If you can read german try this one:http://haiku-gazette.blogspot.de/2009/05/gsoc09-interview-mit-johannes-wischert.html this one gives a great overview:https://www.haiku-os.org/tags/arm If you want to have an overview about porting os in general (with sweb as exapmle) you can have a look here:https://online.tugraz.at/tug_online/voe_main2.getvolltext?pCurrPk=80479 We have a whole bunch of brilliant developers working on this since years.. it think you could imagine on your own ... if porting would be so simple the port would have been finished since years. As it looks you have basic knowledge about development so why not join in some of the projects:eg: help with porting: https://github.com/HaikuArchives/AbiWord greetingsParadoxon :)
