PS3 platform routines
Add new files ui/common/ps3.h and ui/common/ps3.c with platform specific routines to access the PS3 flash memory and to get and set the PS3 video mode. The flash routines use the ps3-utils library. Signed-off-by: Geoff Levand <geoffrey.levand@am.sony.com> Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
