[U-Boot] Falcon Mode implemented version

Hi all,

I have the following queries.

1) Can anyone suggest me the exact version of u-boot in which falcon mode is implemented?

I also wanted to know, if is there any readme available for that implementation.

Please also tell me, "where exactly in the u-boot code" it is implemented.

2) The u-boot version in which SPL for NOR flash is implemented.

If no such version is available, then please tell me about the patch in which this SPL for NOR flash is implemented.

Thanks in advance.

Regards, Rajdeep Vaghasia.
