Optional dual-boot support in iAudio X5 and M5 bootloader, based on FS#5289. In order to enable it, #define HAVE_DUALBOOT when building the bootloader. Do not use the automatically created x5_fw.bin or m5_fw.bin, but use mkboot to create a new firmware file from an OF x5_fw.bin resp. m5_fw.bin and bootloader.bin. The dual-boot bootloader boots the OF when pressing Play (main or remote) for more than 3 seconds. Hold it a bit longer because the OF also checks buttons. Short press boots rockbox. As a bonus, the Play button read (for hold check) is done a bit earlier for single-boot mode as well. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@30018 a1c6a512-1295-4272-9138-f99709370657 2011-06-19 17:23:18 +00:00			`CONFIGFILE := $(FIRMDIR)/export/config/$(MODELNAME).h`
