Subject: Philips GoGear SA9200 port. Working bootloader and normal builds,
 including sound. No touchpad now, buttons limited to using vol+/vol-/power
 for up/down/select. Rockbox USB is enabled since the OF is MTP only...read
 the warnings on the PortalPlayerUsb wiki page.

git-svn-id: svn://svn.rockbox.org/rockbox/trunk@17591 a1c6a512-1295-4272-9138-f99709370657
