[U-Boot] List of architectures no longer printed

[Nathan Holder]

Hi,

"mkimage -A -h" no longer prints  architectures. Is there another way to get a list of architectures?

Reference:
http://manpages.ubuntu.com/manpages/xenial/man1/mkimage.1.html
https://linux.die.net/man/1/mkimage
"-A [architecture]
    Set architecture. Pass -h as the architecture to see the list of supported architectures."

Using Ubuntu 16LTS, here is result:

$ mkimage -A -h
Usage: mkimage -l image
          -l ==> list image header information
       mkimage [-x] -A arch -O os -T type -C comp -a addr -e ep -n name -d data_file[:data_file...] image
          -A ==> set architecture to 'arch'
          -O ==> set operating system to 'os'
          -T ==> set image type to 'type'
          -C ==> set compression type 'comp'
          -a ==> set load address to 'addr' (hex)
          -e ==> set entry point to 'ep' (hex)
          -n ==> set image name to 'name'
          -d ==> use image data from 'datafile'
          -x ==> set XIP (execute in place)
       mkimage [-D dtc_options] [-f fit-image.its|-F] fit-image
          -D => set all options for device tree compiler
          -f => input filename for FIT source
Signing / verified boot not supported (CONFIG_FIT_SIGNATURE undefined)
       mkimage -V ==> print version information and exit
Use -T to see a list of available image types
