Rename argon.c to argon_wrapper.c so we can use 'argon' as the library name. Move the include file into the normal place. Add SPDX tags but otherwise keep the files as is. The code style uses spaces instead of tabs and has other differences with U-Boot Co-developed-by: Claude <noreply@anthropic.com> Signed-off-by: Simon Glass <simon.glass@canonical.com>
