[OE-core] [PATCH v1 1/1] image_types: add base64 conversion

[S. Fricke]

Hi,

>    Is it?  I'm genuinely curious when a base64 encoded image is useful. 

It is! :-)
We are using a softwarestack which use base64 (I am delighted thats no one is
using uuencode ^^) encoded images to transfer them via wire. I can not change
this stack.

If this isn't useful, maybe you can help me to get a own conversion cmd into
my own bbclasses? I have tried it in several ways, but nothing worked. The
last approach was to change the image_type.bbclass.


TIA,
Silvio
