hi @luporl @leandro.lupori_gmail.com @bdragon ! The method of loading initrd from /chosen FDT node you have implemented in sys/powerpc/ofw/ofw_initrd.c is universally useful across many targets. In this revision, I'm copy-pasting your code into ARM64 target. But what do you think about sharing sys/powerpc/ofw/ofw_initrd.c at a higher-level directory? Would it be possible to mask out the following PowerPC-specific lines (please see below). Kindly looking forward to hearing your thoughts!

Why is this in an arm64 specific directory? It doesn't appear to be arm64 specific.
