* read system firmware version from nand

* add pfs support, write directoryentry info for romfs files

* add file check in fsp-srv:8

* add support for open fs of internal files

* fix filename when accessing pfs

* use switch style paths for contentpath

* close nca after verifying type

* removed publishing profiles, align directory entry
